Problems solved by technology

[0004] In the above-mentioned first solution, the gears on the casters are easy to get dust, which is easy to break, and the production cost is too high, the mechanism is complicated and troublesome, and there are connecting wires in the wheels, which are easy to be turned and broken, and they also work in fixed-point rotation of the machine. mode, but it is impossible to judge whether the front is suspended
In the second solution, since the outer surface is easily polluted when the casters move on the ground, the light reflectance of coatings with different light reflectivity on the outer surface will tend to be the same in the long run, thus affecting the accurate judgment of the optical sensor

Embodiment Construction

[0034] The technical scheme of the present invention is described in detail below in conjunction with the embodiment shown in the accompanying drawings:

[0035] What this embodiment enumerates is a kind of self-moving floor cleaning robot, such as Figure 1~3 As shown, the self-moving floor cleaning robot has a robot body 1 capable of moving back and forth and rotating on the ground to be cleaned, and the robot body 1 has a shell made of a top wall 2, a bottom wall 3 and an outer peripheral side wall 4 body.

[0036] The robot body 1 is provided with a cleaning unit 7 for removing dirt on the ground to be cleaned during the movement of the robot body 1 . In this example, the cleaning unit is composed of a dust suction module, a mop cleaning module and a sponge cleaning module. Wherein, the dust collection module includes a dust collection motor 17 arranged inside the robot body 1, a dust suction port 5 provided on the bottom wall 3, a dust collection box 18 and a filter com...

Abstract

The invention relates to an autonomous mobile robot and its control method. The robot has a robot body capable of moving on the ground, including at least one driven wheel unit and a driven wheel rotation detection unit. The driven wheel at the bottom of the robot body, the driven wheel can be rotated by the movement of the robot body; the driven wheel rotation detection unit includes at least one magnetic element and a magnetic field sensing element, the magnetic element is arranged on the driven wheel and can generate a magnetic field around the driven wheel, The magnetic field sensing element is arranged near the driven wheel and is used to sense the change of the magnetic field generated by the magnetic element. The passive wheel of the present invention rotates, and the magnetic element rotates together with the passive wheel, causing the surrounding magnetic field to change regularly, and the magnetic field sensing element indirectly transmits the information of whether the robot body is in normal operation to the main control unit through the detection of the magnetic field transformation, thereby providing autonomous Mobile robots provide guarantees for smooth and continuous work.

Description

technical field [0001] The invention relates to an autonomous mobile robot and a control method thereof, in particular to an autonomous mobile robot and a control method thereof which can be known by a main control unit in time when a movement abnormality occurs during the self-movement process. Background technique [0002] Autonomous mobile robots are robots that can move on the ground by themselves. At present, autonomous mobile robots include self-moving ground cleaning robots, self-moving patrol robots, etc. Since autonomous mobile robots move on the ground by themselves, autonomous mobile robots need to have one or more active wheels or feet for active walking and one or more passive wheels. The wheel can be a universal wheel or a wheel with a fixed shaft, which can support the weight of the robot or passively detect the speed of travel. When the robot moves normally, the passive wheels continue to rotate; when the robot encounters obstacles and is blocked or the acti...
