Problems solved by technology

[0002] With the development of science and technology, cleaning robots with certain functions have gradually entered the home and office environment, reducing the labor burden of people. In the existing technology, when cleaning the room, the cleaning robot basically uses the collision method Make direction adjustments. Although there is a buffer structure around the cleaning robot, the cleaning robot will also be damaged as the use time increases, and the direction adjustment through collision may also damage the furniture, etc.
[0003] For example, the Chinese invention patent application whose application number is 201410668350.5 discloses a cleaning mode of a cleaning robot, specifically: the cleaning robot includes the following steps in sequence in the cleaning mode: a. The step of roughly detecting and confirming that it has entered an open area; b. the step of the cleaning robot performing full-coverage cleaning in the open area; when the cleaning robot performs full-coverage cleaning, its path coverage density is greater than that of the cleaning robot during rough detection The path coverage density; c. The step of exiting the cleaning mode after the cleaning robot meets the system preset conditions, but it does not solve the method for the cleaning robot to avoid obstacles
[0004] Another example is the Chinese invention patent with the application number of 201310071351.7, which discloses a cleaning method for a cleaning robot extended along the side navigation direction, which specifically includes: the cleaning robot travels along the outer wall of the room; during the process, the cleaning robot several times Leaving the outer wall of the wall and moving away from the outer wall of the wall and cleaning the ground; each time the cleaning robot leaves the outer wall of the wall for a certain distance or encounters an obstacle, it first turns a preset angle, and then travels for a certain distance Preset the distance, and then return to the outer wall of the wall to realize the traversal and cleaning of the area to be cleaned, and realize the cleaning of reducing repeated travel routes, but there is no way for the cleaning robot to avoid obstacles

Embodiment 1

[0040] Embodiment 1, with reference to Figure 1-Figure 3b As shown, when the obstacle is on the left side of the cleaning robot 1, when the cleaning robot 1 is going to approach the obstacle 2 while the cleaning robot 1 is moving, when it enters the effective range detected by the obstacle avoidance unit, the central control unit will receive The distance detection signal, and then give the feedback command of the cleaning robot 1. At this time, the cleaning robot 1 will retreat a certain distance according to the program setting, and then start turning right to avoid obstacles, and then go straight. This process may be repeated many times Correction: After the cleaning robot 1 avoids the obstacle on the side, it moves forward in the oblique direction. When the second distance sensor 4 that moves to the right side detects the obstacle, it cannot turn left to correct the direction at this time, and it needs to continue in the oblique direction. Go straight, and after the third...

Embodiment 2

[0041] Embodiment 2, with reference to Figure 4 As shown, when the cleaning robot 1 enters some narrow passages or corners, when the cleaning robot 1 cannot turn around to get out of trouble, it can exit backwards. At this time, the distance sensors on both sides are used to correct the route until the cleaning robot 1 exits the narrow passage smoothly. passages or corners without always bumping into walls or furniture.

[0042] The following provides a comparison with a conventional cleaning robot in the case of cleaning the same space through the system and method of the present invention as follows:

Abstract

The invention relates to a clean robot obstacle avoidance system and method. The system comprises a cleaning robot, multiple obstacle avoidance units arranged around the cleaning robot and a center control unit electrically connected with the obstacle avoidance units; the obstacle avoidance units are used for detecting obstacle information around the cleaning robot and transmitting the detected information to the center control unit in real time, and the center control unit controls the cleaning robot to conduct real-time obstacle avoidance according to the received information and continues to operate according to a preset path after avoidance is finished. Accordingly, the walking path of the cleaning robot can be corrected, avoidance is conducted on obstacles, the situation of colliding with the obstacles is avoided, and then furniture or a cleaning robot body cannot be destroyed, and the service life of the cleaning robot can be prolonged.
