An automatic working system, a turning method thereof, and a self-moving device. When the self-moving device reaches a boundary, a control module controls a movement module to turn to leave the boundary. In addition, the control module may control, based on coverage values corresponding to each movement range when the self-moving device reaches the boundary, the movement module to turn to a movement range with a coverage value that meets a preset requirement.

Automatic work system and turning method therefor, and self-moving device

A outdoor robot includes an execution apparatus and an execution motor for driving the execution apparatus to perform a work task. The control method includes: obtaining a load parameter of the execution motor during running of the outdoor robot; calculating a change rate parameter of a load; and when it is determined that the change rate parameter of the load represents that the load increases and the change rate parameter of the load exceeds a preset threshold range, braking running of the execution apparatus.
