4M Robotic Hand Instructions

D. OPERATION
Hold the Robotic Hand with its flat face (i.e. the back of the hand) facing up. Grasp the
frame with your right hand, with its palm facing down. Put your first three fingers into the
pull rings, holding the frame with your thumb and little finger. Pull on the rings to make the
Robotic Handʼs fingers and thumb bend.
Can you grip your other hand? Can you pick up an object? Put a glove onto the Robotic
Hand, and find a shirt or other top with a sleeve long enough to hide your real hand when
you are holding the Robotic Handʼs frame. Shake hands with your friends with your unique
Robotic Hand. They will be amazed!
E. HOW IT WORKS
When you pull on one of the rings, the strings shorten the inside of the fingers attached to
the ring. The outside of the finger remains the same length, so the shortening makes the
fingers bend inwards.
F. FUN FACTS
• Industrial robots work in factories, moving and joining parts of things being made. They
have grippers for picking up objects, with two or three fingers that can open and close.
• In robot hands, the fingers are moved by tiny motors, hydraulic rams or air-powered
artificial ʻmusclesʼ.
• Robot researchers have built robot hands that look like human hands and have fingers
that move like human fingers. They are very complicated machines, using many joints and
a dozen or more motors.
• Human-like robot hands could be used in humanoid robots.
• Robot hands have pressure sensors in the finger tips. When the fingers are gripping an
object, the sensors prevent the fingers from squashing the object.
• In human hands, thin tendons running inside the fingers make the fingers bend. The
tendons are pulled by muscles in the forearm.
• Prosthetic hands are for people who have lost a hand or arm in an accident. They are like
robot hands, but they are controlled by electrical signals from the remaining muscles in the
arm.
