Need a Hand?

Robotic Hand

Fortunately, the opportunity to make ham-fisted puns is far from the coolest thing about this project. It has 11 degrees of freedom, and each joint sports roughly the same range of motion as its flesh-and-blood counterpart. Articulation is achieved by 10 standard hobby servos pulling on steel wires that run to the finger joints; plus one servo to rotate the thumb.It doesn’t end there, though. No way. This guy built a contrller for the hand, and it looks like… Well it looks like something you’d have seen in Popular Science magazine in the 1980’s with a caption that read, “You will use something like this… IN THE FUTURE.” And here it is:

Looking like a Nintendo Power Glove on steroids, the controller has a potentiometer rigged to each joint, and everything is translated to servo control signals by an Atmel microcontroller.To see more pictures of these finely crafted pieces of hardware, follow this link.
