Cleaning robot and control method thereof

Abstract

The invention discloses a cleaning robot which comprises a walking unit, a control unit, a dust suction unit, a display unit, a voice unit and a collision detection unit, wherein the cleaning robot isprovided with at least one obstacle detection unit for detecting position data of obstacles in a cleaning region; the obstacle detection unit is mounted at the top of a front side of the cleaning robot and is connected with the control unit; the obstacle detection unit comprises a first detection module for detecting whether obstacles exist in front of the cleaning robot or not and a second detection module for detecting whether obstacles exist above the top of the cleaning robot or not. The solution adopted by the invention solves a problem that the conventional cleaning robot cannot detectwhether the obstacles exist on the front side and above the top of the cleaning robot or not at the same time, and solves a problem that a user cannot timely and accurately find the cleaning robot because the cleaning robot is easy to stay in a part of relatively low indoor space region and cannot be automatically recharged.

Description

technical field [0001] The invention relates to the field of smart home, to a cleaning robot, and in particular to a cleaning robot and a control method thereof. Background technique [0002] With the popularization of smart products, more and more people use cleaning robots to replace the cleaning in the manual cleaning room. The existing cleaning robots are mainly divided into two types. Judging and guiding the cleaning robot to move forward in the correct direction, detecting obstacles by setting a collision detection unit on the front side of the cleaning robot, avoiding obstacles to walk to perform indoor cleaning tasks; The laser navigation module is set on the top of the robot to detect indoor obstacles and build an indoor map, so as to guide the cleaning robot to move in the correct direction and avoid obstacles to perform indoor cleaning tasks. [0003] Existing cleaning robots can only detect obstacles in the horizontal direction in the room, but cannot detect whe...

Problems solved by technology

[0007] For this reason, the object of the present invention is to provide a cleaning robot and its control method, which mainly solves the problem that the existing cleaning robot cannot detect whether there is an obstacle in the vertical direction in the cleaning area, that is, it cannot detect whether the top of the cleaning robot is The problem of obstacles; solve the problem that the existing cleaning robot cannot detect whether there are obstacles on the front side and the top of the cleaning robot at the same time; solve the problem that the existing cleaning robot cannot set the corresponding deep cleaning mode or no-sweep cleaning for some cleaning areas The problem of specific cleaning modes such as cleaning mode solves the problem that existing cleaning robots tend to stay in the lower part of the room and cannot autonomously recharge and recharge, and the user cannot find out where the cleaning robot is in the room in a timely and accurate manner.
