Robot task execution method and apparatus, robot, and storage medium

A robot task execution method, wherein, the robot task execution method comprises:

• acquiring a training trajectory and an environment map in a training mode;
• generating a target region for tasks to be performed by a robot based on the environment map and the training trajectory, wherein, the target region is a maximum envelope region in which the robot can complete the tasks autonomously;
• controlling the robot to traverse the target region until the robot completes the tasks to be performed;
• wherein, the step of generating a target region for tasks to be performed by the robot comprises:
• expanding the training trajectory within the environment map to obtain the maximum envelope region in which the robot can complete the tasks autonomously;
• wherein, the step of expanding the training trajectory within the environment map to obtam the maximum envelope region in which the robot can complete the tasks autonomously comprises:
• importing grid information of M layers of grids on a left side of the training trajectory and N layers of grids on a right side of the training trajectory into a newly established coverage region map, wherein, a one-time coverage width of the robot is equal to M+N+1, M and N are both integers greater than or equal to 1;
• extracting an inner envelope and an outer envelope of a coverage region within the coverage region map, overlaying an inward expandable region of the inner envelope and an outward expandable region of the outer envelope, thereby obtaining the maximum envelope region in which the robot can complete the tasks autonomously.
