Device and method for robot collision detection

Abstract

The present invention provides a device and a method for robot collision detection. The device comprises a light emitting module, at least one light sensor, a light identification module and a processing module. The light emitting module is used for emitting the light to the at least one light sensor. Each light sensor is arranged on the surface of the robot and is used for reflecting the received light to the light recognition module according to the own deformation amount thereof. The optical recognition module is used for recognizing the wavelength of the reflected light. The processing module is used for determining one light sensor for each reflected light to belong to, comparing the wavelength of the reflected light of each light sensor with the original wavelength of the reflected light of the light sensor, and determining one light sensor with the wavelength of the reflected light thereof to be changed. According to the location of the above light sensor with the wavelength of the reflected light thereof to be changed, the collision location of the robot is determined. According to the technical scheme of the invention, the specific location of the collision accident of the robot can be determined.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a device and method for robot collision detection. Background technique [0002] With the continuous development and progress of industrial automation technology, robots are widely used in industrial production and daily life to replace manual labor to provide precise operations or work in harsh environments. During the use of the robot, the interaction between the robot and the user often occurs. During the operation of the robot, it is likely to collide with the user or other obstacles, causing damage to the robot itself or causing harm to the user. In order to prevent the robot from colliding and causing damage to the robot itself or the user, it is necessary to detect the collision behavior of the robot, and adopt corresponding reaction strategies to avoid the robot colliding or causing greater losses after the collision. [0003] At present, the method of rob...

Problems solved by technology

[0004] In view of the prior art method of detecting robot collisions, comparing the torque or current obtained by the sensor with the standard torque or current of the robot can only determine whether the robot has collided, but cannot determine the specific location of the collision on the robot
