The versatile humanoid robot Nao caught Gizmag's attention at the 2009 International Robot Exhibition (iREX 2009). What Nao lacks in size, he makes up for in features and capabilities. Nao can see (via two cameras), will react to touch, can surf the Web and can interact with other Naos. He can speak (in English or French, so far) by reading out any file stored locally in his storage space or captured from a website RSS flow. The bot is fitted with an accelerometer and gyrometer so he won't fall down, he's also equipped with two pairs of ultra-sound senders/receivers on his torso that give feedback on several echoes so Nao is aware of obstacles close by and can avoid them.
