Abstract

The invention is suitable for the technical field of robots, and provides a robot collision detection method and device and a robot. The method comprises the steps: detecting the motor rotating speedof a robot walking motor in a current working state in real time; judging whether the motor rotating speed is smaller than the set proportion of the set rotating speed or whether the change rate between the motor rotating speed and the previous motor rotating speed detected at the previous moment is greater than the preset change rate or not; and if yes, it is determined that the robot collides currently. According to the robot collision detection method provided by the invention, the problems of high cost and complex design caused by collision detection in the prior art are solved.

Description

technical field

[0001] The invention belongs to the technical field of robots, and in particular relates to a robot collision detection method, device and robot. Background technique

[0002] Autonomous or robotic powered tools such as robotic lawn mowers are becoming more and more popular. In a typical application, a work area such as a garden, a lawn mowing robot may not know that it collides with many stationary or movable objects. Collision detection is therefore necessary to be able to keep the lawnmowing robot on the job alert to adapt its operation when a collision is detected, thus avoiding the robot simply stopping in front of an object by trying to push through it. Also, from a safety point of view it is important to detect if the robot is lifted so that operating members or implements such as the rotary knives of the lawnmower can be switched off to prevent the risk of injury to the operator.

[0003] Lifting and collision detection are typically achieved by arr...
