AN INDUSTRIAL ROBOT SYSTEM COMPRISING A PLURALITY OF ROBOTS AND A PLURALITY OF SAFETY SENSORS

摘要

The present invention relates to an industrial robot system comprising a plurality of robots, each robot including a robot controller (4) for controlling the motions of the robot, and at least one of safety sensor (2a-d) configured to detect hazardous situations in the vicinity of the robots and to produce sensor data. The system comprises an information sharing device (12) connected to the at least one safety sensor and to the robot controllers. The information sharing device is configured to distribute sensor data from the at least one safety sensor to the robot controllers. Each of the robot controllers is allowed to receive sensor data from the at least one safety sensor, and comprises a safety logic unit (14) configured to generate safety commands based on sensor data from the at least one safety sensor.
