Disclosed is a cleaning robot including: a driving unit configured to move the cleaning robot; an obstacle sensor configured to sense an obstacle; and a controller configured to reduce, if a distance between the cleaning robot and the obstacle is shorter than or equal to a reference distance, a driving speed of the cleaning robot so that the driving speed of the cleaning robot is lower than a shock absorbing speed when the cleaning robot contacts the obstacle.

Cleaning robot and controlling method thereof

A robot cleaner includes a traveling unit to move a main body, an obstacle sensing unit to sense an obstacle, a light reception unit to receive modulated light according to a control command of a user, and a controller to control the traveling unit so that the main body traces a light spot formed by the light. If an obstacle is detected, the controller controls the traveling unit such that the main body traces an outline of the obstacle according to the light spot position and the obstacle position.

Robot cleaner and method for controlling the same

A robot cleaner is provided. The robot cleaner includes a main body forming an exterior; a floor detection sensor for detecting a distance from the main body to a floor surface; a tilt sensor for detecting inclination of the main body; and a controller for determining whether there is a protruding part that protrudes from a floor surface in a running path of the main body, based on a first sensor value output by the floor detection sensor and a second sensor value output by the tilt sensor. In accordance with embodiments of the present disclosure, a robot cleaner may properly move around and perform vacuuming by taking into account conditions of a floor surface. It may also smoothly climb over a doorsill and dynamically change its running pattern based on the presence/absence and position of an obstacle in climbing the doorsill.
