Abstract
Abstract A system for coupling a visual sensor processor (B) and a robot controller (A), so that the processing of the whole system is sped up and the configuration of the system is low-cost. To this end, the visual sensor processor (B) and the robot controller (A) are coupled together via a bidirectional high-speed data transfer channel (10, 28, l 1 , l 2 ) for an exchange therebetween of required information. A nonvolatile memory (6) and a serial interface (12) for connection to an external input/output device, are installed in the robot controller (A), and are shared by the visual sensor processor (B) and the robot controller (A) through utilization of the channel.
