The U of Washington team conducted their study on three of the more common household robots available today, with the goal of looking toward a future when more widely-available, more sophisticated robots take residence in our homes. While it all sounds a bit sci-fi, think about the many ways you can already remotely interact with objects inside your home. Both TiVo and Slingbox let you control your television's DVR from afar, and many homes allow residents to control the lighting, air conditioning, and even door locks without being physically present. Implementation of the smart grid will only increase this remote control capacity. While the idea that some malicious hacker would break into your DVR to cancel your weekly recording of Gossip Girl sounds far-fetched, factor in a mobile robot equipped with camera, microphone, and "hands," and the scenario becomes a bit more frightening.
