I'm working on another robot. A six legged non contact obstacle avoiding telepresence robot. The camera is a wireless mini cam about the size of 5 quarters stacked on top of each other. The obsacle avoiding system is from my little brother's toy car. the robot uses 2 dc motors. I'm in the process of makining all of putting the gears in the plastic chassis. The plastic is from the stylish clear clipboards for writing notes. I will keep you up to date with my project.
