Embodiment Construction

[0021] The content of the present invention will be described below in conjunction with specific embodiments.

[0022] Such as figure 1 As shown, it is a structural schematic diagram of a robot collision avoidance system based on sonar detection.

[0023] A robot collision avoidance system based on sonar detection, comprising the following steps:

[0024] 1) Install a sonar detector on the robot, and collect the robot's running direction information through the sonar detector;

[0025] 2) Calculate the distance between the robot and the object through the collected information, and transmit the information of the sonar detector to the anti-collision controller;

[0026] 3) The anti-collision controller judges whether it is a dangerous distance according to the received distance, and sends out an instruction for the next step according to the set threshold value. If the dangerous distance is not reached, the robot operates normally, and when the dangerous distance is reached,...

Abstract

The invention relates to a robot safety designing method, in particular to a robot anticollision system based on sonar detection. A sonar detection device is arranged at a key position of a robot, and protection action is performed within a set threshold value range in a stepped manner. The robot anticollision system has the advantages that compared with a collision algorithm utilizing signals like motor torque and angle to detect collision events and responding, at the time, collision occurs already, and damage is caused already; sonar technology is introduced, response is made before collision occurs to prevent the collision events; compared with a scheme utilizing a visual system to prevent collision, a current visual system is greatly influenced by light, so that accuracy in detection of the collision events is difficult to realize, and the sonar technology is relatively mature; effect of reliably preventing the collision is realized through a detection mode optimizing conventional similar schemes.

Description

technical field [0001] The invention relates to a robot safety design method, in particular to a robot collision avoidance system based on sonar detection, in which a sonar detection device is installed at a key part of the robot, and protection actions are performed in stages within a set threshold range. Background technique [0002] With the continuous development of computer technology in the direction of intelligence and the continuous expansion and deepening of robot application fields, industrial robots have become a high-tech industry, which has played a huge role in the level of industrial automation and will play an increasingly important role in future production and social development. more important role. In general, robots are widely used in electronic products, such as the automotive industry, plastics industry, pharmaceutical industry, and food industry, to complete operations such as handling, assembly, spraying, and welding to replace manual operations, the...
