’World’s strongest’ robotic hand can cut paper, hold eggs — and even play the piano

Researchers have unveiled a robotic hand that can serve drinks, pick up eggs, cut paper with scissors, and even play a few notes on the piano.

The Korea Institute of Machinery & Materials (KIMM) claims that the device offers the world’s strongest grasping force measured against its own weight.

The hand is comprised of four fingers and 16 joints, which are all moved independently by 12 individual motors. This design intends to replicate the movements of human fingers.

Sensors attached to the fingertips, palm and fingers detect contact with objects. When the hand touches the object, the sensors measure the grasping force that’s required to handle it.

The hand can be mounted on a variety of robotic arms. It weighs less than 1 kg but can hold objects of more than three times that weight.
