The sweeping idea is beginning to frustrate us, it seems that IR Remote Controls only send the device code once, when you orignally push the button, so as long as you push and hold the button and the remote control is in line of sight of the receiver, the robot gets signal, but as soon as the receiver loses signal from the IR Remote Control, by going out of line of sight, if you do not push the button again, the receiver does not know that you are sending the signal to it.
