IRT or Innovative Response Technologies has produced a robot capable of cleaning. With 3D vision AR wheels easily around obstacles.
Moping the kitchen, clearing the table, loading the dish washer, and doing the laundry, should all be on your list of chores to do until AR takes over.
Weighing in a 130kg it stands 1.5m. The project aims to have a model in mass production in 10 to 20 years’ time, retailing for approximately $10,000 USD each. By that time, battery technology should be significantly improved.
