Both the human hand and foot represent a triumph of complex engineering.

The hand uses plastic components that are modeled to mimic human bones, with crocheted ligaments, stringy tendons and rubber skin layered on top.

Researchers have successfully created a robotic hand with bones, ligaments and tendons using 3D printing for the first time.

Researchers created a robot hand that is so accurate it has almost the same dexterity as a human hand. That alone is enough to improve the motion capabilities in prosthetics in a way that has ...
