Claims18
A mobile robot, comprising:
- a body;
- a rotating plate rotatably installed on the body, the rotating plate including a mop portion attached to a lower surface thereof;
- and
- a rotating ball rotatably installed on the rotating plate, the rotating ball being vertically aligned with a rotating shaft of the rotating plate,
- wherein at least a portion of the rotating ball is positioned below a lower surface of the rotating plate, and
- wherein the mop portion includes a guide hole that receives a portion of the rotating ball, and the guide hole is opened below, such that the rotating ball is exposed to a surface to be cleaned by the mobile robot.

A mobile robot, comprising:
- a body;
- a rotating plate rotatably installed on the body, the rotating plate including a mop portion attached to a lower surface thereof;
- a ball space vertically aligned with a rotation axis of the rotating plate, the ball space defining a space having an opening at a lower end;
- a rotating ball configured to move in a vertical direction inside the ball space;
- and
- an elastic member positioned in the ball space, the elastic member being configured to bias the rotating ball towards the opening of the ball space,
- wherein the mop portion includes a centrally positioned guide hole in which a portion of the rotating ball is received, and the centrally positioned guide hole is opened below, such that the rotating ball is exposed to a surface to be cleaned by the mobile robot.

A mobile robot, comprising:
- a body;
- a rotating plate rotatably installed on the body, the rotating plate including a mop portion attached to a lower surface thereof;
- a ball space vertically aligned with a rotation axis of the rotating plate, the ball space defining a space having an opening at a lower end;
- a rotating ball positioned at least partly in the ball space, wherein the rotating ball is configured to be movable in a vertical direction inside the ball space;
- an elastic member biasing the rotating ball towards the opening of the ball space;
- and
- a caster encoder configured to detect a rotational speed of the rotating ball,
- wherein the mop portion includes a centrally positioned guide hole in which a portion of the rotating ball is received, and the centrally positioned guide hole is opened below, such that the rotating ball is exposed to a surface to be cleaned by the mobile robot.
