Mechanism of the robot


The robots have 14, 21 or 25 degrees of freedom; an inertial measurement unit with accelerometer, gyrometer and four ultrasonic sensors that provide Nao with stability and positioning in space. The legs include eight strength sensing resistors and two stops. The robot also has a multimedia system based on Linux, including four microphones (for speech recognition and sound localization), two speakers (for text-to-speech synthesis) and two high-definition cameras (for artificial vision, as facial and shape recognition). It also comes with a software package that includes a graphical programming tool, a simulation software and a software development kit.
