Implementation method of enabling mobile robot to perform virtual wall obstacle avoidance through computer client

Abstract

The invention discloses an implementation method of enabling a mobile robot to perform virtual wall obstacle avoidance through a computer client. The implementation method includes the following steps: 1) establishing a connection with a mobile robot through a computer client; 2) utilizing an interface provided by the mobile robot to obtain the information and map transmitted from the mobile robot, and displaying the map on an interactive interface of the computer client; and 3) adding any shape of virtual walls at any specified positions on the map of the interactive interface. The implementation method of enabling a mobile robot to perform virtual wall obstacle avoidance through a computer client is applied to the navigation obstacle avoidance behavior related with the mobile robot, and can add, edit and delete virtual walls on the map of the mobile robot through the computer client. Based on the pure software mode, the implementation method of enabling a mobile robot to perform virtual wall obstacle avoidance through a computer client does not need extra auxiliary equipment to realize virtual wall obstacle avoidance for the mobile robot and limit the moving range of the mobile robot. The implementation method of enabling a mobile robot to perform virtual wall obstacle avoidance through a computer client has the advantages of low cost and high precision, and can flexibly switch or change the position and the shape of the virtual walls according to the specific conditions.

Description

technical field [0001] The invention relates to a method for enabling a mobile robot to avoid obstacles by a virtual wall, in particular to a method for enabling a mobile robot to avoid obstacles by a virtual wall through a computer client. Background technique [0002] Currently, virtual wall implementation technologies mainly include two types: [0003] 1. Active virtual wall: This method uses an active transmitting device, such as transmitting an infrared signal or an ultrasonic signal through a transmitting device (US Pat. The role of the signal area. This scheme has the following deficiencies: [0004] 1) An additional active launch device is required. This device needs to be powered by an external power supply or a battery when it is in use, which not only increases the cost, but also if there is a problem with the power supply, the failure of the launch device will cause the mobile robot to be unable to avoid obstacles on the virtual wall or enter the forbidden area...

AI Technical Summary

Problems solved by technology

[0004] 1) An additional active launch device is required. This device needs to be powered by an external power supply or a battery when in use, which not only increases the cost, but also if there is a problem with the power supply, the failure of the launch device will cause the mobile robot to be unable to avoid obstacles on the virtual wall or enter the forbidden area by mistake.

[0005] 2) If an external power supply is used for power supply, an additional socket is required, and it may affect the normal movement of the mobile robot or cause other abnormal behavior problems due to the power supply line dragging the ground

[0006] 3) If the battery is installed for power supply, it needs to be replaced regularly, which will consume additional manpower and material costs, especially in areas where staff are prohibited from using this solution.

[0007] 4) Infrared light will have a diffusion problem. The farther the distance, the greater the angle error, and it is prone to reflection, falsely triggering the avoidance behavior, and affecting the normal movement of the mobile robot

[0009] 1) The operation is relatively cumbersome. Although it can be cut, it needs to be pasted manually. The two ends are easy to arch, and additional purchase is required, which increases the cost

[0010] 2) Change the indoor environment, affect the appearance, and have problems such as hindering pedestrians from walking

[0011] 3) The magnetic boundary line needs to be laid in advance, and the position of the magnetic boundary line cannot be flexibly changed or canceled in real time, so it is impossible to implement some time-based or different virtual wall obstacle avoidance strategies depending on the situation
