AIRbot

AIRbot is a robot that can be controlled by a cellphone and can send images back to the cellphone. It uses a yellow RP5 tracked chassis, a transparent clear RP5 expansion plate, and a qik 2s9v1 dual serial motor controller along with the AIRcable S.D.K. and the AIRcable OptiEyes. The source code (both AIRcable and Nokia) and circuit diagrams are freely available.
