Move countersignature formula

all right so um welcome back to uh f110 autonomous racing um as you have received several announcements uh till they seen me um show you some examples of these uh coordinate frames like the map frame or something called the base link or the laser link or the lidar frame um and so i hope by now you have some intuition for why we need a coordinate system why these frames are important what they represent but we haven't really delved into the details of what are these frames what is the methodology behind naming them what are transformations between one frame and the other so i want to cover that topic uh in the lecture today uh and this also you know will serve as a transition to working and better understanding the simulator because the simulator you will see uh will utilize all of these coordinate frames and transformations that we will cover today so in in addition to that i want to talk a little bit about the tf and the tf2 ros packages which is uh what the implementation of this ros transformation um is is accomplished through these packages and so as as always with everything else i will show you the intuition first then a little bit of math to convince you how this works and what happens underneath the hood and finally we will wrap the lecture today with the overview of what some of the api calls and the package tools are available for us to interact with transformations and again time permitting i will maybe even show a demo of some transformations with turtles okay so so let's jump into the topic of the lecture which is coordinate frames and transformations so to build some intuition about why this is necessary um i want to show you this this image which compares and contrasts what the f-110 car the real hardware has in terms of the sensor capability and the compute capability as compared to you know a typical prototype of a full-scale self-driving car and i should also mention here again that the simulated f-110 car has the same virtual capability as the real car the only difference is that you know on the real car we spent a lot of time in looking at the the vsc which sends the pwm signals to the actual drive motor that part has becomes more simplified in the simulation because we don't really need a vese in the simulation we can directly control the speed and the steering of the of the car itself but that's not the point here the point here is that on all of these 110 scale or full scale autonomous vehicle setups you have a different set of sensors and each sensor is going to report data in its own local frame specific to that sensor right so the lidar will tell you distances from the lidar itself the camera is going to detect obstacles or...
