The Voice-Activated R2-D2 at Hammacher Schlemmer www.hammacher.com/publish/72698.asp This motorized replica of the headstrong little droid from the Star Wars films responds to voice commands, navigates rooms and hallways, and makes any home feel like it has been transported to a galaxy far, far away. R2 obeys more than 40 voice commands (Turn around! Move forward two units!) and he plays games like tag, using an infra-red sensor to search for people in a room. His sensor helps him follow behind you, or it can be set to detect motion, turning R2 into a room sentry that sounds an alarm when a secured area is invaded. R2s lights, swiveling dome top, and distinctive happy and sad sounds faithfully mimic the real thing, right down to his occasional bad mood. (A simple command of, R2, behave yourself! snaps him out of it.) R2 can also replay sounds and dialog from Star Wars movies, answer yes-or-no questions, and dance while playing the famed cantina music. Requires four AA batteries and four D batteries (not included). Minor assembly required. Ages 8 and up. 15″ H x 7 1/2″ W x 10 1/2″ L. (6 lbs.) $119.95 – Expected ship date 02/16/2007.
