Problems solved by technology

[0003] However, the current robot technology is not mature enough, there are still many problems
For example, when multiple mobile robots are running in the same connected space, the problem of meeting cannot be avoided, especially in a narrow space, the robots will be deadlocked or blocked.

[0024] Please refer to image 3 , image 3 It is a flow chart of a robot path interference detection method provided by a preferred embodiment of the present invention. The above robot path interference detection method is applied to figure 1 Robot path interference detection system in . The above robot path interference detection method includes the following steps:

[0025] Step S101 , when the first robot detects the second robot, send a detection instruction to the server 100 .

[0026] In the embodiment of the present invention, the first robot may be provided with a perception unit (such as an infrared probe, an image recognition unit) for real-time perception of obstacles in the surrounding environment during operation. Corresponding to the first robot, other robots 200 also belong to obstacles. When the first robot perceives that there is an obstacle nearby, it is judged whether it is the second robot by extracting the size or identification feature of the recogni...

Embodiment approach

[0043] As an implementation manner, the following algorithm may be used to implement step S103, specifically:

[0044]

[0045] Among them, l jk Represents that the sequence number on the first displacement path is i j The sequence number on the grid path point and the second displacement path is i k The distance length value of the raster path point, m js is the serial number corresponding to the first target grid path point corresponding to the first position information on the first displacement path, m ks is the sequence number corresponding to the second target grid path point corresponding to the second position information on the second displacement path. i j The value of can be not less than m js and not greater than m js +min(m j -m js ,m k -m ks ), and m j is the total number of grid path points corresponding to the first displacement path; i k The value of can be not less than m ks and not greater than m ks +min(m j -m js ,m k -m ks ), and m k ...

[0051] A robot path interference detection system provided by a preferred embodiment of the present invention includes a server 100, a first robot and a second robot, and the server 100 is connected to the first robot and the second robot by communication respectively.

[0052] The first robot is configured to send a detection instruction to the server 100 when detecting the second robot.

[0053] The server 100 is configured to respectively acquire a first remaining path of the first robot and a second remaining path of the second robot according to the detection instruction.

[0054] Preferably, a first displacement path composed of multiple grid path points is pre-generated in the first robot; a second displacement path composed of multiple grid path points is pre-generated in the second robot. Obtain the first displacement path and the second displacement path respectively, receive the current first position information of the first robot and the current second position in...

Abstract

The invention provides a robot path interference detection method and system. The robot path interference detection method comprises the following steps: sending a detection instruction to a server when a first robot detects a second robot; respectively acquiring a first residual path of the first robot and a second residual path of a second robot by the server according to the detection instruction; comparing the first residual path with the second residual path to acquire a comparison result; and judging whether path interference exists between the first robot and the second robot accordingto the comparison result. Therefore, the operation of judging whether the first robot and the second robot judged and sensed by the first robot can meet is realized without complexly analyzing whetherthe tracks are parallel or not; the judgment method is more efficient and simple, so that the robot can take measures in advance to avoid the meeting.

Description

technical field [0001] The present invention relates to the technical field of robot movement, in particular to a robot path interference detection method and system. Background technique [0002] With the advancement of technology, robots are no longer just characters in technology movies, but actually appear in real life. A robot is a machine device that performs work automatically. It can accept human command, run pre-programmed programs, and act according to principles formulated with artificial intelligence technology. It can undertake a lot of work in life and save labor costs. [0003] However, the current robot technology is not mature enough, and there are still many problems. For example, when multiple mobile robots are running in the same connected space, the problem of meeting cannot be avoided, especially in a narrow space, the robots will be deadlocked or blocked. Contents of the invention [0004] The purpose of the present invention is to provide a robo...
