Problems solved by technology

However, these methods are all control strategies when obstacles appear on the planned route. For obstacles that are not on the route, the robot will not have any response. There will be a problem that the obstacle is already very close to the robot. But it is not on the route, the robot will maintain the original speed (possibly high) and pass directly, which will have certain safety hazards for the dynamic obstacles (such as people, etc.) next to it

Abstract

The invention discloses a safe control method and system for a mobile robot, wherein the method comprises the following steps: S100) obtaining the working environment map information of a robot; S200) obtaining the current position information about the robot's travel in the working environment map information; S300) using the current position information as a reference to obtain the position information of its surrounding obstacles; and S400) controlling the travel mode of the robot based on the position information of its surrounding obstacles. The method and the system are designed with the object of finding out the obstacles that are closest to the robot in real time and making the robot respond differently to the obstacles so the robot is more like a human in terms of logic thinking and becomes more intelligent with the result that the working safety of the robot is increased.

Description

technical field [0001] The invention relates to the field of robot intelligent control, in particular to a method and system for safety control of a mobile robot. Background technique [0002] In recent years, with the rapid development of mobile robots, people have higher and higher requirements for the safety of robots. Therefore, when the robot encounters obstacles, there are more and more delicate control strategies, which will be the future development. It is also an important guarantee for the safety and intelligence of robots. [0003] The traditional mobile robot adopts the control strategy of avoiding obstacles, but this strategy is too rigid. In recent years, there have also been some corresponding control strategies based on the state of obstacles, such as waiting to stop, blocking obstacles, etc., which enrich the control strategies when the robot encounters obstacles. However, these methods are all control strategies when obstacles appear on the planned route....
