Congrats to Instructables user dttworld for bagging the grand $5,000 prize for the iRobot challenge.

Something tells me dttworld wasn't in need of our help, though, judging by his winning home service 'bot: it can talk, recognize faces, control your TV, water your plants, and even remind grandma to take her pills! Check out more photos and video here. —John Mahoney
