Multi-modal human-machine interface of a telerobotic system for remote arc welding

摘要

In telerobotic system for remote welding, human-machine interface is one of the most important factor for enhancing capability and efftciency. This paper presents an architecture design of human-machine interface for welding telerobotic system: welding multi-modal human-machine interface. The human-machine interface integrated several control modes, which are namely shared control, teleteaching, supervisory control and local autonomous control. Space mouse, panoramic vision camera and graphics simulation system are also integrated into the human-machine interface for welding teleoperation. Finally, weld seam tracing and welding experiments of U-shape seam are performed by these control modes respectively. The results show that the system has better performance of human-machine interaction and complexity environment welding.
