AGI Hand v2

The hand of Kova K2

A tendon-driven robot hand. Tendons run from each finger through the wrist to six smart servos in the forearm module, the layout the 1X NEO hand uses. On Kova K2 the hand is scaled 1.23×, while the servos and spools stay real size.

On Kova K2

Scaled 1.23× for a 2.16 m robot.

On K2 the hand's shells are scaled 1.23× and finished dark, so its length is about 10.8 % of K2's height. Because the servos stay the same, bigger fingers mean longer levers and a lighter grip than the full-size hand.
