Was wondering what you guys thought the best "chassis" for robot development was. Not looking for electronics or a "kit" but just a platform with wheels (or legs or whatever). I like the idea of doing my own electronics (processors, sensors, power systems, etc.) and could/would eventually build my own from component parts, but I like the speed of starting with known motor/wheels/platform that are well matched and robust. I have already fried a servo trying to start with that. I also figure that by the time I bought motors, plexiglass, wheels, etc.
