Aiming at problem of low precision of workpieces grasping and placing of monocular vision robot

propose hybrid cameras visual servo system based on position

mode combining Eye-in-hand and Eye-to-hand camera is used

establish hybrid cameras visual robot system to realize accurate placement of workpiece. Eye-inhand camera is used to realize workpiece orientation and grasping. Eye-to-hand camera is used to evaluates pixel coordinates difference of center line between mechanical gripper and workpiece to ensure that the workpiece is placed in precise desire location. Experimental results show that this hybrid cameras visual servo robot can place workpiece in specified coordinates accurately.
