This tiny Lego "micro-grabber" uses only 12 parts to attach onto a Lego Mindstorms EV3 Medium Motor.  The small, geared pincers are 24014 "Technic, Arm with Gear 8 Tooth and 1.5L Axle" ( <a href="http://www.bricklink.com/v2/catalog/catalogitem.page?P=24014#T=C&C=86" rel="nofollow">www.bricklink.com/v2/catalog/catalogitem.page?P=24014#T=C...</a>; ) that turn when the black Worm Gear rotates.  The micro-grabber at the top shows optional, black 45590 "Technic, Axle Connector Double Flexible (Rubber)" pieces ( <a href="http://www.bricklink.com/v2/catalog/catalogitem.page?P=45590#T=C" rel="nofollow">www.bricklink.com/v2/catalog/catalogitem.page?P=45590#T=C</a>; ) to keep things from slipping.  To make the pincers longer, one could add Technic Axle Connectors ( <a href="http://www.bricklink.com/v2/catalog/catalogitem.page?P=6538c#T=C" rel="nofollow">www.bricklink.com/v2/catalog/catalogitem.page?P=6538c#T=C</a>; ) to hold Technic Axles.
