how to build a wireless remote control for a toy robot that can walk?
if we have a small toy that can walk if you control through a remote control cable. then how to build a wireless remote control for the toy
It depends on what kind of control the 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 feed the control circuits. You have to put a modulator and RF or infrared transmitter and remote control receiver and demodulator on the robot. If the signal is analog, multi-threaded, or both, then it is more complicated. Especially if some drive / controller electronics in the remote and the robot is just the engines. You may be able to encode / decode an analog signal, but becomes more difficult as the need to basically start replace the internal circuitry of its own, rather than add. Another option in this case would be to connect the controller to the robot, and make your own remote control that will handle the original controller.
