Multi-Robot Coordination

Abstract: 

Demanding industrial applications from cold spraying to additive manufacturing are increasingly deploying multiple robots in a coordinated fashion. For cold spray coating, leading industry deployment involves a dual-robot system, where one robot holds the part and the second robot holds the spray gun to impinge metal powders onto the part. For wire-arc additive manufacturing (WAAM), the welding robot, the positioner, and the metrology inspection robots all need to be coordinated to ensure high-quality end products. This talk will discuss issues and the latest advances that arise in such coordinated operation of multiple industrial robots, including:

  • Overall control architecture integrating sensors and robots from different vendors.
  • Kinematics calibration of multiple robots.
  • Redundancy resolution.
  • Tracking accuracy through motion adaptation and learning

Use case results for cold spraying and WAAM using ABB, FANUC, and Motoman robots will be presented.
