Nao the contortionist. Nao’s 25 degrees of freedom make him very agile. Programming complex movements and genuine choreographies definitely fall within his scope. Each gear motor was specially designed for Nao. Besides the motors, magnetic rotary encoders are fitted to the joints and provide detailed information on their angle. The servomechanism on the DSpic occurs every millisecond and the joint data (position and power) is fed back to the central processor every 10 ms (Geode at 500 MHz)

Nao's hands Both of Nao’s hands have three interdependent fingers forming a pincer that can seize and lift small objects. The finger and wrist motors are reversible. Nao can carry up to about 300 g (one bottle) using both hands.
