At Automate 2019, Robotiq announced new entries to their product offering, including two suction cup gripper tools. ePick is a suction gripper that uses electric power from the wrist of the robot to power the suction cup, eliminating the need for an external air line. AirPick does need an air line but is modular and reconfigurable to suit different applications. Find out more about those tools here.
The company also demonstrated a rotary sanding and finishing tool which uses force sensing to apply constant pressure to the workpiece.
