Robot arms, articulated, collaborative, SCARA, delta and gantry robots, mobile manipulators, general robot cells and machine-tending systems. Includes educational and demonstration robots, robot-specific controllers, teach pendants, grippers, tool changers, interfaces and replacement parts. A complete packaging, palletising, welding or inspection machine follows its purchased function where that function is established; a robot platform does not change family merely because it can perform that task.
