Problems solved by technology

[0002] The robots in the prior art mainly rely on the single-point laser sensor configured at the front end to obtain the information of surrounding obstacles. However, due to the limitation of the installation height of the laser sensor, it is often difficult for the robot to quickly detect some low-level obstacles, thus lacking sufficient Environmental Awareness
[0003] In addition, the robots in the prior art also mainly rely on single-point infrared sensors arranged on the side when performing edge-along operations. In other words, the efficiency of this edge-alonging method is not high, and it is difficult to achieve the effect of effectively edge-alonging

Embodiment 1

[0052] figure 1 It is a schematic flowchart of the method for edge-adhering a robot provided in Embodiment 1 of the present application, and the method may include the following steps:

[0053] S101: When the robot is working, use a first line laser sensor to detect whether there is a first obstacle in the moving direction of the robot.

[0054] In one embodiment, the movements of the robot include, but are not limited to, forward, backward, turn left and turn right.

[0055] In one embodiment, if the first line laser sensor detects an echo signal within a preset time period, it is determined that there is a first obstacle in the movement direction; otherwise, it does not exist.

[0056] In one embodiment, after detecting whether there is a first obstacle in the moving direction of the robot through the first line laser sensor, an electronic map corresponding to the detection result may be created for subsequent use.

[0057] It should be noted that, when the first line lase...

Embodiment 2

[0077] figure 2 The schematic flowchart of the method for edge-adhering a robot provided in Embodiment 2 of the present application is a further refinement and description of steps S102 and S103 in Embodiment 1 above. The method may include the following steps:

[0078] S201: When the robot is working, use a first line laser sensor to detect whether there is a first obstacle in the moving direction of the robot.

[0079] The above step S201 is the same as the step S101 in the first embodiment, and the specific implementation process can refer to the description of the step S101, which will not be repeated here.

[0080] S202: When it is detected that there is a first obstacle in the moving direction of the robot, if the robot moves to a position where the distance from the first obstacle is a second preset value, perform deceleration and adjust the pose operation to determine whether the distance between the robot and the first obstacle is a first preset value.

Embodiment 3

[0095] image 3 It is a schematic structural diagram of the robot provided in the third embodiment of the present application. like image 3 As shown, the robot 3 of this embodiment includes a processor 30 , a memory 31 , and a computer program 32 stored in the memory 31 and executable on the processor 30 . When the processor 30 executes the computer program 32, the steps in the first embodiment of the above-mentioned method are implemented, for example, figure 1 Steps S101 to S103 are shown. Or, implement the steps in the second embodiment of the above method, for example figure 2 Steps S201 to S204 are shown.

[0096] The robot 3 may be an indoor cleaning robot, such as a sweeping robot, a mopping robot or an all-in-one sweeping and mopping machine. The robot may include, but is not limited to, a processor 30 and a memory 31 . Those skilled in the art can understand that, image 3 It is only an example of the robot 3, and does not constitute a limitation on the robot...

Abstract

This application uses the first line laser sensor to detect whether there is a first obstacle in the moving direction of the robot. The first line laser sensor is installed on the front end of the robot. Whether the distance between the obstacles is the first preset value, when the distance between the robot and the first obstacle is the first preset value, the information collected by the second line laser sensor is used to perform edge-to-edge operations on the first obstacle, the second The second-line laser sensor is installed on the side of the robot. On the one hand, the application can detect whether there are low obstacles in the moving direction of the robot through the first-line laser sensor installed on the front end, which is beneficial to improve the robot's perception of the surrounding environment; on the other hand, through the second laser sensor installed on the side The laser sensor can realize multi-point edge-along operation, which is beneficial to improve the edge-edge efficiency of the robot for irregular obstacles.

Description

technical field [0001] The present application relates to the technical field of household cleaning robots, and in particular, to a method and a robot for edge-following a robot. Background technique [0002] Robots in the prior art mainly rely on a single-point laser sensor configured at the front end to obtain information about surrounding obstacles. However, due to the limitation of the installation height of the laser sensor, it is often difficult for robots to quickly detect some low-level obstacles. environmental awareness. [0003] In addition, the robot in the prior art also mainly relies on the single-point infrared sensor configured on the side to perform the edgewise operation. However, since this edgewise method can only achieve the effect of a single-point edgewise operation, it is not suitable for irregular obstacles. In other words, this edge edge method is also inefficient, and it is difficult to achieve the effect of effective edge edge. [0004] Therefore...
