Abstract

A robot cleaner comprising: a body; and a sensor protruding from a top surface of the body, wherein the body comprises a protrusion positioned forward of the sensor relative to a forward driving direction of the robot cleaner, the protrusion extending to a height that is at least equal to the height of the sensor.

Claims

1. A robot cleaner comprising:

a body; and

a sensor protruding from a top surface of the body,

wherein the body comprises a protrusion positioned forward of the sensor relative to a forward driving direction of the robot cleaner, the protrusion extending to a height that is at least equal to the height of the sensor.

2. The robot cleaner of claim 1, wherein the protrusion is located on a front portion of the body, the front portion being adjacent to a front edge of the body.

3. The robot cleaner of claim 2, wherein the front portion is downwardly sloped towards the front edge of the body, and the protrusion has a forward-facing edge that extends vertically from the sloped front portion.

4. The robot cleaner of claim 3, wherein the protrusion comprises two stages, a lower stage extending to a height that is at least equal to the height of the top surface of the body, and an upper stage extending to a height that is at least equal to the height of the sensor.

5. The robot cleaner of claim 4, wherein the forward facing edge of the upper stage is positioned behind the forward-facing edge of the lower stage.

6. The robot cleaner of claim 1, wherein the sensor is one of an infra-red sensor assembly, a laser distance sensor assembly and a camera assembly.

7. The robot cleaner of claim 6, wherein the camera assembly is a panoramic annular lens camera which comprises a dome-shaped lens protruding from the top surface of the body.

8. The robot cleaner of claim 1, wherein the body comprises a separating apparatus part that is removable from the remainder of the body and the protrusion is provided on the separating apparatus part.
