Some people think about a robot roaming a normal house, but it is possible to have a robot room that humans stay out of while the robot is active. Cooking is dangerous and maybe you don't want humans in the room while the robot is cooking. In addition to cooking the robot would have to know how to use a fire extinguisher. It could order grocery delivery. This could be a weight loss tool, because the robot could calculate calories. The same thing could be done with the laundry room.
