I designed a real-life Robot Maid. This Robot Maid can sweep, carry light objects, get recipes, give you information, have a conversation, serve as a security camera post, do telepresence, tripod, supervise children, entertain others, and even serve as a temporary lamp. All with your phone, a 3D printer, and a cheap cleaner that's under $25.
