Functioning Cyborg Arm Built From LEGO Mindstorms

LEGO builder Diavo Voltaggio showed off the latest in a number of cyborg arms he’s built using a Mindstorms set during an interview with YouTube series Beyond the Brick at the BrickFair Virginia conference in Chantilly, VA. The Mark VI arm has four buttons that control four motors, letting him open and close the hand. There are also a number of LED lights for visual effect and a built-in smartphone holder.

The phone is just for fun. My best friend’s on the other side of the convention, and we’ve been texting back and forth. Can’t miss a message, right?
