    There are other ways to make an autonomous, analog control circuit for a 3 motor walker, and it would be simple to add biases to the circuit for radio control. The most common approaches are the BEAM suspended bicore or monocore designs, which both can be adapted for phototaxis, although with a little hacking, the bias could be attached to an RC circuit. These would make controlling the robot involve less wagging of the controls and more intuitive steering, reversing, etc.
