Navigation method for sweeping robot

Abstract

The invention discloses a navigation method for a sweeping robot. The navigation method comprises the following steps that firstly, an XOY coordinate system is set up for an area to be swept; secondly, the area to be swept is swept by the sweeping robot, the distance from the sweeping robot to front obstacles is measured in real time through an ultrasonic wave by the sweeping robot to decide the locations of the obstacles, meanwhile, the moving trajectory coordinates of the sweeping robot are recorded by the sweeping robot and sent to a PC terminal through an emitter; thirdly, a sweeping robot moving trajectory plan is generated from the moving trajectory coordinates of the sweeping robot by the PC terminal; fourthly, sweeping work is conducted by the sweeping robot according to the sweeping robot moving trajectory plan generated in the third step. The working efficiency of the sweeping robot is improved and the problem of repeated sweeping work conducted by the sweeping robot can not exist through the sweeping robot moving trajectory plan set up in the first time of use.

Description

technical field [0001] The invention relates to the technical field of robot behavior control, in particular to a navigation method for a sweeping robot. Background technique [0002] Today, with the development of science and technology, people's lifestyles have undergone earth-shaking changes, and various high technologies have been used by people in their daily lives. Various smart homes are also emerging. Now people's pace of life is getting faster and faster, the pressure is getting bigger and bigger, and the requirements for smart home are getting higher and higher. [0003] The development direction of the current smart home is more and more deviated from the core of intelligence. Basically, it needs to be controlled artificially through terminal equipment. It does not realize the self-control of the machine, and there is less communication and interaction with people, which is not really intelligent. [0004] Usually, the intelligent sweeping robot is a complex s...

AI Technical Summary

Problems solved by technology

Various problems due to navigation also emerge in endlessly: 1. The existing cleaning robot uses a contact navigation method based on a collision sensor. Since a collision must occur before it can perceive obstacles in front, this navigation method is prone to fragile objects. Collision, resulting in danger or loss

2. It is difficult to establish a global map, which reduces cleaning efficiency, that is, some areas are cleaned repeatedly, while other areas cannot be cleaned

3. Some charging bases are guided and positioned by infrared rays. If there are many things in the house and there are many rooms, it will be easy to get lost

4. Precise positioning cannot be achieved when using the remote control for fixed-point cleaning control

Seriously affected work efficiency
