CURRENT LAB PROBLEMS
  • Car 2 is noticeably slower than the other cars. I think the same problem affects also the performance over time. The dynamics seen in car1 and 3 caused by the capacitor does not seem to reach a steady state with car 2.
  • Both cars 1 and 3 (I couldn't check car 2) have biased steer. When the steer input signal is 0 they turn left (in car1 this problem is very evident).
  • Cameras should be screwd to the metal support. Now everytime they move, the calibration must be done again. An extrinsic calibration (at least) should probably be performed again after this job.
  • Sometimes the two chargers close to the whiteboard display the green light when cars are connected (i.e. they're done charging) but when I move the wires the light turns red.

  • The car number is on the heatsink on the motherboard hidden under the adhesive paper ring.
  • Car circuit model.
  • CPS code currently doesn't compute the vehicle heading by checking the line on the cars' symbols. It just checks the previous and the current position to do it.
  • How to use Moto.exe.
  • One must pay attention whether there is some overlapping area between two adjacent cameras.
  • Substitute power supply unit (PSU) when there no signal from motherboard (connect to the screen to test it).
  • ca2 "Host-Stem Link: DOWN" message: try to reset baudrate console and set it back. Otherwise hardware reset. Suggestions about how to perform the hardware reset procedure (attach resistor to serial cables). Differentiate between reset brainstem (tea and reflex files are not touched) and configuring a brand new card.
  • Car 3 was slower than car1. The fault was probably a wheel that did not spin properly. Greasing a bearing seemed to fix the problem.
