From Wired/GadgetLab:
The Nao robot developed by Aldebaran Robotics weighs about 9.5 lbs and is about 23 inches tall. The robot comes with x86 AMD Geocode 500 Mhz CPU, 2 GB flash memory, two speakers, vision processing capabilities, Wi-fi connectivity and ethernet port. It has 25 degrees of freedom, which means it can do a lot more than just tilt is head, look right, left and take a few steps –which is the ability being showcased with the dancing.
