Voice-Activated R2-D2

This motorized little droid from the Star Wars 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 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. Of course this R2-D2 replica would not be complete without the swiveling dome, blinking lights, and indecipherable beeps and boops.
