Robotic Gripper by Eric Sophie
Eric Sophie's Lego robotic gripper ( www.mocpages.com/moc.php/142970 ) is very versatile. Using Lego Shock Absorbers and rubber, it can grab onto an object. You can change from the stiffest (yellow) Shock Absorber to a softer one with less windings on the spring ( www.brickshelf.com/gallery/dluders/ShockAbsorbers/technic... ). If it is mounted onto a Lego Mindstorms EV3 Medium Motor, the servo motor can control the grabber's movements. The size of the jaws can be altered by using different bent Lego Technic Liftarms. The Lego Digital Designer (LDD) .lxf Building Instructions files are on Bricksafe.
