If you mate the Lego Excavator Set #42006's claw with two Lego Mindstorms EV3 Motors, you get a very versatile motorized "claw". The EV3 Medium Motor closes around an object, and the EV3 Large Motor lifts the blue arm upwards. As the black claw passes the horizontal position of the blue arm, it locks against the front of the EV3 Medium Motor so that you can "dump" the object easily into a raised bin. One could use a Power Functions Large Motor instead of the EV3 Medium Motor, since the internal clutch on the Mini Linear Actuator will slip when the claw is fully closed.
