Cooperative and Independent Control of Multiple Robots with Common Controlled Elements (Station-Twin Cooperative Robot System)

摘要

Outline of station-twin cooperative robot system is as described above. High precision of 0.34 mm is noteworthy. The reason of the high accuracy is elimination of follow-up delay on the slave side controlling the robot position data by use of internal bus in real-time. In practical welding with the station-twin cooperative robot operation, high quality welding was achieved. Since a single controller governs both robots and the positioner, all the robots can be stopped in an emergency.
