Problems solved by technology

The current cleaning robot is generally equipped with multiple sets of sensors at the bottom of the robot body. The function of the sensor is to prevent the cleaning robot from falling from the cliff table, causing damage to the machine and even damage to the user.
[0004] In order to locate the orientation of the cliff, the bottom of the existing robot body is provided with multiple sets of sensors, which can detect the orientation of the cliff in multiple directions. interfere with each other
like figure 1 As shown, the signal transmitting end 11 and the signal receiving end 12 are a set of downward-looking sensors, and the signal transmitting end 11' and the signal receiving end 12' are a set of downward-looking sensors. If the signal transmitting end 11 and the signal transmitting end 11' transmit simultaneously signal, the intersection area 13 and the intersection area 13' are the areas where the signal receiving end 11 can receive the signal. If the signal receiving end 11 receives the signal at this time, it will receive the signals of the intersection area 13 and the intersection area 13', and the signal reception strength increases. Large, resulting in the inability to accurately detect the cliff, which is likely to cause the robot to fall off the cliff

Embodiment 1

[0042] An embodiment of the present invention provides a method for controlling the travel of an autonomous robot row. The autonomous robot may be, for example, a cleaning robot, which is not limited in this embodiment.

[0043] The bottom of the autonomous robot in this embodiment is provided with at least two groups of downward-looking sensors, and each group of downward-looking sensors includes a signal transmitting end and a signal receiving end. Down-looking sensors are used to detect cliffs. Specifically, since the autonomous robot can drive the moving parts such as wheels to advance automatically under the control of its internal controller, it is easy to encounter a cliff with a large height difference from the working surface. Therefore, at least Two sets of downward-looking sensors to detect the position of the cliff. The downward looking sensor here may be, for example, an infrared sensor, which is not limited in this embodiment.

[0044] Usually, multiple sets of...

Embodiment 2

[0093] An embodiment of the present invention provides an autonomous robot, which includes at least two sets of downward-looking sensors and a controller. At least two groups of downward-looking sensors are arranged on the bottom of the autonomous robot, each group of downward-looking sensors includes a signal transmitting end and a signal receiving end, and the downward-looking sensors are used for detecting cliffs.

[0094] In the autonomous robot of this embodiment, since the controller can use the method in Embodiment 1 to control the autonomous robot, it can prevent the signal receiving end of the downward-looking sensor from being interfered by other downward-looking sensors when receiving signals, and the cliff detection is accurate.

[0095] Refer below Figure 10 , which shows a schematic structural diagram of a controller suitable for implementing the embodiments of the present application. Figure 10 The illustrated controller is only an example, and should not imp...

Abstract

The invention discloses a travel control method of an autonomous robot, the autonomous robot and a storage medium. At least two groups of downward-looking sensors are arranged at the bottom of the autonomous robot, each group of downward-looking sensors comprises a signal transmitting end and a signal receiving end which correspond to each other, and the downward-looking sensors are used for detecting cliff. The method comprises the following steps: alternately selecting the signal transmitting ends to transmit signals; and controlling the autonomous robot to avoid the cliff according to the signal detected by the corresponding signal receiving end. According to the invention, the accuracy of cliff detection can be improved while the orientation of the cliff is accurately positioned.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a traveling control method of an autonomous robot, an autonomous robot and a storage medium. Background technique [0002] An autonomous robot is a robot that has various sensors and controllers on its body, and can independently complete predetermined tasks under the condition of no external human information input and control during its operation. For example cleaning robots. [0003] At present, cleaning robots have been widely used in daily family life, and cliff sensors, as an important part of sweeping machines, are indispensable. The current cleaning robot is generally provided with multiple sets of sensors at the bottom of the robot body. The function of the sensors is to prevent the cleaning robot from falling from the cliff table, causing damage to the machine and even to the user. [0004] In order to locate the orientation of the cliff, the bottom of the ...
