How do i industry sign banking alabama presentation online

introduction slides on is 11. it is 11 o'clock so welcome to other ash product spaces welcome to alabama astrobotic space days virtual booth please bear with us uh today as we've never done this before so this is a new experience for all of us so uh we have a qr code up there uh just asking for some information if you'd like to get in uh contact with us [Music] you can put that in there and we will send you an email later on we also would love for you to fill out this poll so we can get a sense of how many people were reaching today that's an important part for our outreach paper we like to keep track of how many people we're reaching out to so we'll leave this on screen for a little bit and we'll come back to it later as well yeah uh i think we can just leave it on screen and start to talk about the team a little bit we are alabama astrobotics we're a student design team here on the university of alabama's campus you can see we're sitting right now in our lab and we build robots uh every year we compete in nasa's robotic mining competition which is a competition that's designed uh as a an analog for lunar mining so under the surface of the moon there is icy regolith which is kind of an icy rocky substance and obviously we need water when we're on the moon because we have humans to sustain we have rocket fuel to make we have oxygen to make water gets you all of those things so we want to excavate as much of it as possible from under the ground and that's what our competition is all about so we build an ice mining robot every year yeah do you want to show them our nice boxes of our simulants yes i need to get closer to the camera yep so in the let's see a little closer so in the nasa competition we have to operate in a pit much like the one that austin you probably can't really see very well behind us but it's there it's a pit full of in nasa's case 12 inches of this stuff named bp1 it's a crushed up volcanic rock from somewhere in the western united states but basically nasa determined that's the closest thing that they could find to the uh surface layer on the moon and also mars it's kind of toxic to be honest you have to be careful around it it's basically crushed volcanic rock yeah which is why our pit is full of crushed up limestone instead fair bit less toxic but it acts more or less the same but in either case underneath that is a several inches deep layer of gravel which is the stimuli for the eyes that nasa expects to find on mars or the moon so our robot has to be able to dig through the layer of bp1 or limestone several 12 or 12 or more inches down to get to the gravel underneath pull it up and deliver it to a collection container so basically the reason we use limestone here is because in alabama it's much easier to get the 22 tons of limestone that's currently sitting in the pit behind us and also nasa it has the only access to bp1 because it's extremely expensive because it's volcanic rock which is quite rare yes nasa has access to the only quarry of vp1 so luckily uh crushed limestone is very easy to find in alabama so that is our substitute it acts very much the same thing so we have to dig through an entire foot of compacted crushed limestone to get to the gravel beneath which as you can imagine is quite a task so let's talk a little bit about our team the sub systems that we have and what each of them do all right first up we have the mechanical team they designed the robot to meet all of physical requirements such as the size constraints being able to reach down far enough to pick up the gravel and being able to offload what we do pick up into the collectors at the end this is quite a complicated task specifically this year as the size constraints for the robot are very small yet we still have to dig down 16 inches yes 16 inches um the next subsystem is electrical they are responsible for supplying power to the robot and all of its logical systems and moving all the components they act as an interface between mechanical and our third subsystem which is software who is responsible for writing all of the software for the robot to allow it to operate we also um in addition to just driving the robot around have made it fully autonomous which only uh which we are one of only two teams in the last competition to have accomplished so yeah autonomy is really important in this application uh it's very difficult to physically control a robot that's operating on the moon for several reasons one if you do it from earth you have a bit of an information delay a time delay for the communication and two if you do it from the moon astronaut 5 is really expensive so it's best if these can remain fully autonomous the basic math there with the even when you're on the moon is as the as the astronaut is using the robot they're using up oxygen and so every piece of ice the robot digs while the astronaut is operating it you're losing a bit of that because you've got to make more oxygen of what you just lost so making it fully autonomous saves everyone a lot of hassle and a lot of time in the long run and also at the current moment just since launching astronauts into space is very very expensive so until we get a little bit more of a reliable human transport system we're going to need autonomous robots what's the price for um enough water for one human to survive on the moon for one day i don't know but it does cost roughly one million dollars to send one kilogram of mass into space gosh it's expensive expensive which is one of the reasons why our robot is actually limited by mass as well as size the approximate launch volume of the average uh space payload according to nasa is approximately the size of our robot so we are only allowed about half a meter by half a meter by a meter of space and only 60 kilograms of mass that's small yeah it is small and when you really think about that like that's about 19 inches tall the robot is allowed to be and to successfully mine a decent amount of gravel it has to be able to dig about 16 inches down so you don't have to be able to dig most of your life down beneath your height so it's quite an interesting challenge yes we actually have a question from the chat and we asked isn't it kind of boring doing the same project every year no it is not uh so nasa actually has changed the rules uh over the 11 years the competition has been running when it originally started out the goal of the challenge was to only mine the surface layer of bp1 later on they changed uh the challenge to also include the gravel underneath and even more recently um they removed any points you get from mining the surface layer of vp1 but now you only get points for mining the lower layer of gravel furthermore uh nasa has just recently built a new indoor arena where the country needs to be held outdoors the serene is smaller than the old one used to be and to accommodate this along with what nasa sees as their goal for actual uh mass and size constraints they have reduced those significantly from the last time the competition uh was run so uh ben what is the main reason that we think nasa got rid of the ability to score points off of mining lpp1 so [Music] uh our team has historically been extraordinarily successful in this competition uh and so as um we progress and more successfully uh mine uh nasa is increasing the level of difficulty for this challenge uh as per with their goal to um to keep the competition relevant and interesting what ben is trying to humbly say is that we got too good and so they had to make it harder was that 300 kilograms of 51. something like that i thought it was 130 kilograms in the final year before they changed the rules it was a very large amount of bp1 and nasa was like well you guys have kind of broken it we know how to do this now the short answer we solved the problem so the problem had to evolve they had to make a new problem yes so we've won the competition six times total uh and that is the last five times in a row and we would have i can't say we would have won last year but i think we would have won last year if the competition hadn't been cancelled because of obvious reasons yes so unfortunately the last two competitions have actually been cancelled um the year before last year which is 2019. um is that right yeah it was the 2019 competition yes yes the 2019 competition was unfortunately canceled uh due to logistical reasons and this year the 2020 competition was cancelled due to pandemic reasons so unfortunately we haven't been able to compete in a in a while but we are still working hard we're building robots we're doing everything we can do yeah and the first year when the competition got cancelled we partnered up with caterpillar and hosted a version of it here we also we didn't host it caterpillar hosted it and the university offered our facilities yes because they needed because we still wanted to compete and we competed in that competition and we won that competition as well yes so it's like we've won seven times did you want to show the conversation video i will show after we show the quick picture one thing i'd like to mention first is that our faculty advisor dr ritz has corrected us and that phony year before nasa said that the fluffy regulus was worth nothing the first competition run was 163 kilograms of it and the second run was 173 which is a record in the competition by quite a long shot so it was a total of over 300 yes and to give you some perspective for that each one of those runs was only 10 minutes long so for a total of 20 minutes we got three over 300 kilograms of bp1 which is a lot compared to most teams which don't get much at all uh so this is from [Music] so uh these are some pictures from that robot we mentioned two years ago that actually have uh compete here at our own facilities in the caterpillar competition this is the robot that we lovingly named bessie and i guess i could start going over like the general web operations we have a couple questions from the chats first um do we have a competition next year yes we hope so we hope so very much nasa has actually restructured the competition this year uh it's built in several different phases so if the actual physical competition is not able to be held they will judge on the previous phases so they've built in a contingency plan and we're hoping that we won't need it we really really hoping three of us who are sitting here have been on the team now this is our third year and we have never seen a competition actually happen in uh florida we're starting to feel like bad luck sharks but i'm the lucky one i got to go to florida once yes um we are indeed tied with the football team for national championships yes yes so yes that is a good a good point we do like to brag about that so this is the pictures of that robot and next slide is the video all right you want to go over the operations as i so rudely interrupted you before i can or uh did you say you're gonna do it i can do this uh so basically you're about to see our robot run uh okay that's fair it's a long video so this is a 10 minute content run so with there we go so the robot begins by spinning around and using the red and gray beacon you see on the side are red and grey objects inside your mouse can they see it with your mouse i do not know let me know if you guys can see where i'm gesturing but perfect this beacon right here is used to localize using the lidar on the back of the robot it basically tells it this is where this is so i know where everything else in the arena should be it then makes its way across the obstacle zone which is filled with these rocks as you can see here and some craters and we use front we use another lighter on the front of that robot to detect those obstacles and attempts to use path planning to avoid them now the robot has reached the excavation zone and it begins lifting the digger head into the optimum angle for digging now begin spinning uh the teeth forward as a trencher and it will begin deploying using two lead screws into the ground to dig up the uh top layer and as you can see our off-loading belt on the back is uh currently spinning so as to not uh keep the fluffy stuff on top of the limestone because we don't care about that because it doesn't matter for points so we just dump that behind us and then as we start getting to grab a layer the belt will slow down and eventually stop and then it will begin shaking back and forth to in a sieve in a way to sieve off any other limestone we picked up yes our offloading belt is perforated to allow for the soil to pass through when you shake it i'll say a couple things about our trencher um our trencher is the best way to be found to excavate gravel from under the soil uh reduces the digging forces required if you think about it overhand a much more natural digging mechanism if you think about how a dog digs digs overhand in the dirt he doesn't try to scoop up the the dirt with his paws so it's a much more natural mechanism and it allows us to minimize the digging forces like a few years before this we use pregnancy offset mechanism calling it a bucket ladder instead of a trencher doing the uh overhand digging instead and if you go back and watch those videos you can see that that mechanism would often stall and have to recover from that losing its time that's material we can't dig with time we don't have so we discovered that quickly changing simply changing the direction increases the performance significantly yes the bucket ladder was previously the best mechanism for digging up the overburden the soil that's on top because it's a lot lighter a lot fluffier a lot easier to pick up we have a question what different majors are represented on the team a lot of them uh we'll just quickly go over ours i'm a computer science major i'm computer science in german major computer engineering aerospace engineering so we have all of these as well as mechanical engineering chemical engineering civil engineering english english um we have a couple business majors on the team what else math majors computer engineering as well as computer science electrical engineering basically every category of engineering that the university offers we probably have one of them on our team or we have in the past except for maybe middle earth i don't think we have a little bit i don't think we currently have i think we have in the past though yes well i learned new things every day so it's definitely not a requirement to be to be a particular major to be on the team like basically if you're interested you can be on the team so we have so many different majors and not all of them are engineering uh like we said we have a couple business majors who help us out with our uh more logistical side we have an english major who helps us with our documentation and our papers so we really take anybody who's interested in robotics or just the way that the team works so uh the this is actually only the first dig dumb cycle for the competition right so i don't want to show this whole 10 minute video but as you can see there's a lot of rocks over here that we just don't and when the robot makes its way back it uses a similar way of using path planning i think that you did it just normally default to taking the weight back or did it try to back up and pass one all the way back to the numbers two years ago so that one right there i believe would be about 16 kilograms of gravel to sitting right there because the entire run was about 33 kilograms yes that's another record yes not to brag but we're bragging right that was that was another record-setting amount of gravel at about 30 kilograms of gravel yeah so how many students are on our team uh on our roster we have about 68 people probably around 50 of those are currently active yes so we have quite a big team we have a lot of work to do so we try to spread it around as much as we can we have a smaller leadership team of about eight people who uh organize everything we're the leaders um but we try to spread the work around as much as we can since we have such a big team yeah so i think [Music] okay so here you'll see um a bunch of different ways you can contact us and go to our website you can find us on facebook or twitter or instagram we have a youtube page which has all of our competitio runs on it um please if you want to contact us do there's a contacting form on the website i believe as well as a couple of emails that yeah dr x's email is on there i believe our social medias leave uh social media leads emails on there also all of our social is listed on our website so if you go to our website you'll find everything there yes yeah as well as links to each of the social so you don't have that correct yeah let's go back to the qr code just in case anybody um oh doctor brings out a good point the trencher consumes significantly less power than the bucket ladder does which is also uh a stone motor is pulling a whole lot more power than one that isn't that's basically you sum it up right there if you don't sell the motor your motor is running a lot cooler no less power points so in the competition uh power is one of the scoring mechanisms so the less power you can draw uh the higher points you score uh which aligns with nasa's goals uh as um if a robot is on the moon or mars uh they need to supply it with enough power to dig and the less power they have to generate to do that obviously uh the more efficient it will be it has to spend less time charging and spend more time digging and in all reality it will probably be solar power uh when these robots are actually on the moon we use lithium batteries but solar power tends to be a little bit slower with the current technology so less power the better we have another question what's the approximate breakdown of men versus women on the team i do not know the actual stats for this which is unfortunate i don't i could go i could go do this math real quick it's probably about a quarter do you think a quarter woman yeah right a quarter to a third maybe yeah there's representation of the upon all all the substances yes yeah but i don't know the exact word yeah i'd say important our admin team is 25 female if so that is a good representation yeah that's it for you last year we actually had 50 uh on the admin team 50 women so we're uh doing everything that we can to get more more women on the team more women interested in stem is always better [Music] this is also a good a good representation mattress yeah all right so just to repeat this qr code will take you to a poll we would love for you to fill this out because it gives us some information on how many people are reaching yeah uh so you mentioned the power for the points you want to talk a little bit more about how the competition is sport yeah so uh where the competition works is that if you meet all of the mechanical size and mass requirements of inspection before before you run you are granted 1 000 points uh then your mass and the power consumption along with how much data you use communicating with your robot throughout the run are deducted from those 1000 points the way you gain points are for every um kilogram beyond the first kilogram of gravel that you collect the first kilogram of gravel that you collect is simply to qualify you for the competition so if you don't collect any uh gravel during one of your competition runs it just doesn't count right um so you get points for every kilogram of gravel beyond the uh the first kilogram then you also gain points for being autonomous uh this is structured in a um in a progressive way where if you um only do uh if your robot is only running autonomously while it's in its digging operation and then is manually controlled for its driving uh you will get 50 points around there then if you can traverse from uh the starting zone to the mining zone successfully at least once you get around 150 points uh then if you can uh complete an entire run there and back so uh traversing the optical zone digging autonomously and offloading on honestly you get around 300 points and the uh the top prize for autonomy is if you can complete the entire um cycle which is two full autonomous runs uh fully autonomously without interruption and that is around 500 additional points so that's obviously always our goal our goal is to sit down with the computer press enter to start the robot and not touch the computer again and we usually uh we usually complete that there's also points like i think you starting out points and they get deducted for the amount of bandwidth you use yes that's what it works yeah so obviously if you're able to remotely control your robot entirely you're going to be constantly in communication with it that could potentially use up a lot of data especially on the kind of low speed links that we may have to robots on mars for example so if your robot is autonomous you also have kind of a natural benefit in that that also ties into there's cameras that encompassing nasa lets you use if you don't use those there's also benefits for that yep furthermore uh we have found through experience that running the robot autonomously is simply more efficient that the robot can know how to run itself better than someone sitting in a different room using a mouse and keyboard or a gaming controller to drive the robot it simply works better especially since in the competition nasa places a delay in your communications because obviously when you're talking from earth to mars there's this thing called the speed of light you have to deal with so your communications may take depending on where everything is in their orbits anywhere from like 15 minutes to 40 minutes to get from one point to another nasa doesn't make the delay that severe like i believe in competition it's two or three seconds but that's still plenty enough to throw off someone trying to remote control our robots do we talk about max all right uh we have stats from dr rick's officially females make up 21 of the team so about about a part about a fish yeah all right um we have some questions about our outreach what what kind of outreach do we do so part of the competition is an outreach report so we want to reach out to the community around us to the k-12 community especially and our goal is to inspire a love of stem and robotics so we do a lot of outreach with elementary schoolers with k-12 schools with high school robotics teams we just want to reach out to our community help in any way we can in the past we've done a lot of projects um like community service projects we've built cars for children with disabilities so that you can drive around we have built um a sensory interaction machine for uh children with sensory deficiencies we've done a lot of really cool outreach stuff um our goal is always just to inspire a passion for stem this year obviously with uh restrictions we have we cannot do as much in-person outreach if any so most of our outreach this year has been through virtual and nasa made it a requirement that at least 50 of your outreach must be virtual uh so we are doing a lot of that this year so we are also having to adjust the changes with the world we live in today yeah so as part of the competition in addition to the actual physical presence of your robot digging gravel you get points for well outreach as we're talking about now nasa is very interested in um developing interests in stem technologies and um you know their future missions to the moon and mars also uh we have to document our entire engineering process and we get assessed on that uh this year more than usual as the beginning phases of the competition are solely based off of our documentation of where we are in our engineering process and there's uh this year there's a gateway where you must pass a review by nasa in those early phases to be allowed to go on and compete physically yes so uh systems engineering is a big part of our competition we write a systems engineering paper which is about 25 pages long that documents the entire process that's due about april so we've already started working on that uh we have another question about what kind of non-technical skills we've learned from being on the team it's public speaking yes that's that's a big thing yeah before covid we used to be in the lab all the time and we would have tours that would come in because we are on the college of engineering is very proud of us so they put us on the pretty much the end of their tour so we used to have maybe four or five tours every day if it was a friday it would be five or six and someone would always get up and give what we call the spiel which is basically what we said at the beginning of this but in person showing everything uh so yeah so that definitely became a thing of having to speak to strangers on a regular basis which is a good skill yes and there's also at least for those of us on the admin team kind of leadership skills because a lot of us may know how to actually get this sort of work done to make the robot but we may not know how to guide others as a community of effort to get the project done so that's something a lot of us have to learn kind of on the job so to speak your classes uh you know you're focusing on something uh very narrow very specific towards your major uh and you're more than not working alone or maybe with one partner on a lab uh and in this competition obviously as we just went through there are many different majors there's many different facets the project and so you gain a lot of experience knowing how to work in a team and uh how your contribution fits in with a larger project and that's extremely valuable yeah i think that one of the most important things you can learn on this team or any team like it really is interdisciplinary communication uh in work always you're gonna be dealing with other people you're gonna be communicating with other teams and that's not something that you learn in class really so uh i as part of the mechanical team have to communicate with matt who's part of the electrical team and we have to figure out how we can uh get both of our requirements fulfilled while fulfilling the larger system requirements and they throw it at software they're like make this move yes yeah electrical accounts will be the immediately between the two of them software mechanical so gets to be able to fit both of their needs make sure they communicate with each other to get between the virtual world of the physical world yes so we learn lots of non-technical skills uh communication and leadership are really important um in my opinion the only way that you can really learn to be a leader is by doing it so this is a great opportunity uh for that let me get another question what kind of role does a freshman play on the team i'm a freshman and to be honest i don't know much but i like to learn that's it that's what you need it's what we're all here for you need a passion for learning i i joined this team my freshman year within the first couple weeks and i knew barely anything about robotics and i also knew barely anything about programming to begin with because i was a freshman computer science student but i started and i began learning and i spent maybe too much time in the lab which was our old lab which was a lot smaller and not as nice as this new one so yeah but yeah no it's definitely this team is what you put into it you'll get out what you put in so the more time you give the more interest you show the more likely you are to get those skills we talked about out of it and get the meaningful experiences if you're someone who already has some of these experiences like if you did first robotics for example or something like that that's incredible your experience will be very welcome but if you also don't know that sort of stuff this is still school we're all here to learn why we're here so if you need to learn this we'll happily show you along the way yeah we like to say that all you need you don't need any prior experience you don't need any prior knowledge all you need is a passion for robotics and the time to learn it so madness and many times the things you learn here will help you later on in your classes because a lot of times things that we do you're not going to do for some weeks or semesters and that can be super useful there are programming things i learned here that made it when i got to them in class made my life a whole lot easier and i assumed the same was for mechanical and electrical yes for sure absolutely let's talk a little bit about our new lab so this lab was constructed not constructed but outfitted for us in january of 2019 by the college very kind of them to donate us this new space so our old lab was also a college space it was excellent it had a big pit full of sand that we could test our robot in and this lab is actually even better so we have this pit back here that's full of fresh limestone it's encased with glass and it is a perfect analog for the testing facilities that we're actually going to face when we go to competition this is one of the only logs like this in the country which is incredible for us to have as a resource that's part of the reason we were able to host the competition two years ago when nasa was not able to if we had if we had only had the old lab we would not have been able to do that that kid was extremely small compared to this one and a lot more cramped tight space whereas this lab is much i wouldn't say larger it's about the same space really but it's more open and we our old lab we shared with two other design teams uh and this one we have all to ourselves it's very nice yeah so we have a bank of computers back there that you can't see right now for our software team to kind of have their own little space we have all of these big mechanical tables that you probably can't see because they're out of frame but um we built these tables ourselves previously we only had room for one and now we have four which is incredible for the mechanical team uh trying to build a robot on one table is no fun we went up on all of them we went from one to four and somehow we always managed to just have to fit all our stuff on one table and immediately all four tables seem to be full of stuff yes it's weird how that works it is weird how that works you use the space that you're given and we are so lucky to have this space we also have a whole slew of tools and cabinets uh that are perfectly fitted for our team we have a whole electrical station over there that you can't see right now i'm sorry that you can't see more of this i think online there's a virtual tour of our lab somewhere on the engineering website probably probably i'm not sure where that is there are also pictures out there um i can talk to cat about posting some pictures of the lab there's our song on our instagram for example and probably other social media too yes so definitely does it there but yeah so our love it's very nice it's also card access so we know everything will be safe and we feel safe leaving some of our very expensive equipment in here yeah and yeah all right we have some questions from the chat is there a performance metric or score consideration for robust or continued operation through either an onboard failure or perhaps extreme terrain or strata insurgency tests ai navigation control and mechanical robustness so i think that there are several aspects of the competition that deal with this we have we get points for being dust tolerant um so as a result of the soil uh that we use even just the limestone it create it kind of aerosolizes and it creates this cloud of dust in the air so that dust settles on every surface not just in the pit too everything in the little slab is covered in dust we have we have a vent hood you can probably see a little bit of in the pit to get rid of some of that aerosized dust so it doesn't get in we also all wear respirators while in the pit to avoid breathing that in because that is not good for you but that kind of deals with the mechanical robustness of the system um for the software side i'm not sure that there is a mechanic in the scoring for that but we do several things for that if you're talking about that so as part of the competition obviously we have to navigate some obstacles and that really plays into the autonomy side of things um the autonomy system is responsible for navigating around those obstacles and obviously you can get a lot of points uh generally we get uh probably 10 or more times as many points from our autonomy system than we do from digging gravel and so as a requirement or that we're not allowed to touch the uh the computer and so if the robot does run into a situation where it um has to navigate some complex terrain um obviously the software has to handle that properly and um time to and if it's first plan doesn't quite work out it needs to replan and it needs to be able to gracefully degrade as well if we are unable to accomplish our top goal of full autonomy we need to be able to recover from that uh manually controls to get out of whatever situation we were in and then resume autonomy to get as many of the points for the lower categories that we can and uh that's especially true this year and last year because nasa increased the size of the obstacles to the point where the craters can be about as large as the robot itself so we very much have to avoid those craters otherwise we'll sync ourselves and be pretty much done for so it's very software autonomy is very much about the obstacle detection in the last couple years because of those new obstacles yes so to answer the question about kind of the testing of robustness there is not a um a scoring metric in that for the competition but we do a lot of that ourselves we do a lot of robustness testing also the competition is comprised of two runs where your scores are added together and that helps to [Music] ensure that the robot could not just perform a one-off uh that it needs to be able to repeat its um its success the obstacles get changed between each run between every pretty much every team that runs the obstacles get moved around so a team can't watch a previous run and then go okay tell the robots to go on this exact path because if they did that they'd probably run into a new obstacle so we have some more questions if any of you have had some internships how is being on this team been helpful with those so personally speaking um i interned at ula over the summer and i'm planning on going back next summer uh in my interview i talked almost solely about experiences that i have on this team so the iteration that we do the design the problem solving the teamwork the leadership all of that is helpful in building skills that you need for an internship and building experiences that you can talk about in your uh in your interviews does anybody else have uh last summer i interned at caterpillar and i would say uh the number one reason i got that internship was because this team uh that i was calling up my contacts of eric reiner's he's in the chat uh i don't think he said well anyway he's who i met at the competition and uh he kind of recruited me in the caterpillar and yeah so this team was a tremendous uh opportunity generator yeah so since our team has a uh reputation of success and of just really good people coming from it the opportunity of being on the team in and of itself can get you connections and experiences and opportunities that you wouldn't have there have been companies that come straight the engineering department brings to our lab because like these people know what they're doing you should ask them about internships i was supposed to have an internship last summer but i had to diverge next year but in that interview most of what i talked about was astrobotics is when someone asked you uh what was the situation where something went wrong you had to find another solution for it my mind normally goes here because something happened on this team where i had to find another way to do it so yeah so it got me my internship sadly did not get to do it that kind of leads into our next question uh what was one of your most satisfying moments when you were building or testing the robots yeah i'd stay after the second one yeah if i wasn't affected yes if um okay so there's actually evidence of this like uh dr phil metzger like posted a like two minute video on his uh twitter account like if you scroll farms back you probably can still find it the last two minutes of our second competition run in 2019 i believe that you already saw one part of that run like the first half of that run but the last two minutes of it he was walking around in here watching us be extremely intense worrying if our robot was going to work because our previous consciousness run had not been so successful we had some maintenance issues that had to be dealt with and we were behind the competition and we needed a really good score to win and in this run we happened to get the 33 kilograms of gravel which is the world record world record and then you hear the countdown five four three two one stop and we all start celebrating yeah uh this is a special this was especially gratifying because the previous 48 hours we had worked basically around the clock maintaining the robot replacing parts fixing problems and the beginning of that room was so tense we were all just waiting with faded breath to see if all of our work had paid off and it had which was a magical experience that was incredible imagine if you were watching this from 200 miles away because you had to go home because you got the flu and i was watching it just losing my mind because i was so far away and i couldn't see anything don't get the flu kids yeah um all right we have another question are international students allowed to participate uh it's an access competition so i'm unsure i don't know the answer to that question i would say you're allowed to you're allowed to be on our team i'm not sure if you can be on our nasa roster because nasa does have very specific rules i'm betting you could be on ross i'm pretty sure if you're a part of a u.s university you are allowed to be in the competition uh the line is drawn where universities outside of the us cannot yeah i i believe in one year nasa did expand the competition to have international teams like they don't do that anymore though but i'm but i'm betting if you are an international student who's at ua yes you could do everything that anyone else can do with you uh dr x answered the request this question in the chat as well uh a lot of the same things we said about the two competition runs you can't just get lucky and have a hail mary run um and he explained that we put our pump or our robot through about six weeks of very rigorous testing before the competition so we we use it we break it we fix it we break it again we fix it again and we try to solve every edge case that could ever happen to it yeah so that is how we test we need as we found out in our first competition run of the last competition uh all it takes is one part on your robot that gets overlooked that has been running for a number of weeks to come a little bit out of alignment and it can uh really wreak havoc and so yeah it's very important which is why we now have log sheets for what parts have been run for what amount of time yes to stop that issue it's very important to keep track of how often you need to maintain your robot um how far apart are the competition runs days yeah uh the the competition itself is five days long the first couple of days are practice runs so you can practice in the competition pit but the actual competition runs i believe occur across three days so at most they could be two days apart yeah generally it'd probably be about one day yeah it depends on how the schedule goes because especially when you're down at kennedy space center they have let's say constant increment weather so that can be a concern sometimes there are delays indoors now i'm speaking from the year when they were still outside yeah they're indoors now so that's probably a problem now but you have to deal with 50 different teams he's doing two runs so you have about 100 runs you've got a schedule and you don't want to put a team to have to do a run back to back because that would be this unfair so there's a lot of ways they got to go about that that being said though you do have to have everything that you need down there so um generally it's going to be cost pivoted for schools to bring down two robots or um just logistically impossible to bring you know enough spare parts for every perhaps every component that might break and you do have limited space as well to work on your robot so uh making sure that your robot will withstand all the practice rounds and the two competition runs is very important yes dr works has answered in the chat yes international students on u.s university teams are allowed there we go we'd love to have you come on over another question how many universities compete don't know so the answer to this question is typically 50 5-0 but this year uh as many teams as possible were allowed to register for the first phase of the competition and then the review gate at the end of this semester so in december we will find out if we've passed um the review mate serves as the down select to that 50 that usually competes in the competition so there's more of it's more of a typical um engineering proposal type schedule now so the 2019 caterpillar robotic mining challenge yes that's your challenge challenge not competition uh i believe 28 teams yeah that was the competition that was held here in our lab and that was 26 or 2018 showed up fun fact 2018's registered in 2016 so fun fact the last time i was in the basement of one of our engineering buildings for those of you that know that building the basement was where we housed all of the robots before competition the last couple times i was there the tape that we used to separate the arenas is still there yes it has been two almost a year and a half now since then so we had to say a little bit more about this competition before we go we had our work areas sectioned off in the basement of that building we had a competition going in here it was organized madness we also at that point still had access to our old lab so we used the sand pit as a testing pit and it was so we were across pretty much the engineering side of campus and we were just all across it uh i was running a lot of the computer systems that were keeping video in different places we realized if you run a bunch of wi-fi routers in the concrete fox you're going to have issues which is basically what the basement of nerc is so it was a lot of logistical fun for that weekend for that week so we want to reiterate that we're definitely open to answering questions if you want to type them in the chat um or even if you want to just shout them out we're open to answering questions and i think we have about 10 minutes left before we end and people might start dropping off to go to the next session but i'm gonna go with this uh love to have you thanks for showing up thanks for joining us for a good morning of robotics yes if you have any other questions after this feel free to contact us contact us through the link on our website there's a whole page for that and feel free to follow us on all these socials i know we do we post some pretty cool stuff our social media lead is constantly posting on twitter and instagram so check us out we got some we got some cool stuff she likes to post memes you got more questions excellent how do we join so you join by expressing interest so there's a contacting form on the website that says hey i'm interested in the team and we will get in contact with you if you fill that out yes uh we will be having another so we have two rounds where we admit people to the team one at the beginning of the fall semester and one beginning of the spring semester so don't be concerned if we don't get back to you for uh you know a little bit here at the end of the fall semester uh that's just something we do to help manage logistics so that we're not constantly monitoring a roster and trying to get uh people in the know uh when we're in the middle of trying to build something so hang on tight and at the beginning of the next semester we'd love to have you we normally have some kind of kickoff thing at the beginning of fall i don't know if i'm going to be doing one next semester we may do one if we see that much kind of interest um so remains to be seen but yes do they contact us we'll receive emails and we will look at all of that and we will welcome you next semester yeah we also have a question about where the lab is uh we're located just off the quad we're in one of the bureau of mines buildings we're kind of hard to find unfortunately uh we're still working on our signage but unfortunately the lab is not open right now for visitors but please contact us on our website if you have interest please do i i would we would love to just give you a tour but unfortunately that is logistically impossible right now it's very sad i never thought i'd miss people walking in and giving them tours but i kind of do it's nice to show off the lab it's nice to show off the lab it's nice to introduce new people to our lab so now we just watch people walk by and look at our lab and watch someone explain to what we are but we can't say yes it's very unfortunate thank you to everyone us thanks for everyone who's saying thanks in the in the chat and we would love to uh talk with you guys later too [Music] yes thank you so much to liz moore and college of engineering for us allowing us to participate in space days we love this week uh it's so great to see all of the space industry come to campus and kind of see it come alive this is what i live for so we love space we love space here yes thank you for everyone you showed up we're all tied
