The essential ingredient is a separate servo motor for each joint in the hand, which allows each joint to bend equally well backward and forward.

How do you make a robot hand? If you are [Robimek], you start with some plastic spiral tubing, some servo motors, and some fishing line. Oh, and you also need an old glove.

Columbia Engineering researchers demonstrated a highly dexterous robot hand, one that combines an advanced sense of touch with motor learning algorithms in order to achieve a high level of ...

What’s more, the hand could point the way to better designs for robot limbs. Most artificial limbs require complex mechanisms to control all their moving parts, but that might be overkill.
