Abstract
In an optical tracking robot system, a target has a light emitting section with a high light emitting directivity, for emitting a light beam modulated into pulses. A tracking robot has a tracking sensor section for monitoring a light beam by a pair of light receiving elements, for processing signals from the received light beam, and for generating and supplying drive control signals to a travel control section. In response to drive control signals the travel control section generates and supplies drive signals to a driver section. The driver section drives the tracking robot so that the robot advances while turning to the right when the output level of the right side light receiving element is higher than that of the left side light receiving element, and to the left when the latter is higher than the former. The robot also has an approach sensor section which detects the light beam by means of a light receiving element, and generates and supplies stop control signals to the travel control section. The travel control section supplies stop signals to the driver section, thereby stopping the robot.
