Patent number: 11116377Abstract: A robot polisher has, in a box-shaped body part having a round shape in a plan view, right and left batteries, right and left wheel motors (not shown), and a pair of right and left wheels. The right and left wheel motors are rotationally driven by using the batteries as power supplies. The pair of right and left wheels can be individually rotated forward/backward by the respective wheel motors. On a lower housing, at the front-side lower part of the body part, a pair of right and left brushes are downwardly attached, which rotate in directions opposite to each other during traveling while being in sliding contact with a floor surface.Type: GrantFiled: November 20, 2017Date of Patent: September 14, 2021Assignee: MAKITA CORPORATIONInventors: Masahiko Goto, Kentaro Koura
