I’m thinking two things,
1st by the time you have drive control your robot is going to be hit by another and be out of control.
2nd Optics - Optical encoders on the wheels and optical mouse to senses floor movement. The mouse may need modifying so it will work a few inches off the floor. I will be a cool thing for the programs to work on.
I think this game is going to fun to build, play, and watch
