TRR wheeled category

Here is my wheeled robot for the TRR 2016 (first edition !).
The Toulouse Robot Race is a competition for makers who build robots to follow a track with turns and chicane as fast as possible.

Watch the video from Actu Toulouse

The objective in the wheeled robots category was to perform 3 laps around the track in a minimum amount of time. The competitors acitvate their robot manually but the end of the final lap must be autoomatically detected.

For this robot I used a old RC car on which I made some modifications :

  • Retrofir of the steering mecanism and battery sizing.
  • 3D prints for the steering mecanism, sensors supports and electronics supports
  • H-bridge and arduino interfaces to the motors and sensors
  • Ultrasonic sensors signal computation
  • Control loop over the track barriers distance for the direction (servo control) and the forward speed (brushed motors).
  • Supervisor on the crash bumpers for a backward motion, the finishing granty detection to stop and the emergency button.

I get the 4th place at the end of the 3 trials for the wheeled category
