AI Technical Summary

Technical Problem

The existing sweeping robots have a long collision detection time, resulting in low obstacle avoidance performance and easy damage to items.

Method used

The short window detection method is adopted to obtain the collision signal collected by the collision sensor, and to collect multiple data points on the target signal using the trigger edge detection technology to generate collision detection information without the need for a complete collision duration. The appropriate window length is selected for collision detection based on the movement speed.

Benefits of technology

It shortens the collision detection time, improves the collision detection speed and efficiency, enhances obstacle avoidance performance, and reduces the risk of item damage.

Abstract

The invention relates to the technical field of robots, and discloses a collision detection method, a nonvolatile readable storage medium and a robot. The method comprises the steps that a collision signal collected by a collision sensor is obtained, a target signal is determined according to the collision signal, multiple data points are collected on the target signal according to a first preset window length, the first preset window length is smaller than the collision duration of the target signal, and trigger edge detection operation is executed according to the multiple data points to generate collision detection information. According to the embodiment, a target signal with complete collision duration does not need to be taken for collision detection, a plurality of data points are collected in the target signal in a short window mode for collision detection, the first preset window length of the short window mode is smaller than the collision duration of the target signal, collision detection can be carried out more quickly, the collision response time is shortened, and the collision detection efficiency is improved. And the detection efficiency is high. According to the embodiment, collision detection is carried out in a trigger edge detection mode, and the collision detection speed and efficiency can be improved.
