An anonymous reader writes "Japanese researchers unveiled yesterday a pocket-size telepresence robot called Elfoid. The device, which looks like a little ghost, transmits voice and motion over a 3G network to convey a person's 'presence' to a remote location. It's a creation of Hiroshi Ishiguro, a professor at Osaka University who is known for his lifelike teleoperated androids. The Elfoid has a limited range of motion, but its creators are planning to equip it with mini-actuators so it can imitate the movements of the person on the other end of the line. With vaguely formed features, the device is designed to be a surrogate of people of any age or gender."
