These dancing robots were made by a french company called Aldebaran Robotics and this video was filmed on a Shanghai Expo. Since 2007 these robots are used in the Robot Soccer World Cup. The Nao (the name of these cute robots) is a programmable robot with a height of 58 cm and a weight of 4.3 kg, it has a Linux Operating System and a x86 AMD 500 MHz processor. It has four mics, 2 cameras and 2 speakers, it does text-to-speech synthesis (in other words it can talk and read) and it also has shape and facial recognition abilities, quite a robot! Also Aldebaran Robotics announced that they're going to release Nao's source code by the end of the year. Personally I love robots, even if they're gonna conquer the world sooner or later. That's why I wanted to share this, enjoy!
