Overview

A household robot from the Tokyo startup MW that hangs from the ceiling instead of walking on the floor. A humanoid-style upper body with two arms runs on rails in the ceiling and walls. It folds away into a 'nest' when idle, and a separate MW Cargo carrier on the same rails moves shopping bags, laundry and trash. MW argues that a gantry leaves the floor free, is easier to make safe (it designs to the ISO 13482 personal care robot standard), and can count as a fixed fixture covered by a home loan. The tradeoff, which MW states itself, is less freedom of movement than a humanoid. The prototype was first shown live in Toyosu, Tokyo, on September 10, 2026, installed in a trailer-house test rig. Under teleoperation it sorted pantry items and folded a hand towel taken from a dryer, but struggled with a T-shirt. It ran at about 1/20 of human speed, and MW aims for half human speed within three years. An autonomous demo house in Yokohama is planned for September 2027. Compare floor-based home robots such as LG CLOiD.
