The Japanese company Takara -- the folks who brought you the Bow-Lingual dog translation gadget -- is showing a line of robots at the Tokyo international forum that play music and movies, watch the house and track your body fat. Called TERA, an acronym for Takara Entertainment Robot Architecture, the new family of robots, including TERA SECURITY, TERA LIFE and TERA AV robots, is slated for a Spring 2006 release. Tera AV (for audio-visual) plays DVDs and CDs that are loaded into its mouth. Like R2-D2, it has its own built-in projector, as well as speakers, a modem and a built in hard disk. The TERA SECURITY robot keeps watch with its camera eye and special sensors, and sounds an alarm if there's some kind of accident or problem, such as a gas leak or fire. The alarm can be turned off only by a person with a registered fingerprint. The TERA LIFE robot features include has a blood-alcohol sensor, body thermometer, blood pressure sensor and even a fat meter -- presumably to determine if you're an alcoholic, feverish, high-strung fatty.
