How to drive a torcs car with a robot

After initializing all data, TORCS calls the drive function of the robot for each driving timestep. To drive a TORCS car, the robot has to set the following values:

  • Acceleration
  • Brake pressure
  • Clutch
  • Gear
  • Steering angle

These values are part of the race command structure holding the data to be send to TORCS in the Drive-API-Call.

Acceleration, Brake pressure and Clutch are normalized to be values from 0 to 1. The corresponding acceleration is calculated from the engines data, read from a cartype specific setup file. The max brake pressure is initially set in this cartype specific setup file too, but may be redefined in a driver specific setup file merged with the initial settings of the cartype. The steering angle is scaled to be in -1 +1 range. The scaling is done with a cartype specific constant, the steerlock value. The Gear numbers include the reverse gear (0), the neutral gear (1) and than the other gears (2 = first, ...). The total number of gears is also cartype specific.
