PROBLEM TO BE SOLVED: To provide an infrared ray transmitter for a control unit, an inexpensive infrared ray receiver for a controlled unit, and a remote control method of a personal robot for a controlled unit which does not need such an infrared ray transmitter like a two-way remote control system. SOLUTION: It is possible to detect the circumferential condition before and after sending a remote controlsignal, judge whether the controlled unit has moved or not by detecting the change of the circumferential condition, change the transmitter direction using the transfer means provided in the personal robot if the controlled unit is not moving, and let the controlled unit operate only by one set of a remote transmitter-receiver by repeatedly operating the controlled unit without fail until the controlled unit operation is detected.
