I invented a home healthcare robot companion for elderly people who live independently. It would talk and keep them company, play memory/exercise games, remind them to take meds and other forgotten stuff, would have a camera so family members can check in and talk/see them 24/7, it would call 911 and roll video if there was a fall or a code word, maybe some heat sensors to detect if the oven was on, a roomba so it can vacuum as it moves, maybe some type of connectivity to an entertainment system so it can play music/movies/tv with just voice commands. It's a pretty kick ass robot.
