NAO is the most used humanoid robot for academic purposes worldwide. Aldebaran Robotics has chosen to make NAO's technology available to any higher education program. Fully interactive, fun and permanently evolving, NAO is a standard platform for teaching students of all levels.
Complete with a user-friendly programming environment, students and teachers can use at any programming level. It is really easy to start working on NAO, and our educational kits will get you teaching with NAO in no time !
From simple visual programming to elaborate embedded modules, the versatility of NAO and his programming environment enables users to explore a wide variety of subjects at whatever level of programming complexity and experience.
The scheme on the left 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.
