From the beginning, I wanted the robots to have the same interface to the cars as a human player. Robots can operate the throttle, brakes, steering, clutch, shift gears and that's it. The robots do have some advantages over human players. They have detailed information about the track and about the car's current state. They can process that information quickly and operate the controls precisely.

The strategy for making competitive robot opponents is to calculate a good path around the track, then to operate the controls to follow that path at the highest possible speed.
