[0043]Example one
[0044]Seefigure 1 , Is a schematic flowchart of the robot collision detection method provided by the first embodiment of the present invention. For ease of description, only the parts related to the embodiment of the present invention are shown. The robot collision detection method includes:
[0045]Step S10, real-time detection of the motor speed of the robot walking motor in the current working state;
[0046]Among them, in an embodiment of the present invention, the robot collision detection method is applied to a robot. Specifically, in this embodiment, it is applied to a lawnmower robot, where the lawnmower robot realizes movement and mowing operations through a motor drive. Specifically, In this embodiment, the mowing robot realizes movement by driving a walking motor. At the same time, in order to prevent damage to the motor caused by overcurrent, the robot motor control design generally has a current limiting module to achieve current limiting protection when the...
