By popular request, i.e., by U of U mechatronics students, I've posted up some same sumo robot code that was written a few years back for my sumo robot Wedgie (shown below).

The following programs are intended as examples for writing your own code in Interactive C. Most students are struggling with learing Interactive C and the following examples my help sooth the pain. There is no guarantee that the following programs will work. I'm not responsible for any damages, intellectual or physical, that may result from the use of the following example programs. Use at your own risk!!
