Region traversing method and chip of robot and cleaning robot

Abstract

The invention relates to a region traversing method and chip of a robot and a cleaning robot. The method and the chip can improve the cleaning quality of the robot. The region traversing method of therobot comprises the steps that firstly a cleanable range of a grid area is delineated, then planed cleaning is performed in the delineated area, the robot can know the approximate terrain in advanceduring cleaning and can makes a plan in advance, thereby improving the cleaning quality ad efficiency of the robot. For example, it can be known that the robot is ready to reach a physical boundary only through a map without judging the boundary through collisions or other sensors; in addition, some narrower entrances are known in advance during delineation and are not easy to miss in subsequent planned cleaning.

Description

technical field [0001] The invention relates to the field of intelligent robots, in particular to a robot area traversal method, a chip and a cleaning robot. Background technique [0002] There are many kinds of SLAM algorithms, such as those based on laser scanning navigation, and those based on visual navigation. The cost of the former is relatively expensive, and the ordinary ones cost between 300 and 500 yuan. The Xiaomi sweeping robot is also based on this principle. It is relatively low, but the technical threshold is relatively high. At present, there are not many products with visual navigation on the market that do a good job, such as Roomba 980, which has a better effect. However, the above two methods are relatively high in cost. At present, most of the low-cost map navigation solutions on the market are still based on gyroscopes, but only based on gyroscopes, it is very important to achieve accurate maps and high efficiency in path planning and navigation in var...

AI Technical Summary

Problems solved by technology

Generally, these sweeping robots using the slam algorithm directly carry out bow-shaped planning and cleaning. If there is only a small passage in the middle of the area that allows the robot to pass through and enter the other side of the area, the robot is likely to fail due to walking errors. Due to other reasons, the entrance of the channel cannot be effectively detected, and it is mistakenly believed that there is no area to clean on the other side of the area, resulting in missed scanning.
