It depends on what type of control signal is sent through the controller cable. If the signal is digital, then it is encoded by the remote control, and decoded by the robot, then the power control circuits. You have to put a modulator or transmitter of radio frequency and Infrared Remote Control and a receiver and demodulator in the robot. If the signal is analog, multi-strand, or both, then it is more complicated. Especially if some of the drive / controller electronics is in the remote, and the robot is only engines. You may be able to encode / decode an analog signal, but it becomes more difficult as basically start needing to replace its own internal circuits, instead of adding. Another option in this case would be placed in the robot controller, and make its own remote control that will handle the original controller.
