In June 2007, researchers from Osaka University's Graduate School of Engineering creeped the world out with their introduction of CB2, short for "Child-Robot with Biomimetic Body." Measuring 4 ft. 3 (130 cm) long and weighing 73 lb. (33 kg), CB2 is designed to mimic the motions of a toddler. It responds to sounds and reacts to people by wiggling, changing facial expressions and making mechanical gurgling sounds. Thankfully, this one is still in the labs.
