Embodiment Construction

[0084] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0085] When the sweeping robot is cleaning, it will generally use the charging stand or some other point as the origin to start cleaning in a bow shape. The so-called bow-shaped cleaning means that when the robot travels straight along the straight-line path to the turning point, it turns to 90° and travels to a certain width, and then turns to 90° so that the current direction of travel is opposite to the direction of the original straight-line path, and then continues to move to next turning point. Because the trajectory of the robot in this way is similar to a bow, it is called bow-shaped cleaning. The turning point is a position point when the robot reaches the boundary of the area or detects an obstacle such as a wall that meets the turning condition.

[0086] Such as figure 1 As shown, the line with the arrow indicates the trajectory of t...

Abstract

The invention relates to a sweeping robot supplementary sweeping method and a chip. The method comprises the steps that entrance reference points of the boundary of each entrance of a swept region and an unswept region are selected preferentially, the best entrance point is determined, one point is selected from the best entrance point according to entrance selection conditions as a sweeping starting point, and region sweeping is performed on the basis of the preset sweeping conditions. According to the supplementary sweeping method, no any marking position point needs to be made, only endpoints of the entrance boundaries of the sweeping region and the unswept region in a raster map are adopted as entrance reference points for performing preferential selection, even if the shape of the unswept region is complex, the sweeping starting point of the unswept region can be more objectively, more flexibly and more accurately determined just by analyzing and judging the boundaries and selecting the best entrance point, and therefore the most suitable unswept region is preferentially swept. Meanwhile, according to the preset sweeping conditions, the region is swept, the problem that omitted sweeping caused by the existing mode that a zigzagged shaped sweeping is performed simply from the marked position point can be avoided, and sweeping comprehensiveness and integrity are ensured.

Description

technical field [0001] The invention relates to the field of robots, in particular to a sweeping method and a chip for a sweeping robot. Background technique [0002] The existing sweeping robot, in the conventional bow-shaped cleaning process, will make a mark position point at the boundary of the unswept area, and then find out all the unswept areas by searching the grid map in the process of checking for leaks. The marked position point of the area, and then select the best position point with the closest distance to the current position through the path search algorithm, and finally navigate to the best position point, it is preferable to clean the area, after cleaning the area, select The next best location point is the closest to clean, and so on, until all uncleaned areas are cleaned. Among them, the distance between the best location point and the current location is not a straight-line distance, but an accessible path distance. The robot will search all the paths t...
