Abstract

The invention provides an obstacle map creation method and system, a robot and a readable storage medium. The method comprises the steps: driving a walking robot to walk along an outer boundary line from an initial positioning point for the first time under the same rectangular coordinate system of a created grid map, and creating the grid map covering the working area of the walking robot on a working area defined by the outer boundary line along with the walking path of the robot; recording feature marks of the grid units on the outer boundary line in real time; after the walking robot is confirmed to return to the initial positioning point along the outer boundary line, supplementing feature marks corresponding to the remaining grid units after the grid units on the outer boundary lineare removed according to the position relation between the grid units and the outer boundary line; and identifying the feature mark of each grid unit on the grid map to form an obstacle map. The working efficiency of the robot can be improved.

Description

technical field [0001] The invention relates to the field of intelligent control, in particular to a method and system for creating an obstacle map, a robot and a readable storage medium. Background technique [0002] With the continuous advancement of science and technology, various automatic working equipment has begun to slowly enter people's lives, such as: automatic vacuuming robots, automatic lawn mowing robots, etc. This kind of automatic working equipment has a walking device, a working device and an automatic control device, so that the automatic working equipment can walk and perform work automatically within a certain range without people's operation. When the energy storage device of the automatic working equipment has insufficient energy, its Ability to automatically return to the charging station unit to recharge and continue working. [0003] In order to improve the coverage and traversal efficiency of the walking robot, the walking robot needs to establish a...
