US 2019/0155299 A1 · MOVING ROBOT AND CONTROL METHOD THEREOF

Abstract

Disclosed are a moving robot and a control method thereof, and the moving robot comprises a floor sensing unit comprised of a plurality of transmitters, for which different sensing distances are set, and a single receiver, and, since a floor state is sensed using a plurality of sensors, it is possible to sense a normal floor states, an obstacle or a cliff present on a floor, and a long-distance state at a distance farther than the normal floor state, thereby preventing wrong sensing of a cliff due to an obstacle, and, since whether to keep traveling is set depending on the obstacle and a traveling speed is controlled, even an area previously not allowed to enter due to the wrong sensing may be cleaned and therefore a cleaning area may be increased.

Dependent claims

A moving robot comprising:

a movable main body;
a travel drive unit configured to move the main body;
a floor sensing unit comprising a plurality of transmitters for transmitting signals set with different sensing distances toward a floor and a single receiver for receiving any one of the signals transmitted from the plurality of transmitters, and configured to sense a state of the floor;
and
a controller configured to control the travel drive unit by changing a travel setting in accordance with a floor sensing signal received from the floor sensing unit,
wherein the floor sensing unit is further configured to, when the signals are respectively transmitted from the plurality of transmitters toward the floor, determine the state of the floor by calculating a distance from a bottom surface of the main body to the floor in response to a signal reflected and then incident on the receiver.
