This is my first robot attempt. Pretty simple. Started with a toy mouse kit.(Two motors, wheels, chassis, and gears. Runs on a Stamp I using my own motor drivers. Time to complete about 2 days. Cost: More than it should have, about $70. Problems: The motor drivers running too hot or not at all and squeezing all that crap on this tiny chassis. Runs a basic Left/right/straight program, just to prove out the motion control. Will add touch sensors in the future as well as reverse. No URl Yet. Email: b_okeeffe@hotmail.com
