Embodiment Construction

[0028] The above invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0029] The cleaning method of the cleaning robot aims to rely on the map information perceived by the cleaning robot to guide cleaning, thereby achieving the purpose of improving cleaning efficiency. In this method, there are two ways to generate the map, one is to generate the map while cleaning, and the other is to generate the map before cleaning. The former is suitable for a certain number of rooms or the scene where the position of obstacles in the room changes. , while the latter is more suitable for long-term cleaning of indoor obstacles and fixed scenes. See figure 1 , the cleaning method of the cleaning robot performs the following steps based on the acquired detection data and current pose data:

[0030] 100. Determining the preset point as the origin of the map, acquiring boundary data of a wall or an obstacle close to the wall to gene...

Abstract

The invention provides a cleaning robot and a cleaning method thereby. On the basis of acquired detection data and the current position and gesture data, the method comprises the following steps of: determining a preset point as the original point of a map; acquiring boundary data of a wall or an obstacle near the wall to generate the boundary of the map; performing first ergodic operation in the boundary of the map in a preset ergodic mode; if encountering an isolated obstacle, acquiring position and outline data by surrounding the isolated obstacle; identifying regions which can be cleaned in the map boundary according to the position and outline data and the boundary data; at the same time of or after the first ergodic operation, cleaning according to the preset cleaning mode; identifying the non-cleaning regions in the cleaning regions according to the cleaning route; and then cleaning the non-cleaning regions. Compared with the conventional blind cleaning methods, the cleaning method has the advantage of greatly improving cleaning efficiency.

Description

【Technical field】 [0001] The invention relates to a robot, in particular to a cleaning robot and a cleaning method thereof. 【Background technique】 [0002] At present, most cleaning robots use the straight-line cleaning method. If they cannot go straight, they randomly turn at an angle and continue straight. This method has a simple algorithm and a simple hardware structure, but the efficiency is relatively low. Relevant data show that random programming can usually cover 65% of the cleaning area in the first pass, 85% in the second pass, 92% in the third pass, and 98% in the fourth pass, and it can tend to 100% if time is spared. But in fact, due to the cleaning robot's own battery, the power is limited, combined with parameters such as energy consumption and cleaning reset rate, the cleaning efficiency of this blind random cleaning method is unsatisfactory. 【Content of invention】 [0003] Provided are a cleaning robot and a cleaning method capable of improving cleaning ...
