From the cool toys department at Sony comes SDR-4X, a 23-inch tall humanoid robot equipped with face recognition, stereoscopic vision, a 60,000 word vocabulary, and some other interesting features.  It reportedly can walk on uneven surfaces such as carpeting, tumble without breaking, and get back up by itself.  It also carries the price tag of a luxury car, so I don’t expect to be getting one for my birthday.  But, damn, the thing’s cool!
