## Motor specifications

Nao® is equipped with two different motor types with the following characteristics:

## Kinematics

The scheme above presents all the robot’s axes. Together, these axes allow 25 degrees of freedom, which when coupled with the inertial sensor, the force sensitive resistors, the Hall effect sensors, the infrared receiver and the sonar sensors, allows Nao® a high level of stability and fluidity in its movements.
