Checkpoint 8

By this checkpoint, you should have a rough version of the entire project done. Your car should be able to follow a track, which will be set up in a figure-8 shape and following NATCAR specifications (single line in the center of the track - note that this is different that the Freescale Cup track). Your control loop should be stable enough to not lose the track or be confused by the self-crossing track.

The figure-8 track specifications are follows:

  • 1 meter radius on each circular lobe

  • 60 degree linear crossing in the center, line segment beginning tangential to the circle

  • White tape on dark carpet

Checkoff Procedure

  • Your car will be dropped from a 1-foot height, simulating a crash. Nothing should break loose, and the car should continue to function.

  • After being dropped, the car should acquire the figure-8 track and run three consecutive full laps. You may use a wireless command to tell the car to start or stop running, but no other commands may be sent to the car.

  • There is no speed requirement.

  • It is highly encouraged for your car to have a e-stop which can be easily actuated on a moving car. Just in case…
