A group of 10 tiny robot cheerleaders. A Japanese electronics company has unveiled
the self-balancing miniatures – who move using gyroscopes to balance on a ball and roll about. Synchronized to their own music, the robots
do little more than dance to the beat. They use four infrared sensors and five ultrasonic
microphones to detect objects even in a completely dark room. The company behind the little guys, Japan’s
Murata Electronics, says that while they put over two years of development into the robots
they don’t plan to actually sell them or use them for anything more than display.
