This is my first robot: robby and RP6 robot. It is based on a ATMega32 controller which is programmed in C. It's an highly extensible platform build from high quality parts. The robot comes with detailed instructions and manual. For more info, have a look at http://megabotblog.blogspot.com/search?q=rp6
