Problems solved by technology

[0003] Existing obstacle avoidance schemes have the following disadvantages: first, obstacles can only be detected at the height plane where the sensor is located. For situations such as a four-legged table, assuming that the height of the sensor is 30 cm and the height of the table is 60 cm, the sensor cannot The detection of obstacles will eventually cause the robot to hit the table; second, obstacles can only be detected in the direction where the sensor is installed. If there is no sensor behind the robot, the backward movement will cause the robot to hit the obstacle

Embodiment Construction

[0062] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0063] The invention provides a robot obstacle avoidance method.

[0064] refer to figure 1 , figure 1 It is a schematic flowchart of an embodiment of the robot obstacle avoidance method of the present invention.

[0065] In one embodiment, the robot obstacle avoidance method includes:

[0066] Step S10, the obstacle avoidance control system of the robot obtains the robot's current positioning data (such as indoor position, posture, etc.) The position data of the obstacle determines whether there is an obstacle whose distance from the current positi...

Abstract

The invention discloses an obstacle avoidance control system and method for a robot. The method includes: acquiring the current positioning data of the robot, and determining the current positioning position to Whether there is an obstacle in the target position path whose distance from the current positioning position is less than the preset distance; and the pre-determined 3D model of the obstacle, calculate the shortest distance between the robot and the obstacle; according to the obtained positioning data, the calculated shortest distance and the 3D model of the obstacle, calculate the current direction the robot should move, according to The calculated motion direction controls the motion pose of the robot to avoid obstacles. The invention can effectively control the robot to avoid obstacles.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a robot obstacle avoidance control system and method. Background technique [0002] At present, autonomous mobile robots can be widely used in many scenarios, such as serving as a tour guide in an exhibition hall, leading visitors from one exhibition area to another; serving in restaurants, actively welcoming guests and leading them to order food on empty seats ; Guidance and patrol work in public places, moving along the route set by the program, someone needs help to stop and answer questions, etc. In these scenarios, how to prevent the robot from colliding with obstacles in the environment is an important technical issue. At present, autonomous mobile robots rely on their own sensors to locate and avoid obstacles. The usual obstacle avoidance solution in the industry is to install proximity sensors (such as ultrasonic, infrared, laser, etc.) on the robot. distance (for exa...
