Household cleaning robot capable of establishing map by self and cleaning method

Abstract

The invention discloses a household cleaning robot capable of establishing a map by self and a cleaning method. The household cleaning robot comprises a casing, a control center arranged in the casing, a power supply module, a storage unit, a camera, a lighting alarm device, an ultrasonic wave sensor, an infrared sensor, a photosensitive sensor, a wireless module and an RFID reader-writer, wherein the ultrasonic wave sensor, the infrared sensor and the photosensitive sensor are respectively connected with the control center, and the wireless module and the RFID reader-writer are connected with the control center. The household cleaning robot further comprises a plurality of RFID labels bonded under the periphery of a wall, wherein the RFID labels are used for recording position coordinate information and are active RFID labels. The cleaning robot can establish the indoor two-dimensional map to achieve the indoor location function and acquire the coordinate points in a room. Walking areas and non-walking areas are marked on the two-dimensional map, so that the cleaning robot can quickly determine a cleaning path and accurately reach a target to be cleaned. To hygienic dead angles which cannot be cleaned, the cleaning robot is manually operated and controlled to automatically store operation and control data. When the hygienic dead angles are cleaned again, the stored operation and control data can be called to clean the target.

Description

technical field [0001] The invention relates to a cleaning robot, in particular to a household cleaning robot with a self-built map and a cleaning method capable of self-built maps, positioning and cleaning targets in two control modes, automatic and wireless manual. Background technique [0002] The cleaning robot is a special robot serving human beings. It can move autonomously in the room and avoid the obstacles in the room. It is mainly engaged in household cleaning and cleaning, which relieves people from the heavy cleaning work. [0003] At present, household cleaning robots mainly include control system, cleaning system, measurement system, power system, etc. Among them, the control system is the core of the whole robot, which can process the data collected by the measurement system and coordinate the work of each system. The cleaning system is used to clean foreign matter, and its cleaning action is controlled by the control center. Each sensor of the measurement sy...

Problems solved by technology

A robot using this method requires a large number of sensors, resulting in high manufacturing costs, many parameters required for positioning, and high processing speed requirements for the control unit.

At the same time, there is a slipping phenomenon between the robot and the ground during the movement process, and the measured travel distance will have errors. This error will accumulate and become larger as the robot’s moving distance increases, eventu
