Wherein:

The mobile platform 100 may be configured to automatically move along a target direction on the operation surface. The operating surface may be a surface to be cleaned by the automatic cleaning device. In some embodiments, the automatic cleaning device may be a floor mopping robot, and the automatic cleaning device works on the floor, which is the operation surface; the automatic cleaning equipment can also be a window cleaning robot, and works on the outer surface of the glass of the building, wherein the glass is the operation surface; the automatic cleaning device may also be a pipe cleaning robot, and the automatic cleaning device works on the inner surface of the pipe, which is the operation surface. Purely for the sake of illustration, the following description of the application will be given by way of example of a mopping robot.

In some embodiments, mobile platform 100 may be an autonomous mobile platform or a non-autonomous mobile platform. The autonomous mobile platform means that the mobile platform 100 itself can automatically and adaptively make operational decisions according to unexpected environmental inputs; the autonomous mobile platform itself cannot adaptively make operational decisions based on unexpected environmental inputs, but may execute a given program or operate in accordance with certain logic. Accordingly, when the mobile platform 100 is an autonomous mobile platform, the target direction may be autonomously determined by the automatic cleaning apparatus; when the mobile platform 100 is an autonomous mobile platform, the target direction may be set by a system or manually. When the mobile platform 100 is an autonomous mobile platform, the mobile platform 100 includes a forward portion 111 and a rearward portion 110.

The perception system 120 includes a position determining device 121 located above the mobile platform 100, a buffer 122 located at the forward portion 111 of the mobile platform 100, cliff sensors 123 and ultrasonic sensors (not shown) located at the bottom of the mobile platform, infrared sensors (not shown), magnetometers (not shown), accelerometers (not shown), gyroscopes (not shown), odometers (not shown), and the like sensing devices, which provide various positional and motion state information of the machine to the control system 130.

In order to describe the behavior of the automatic cleaning device more clearly, the following directional definition is made: the robotic cleaning device may travel on the floor by various combinations of movements relative to three mutually perpendicular axes defined by the mobile platform 100: a transverse axis Y, a front-to-back axis X and a central vertical axis Z. The forward driving direction along the front-rear axis X is denoted as "forward", and the backward driving direction along the front-rear axis X is denoted as "backward". The transverse axis Y extends between the right and left wheels of the robotic cleaning device substantially along an axle defined by the center point of the drive wheel assembly 141. Wherein the automatic cleaning device is rotatable about the Y-axis. The rearward portion is "pitched up" when the forward portion of the automatic cleaning device is tilted up, and the rearward portion is "pitched down" when the forward portion of the automatic cleaning device is tilted down. In addition, the robotic cleaning device may rotate about the Z-axis. In the forward direction of the automatic cleaning apparatus, the right turn is when the automatic cleaning apparatus is tilted to the right of the X axis, and the left turn is when the automatic cleaning apparatus is tilted to the left of the X axis.

As shown in fig. 2, cliff sensors 123 for preventing falling when the robot cleaner is retreated are provided on the bottom of the moving platform 100 and in front and rear of the driving wheel assembly 141, so that the robot cleaner can be prevented from being damaged.

Further, the control system 130 may also determine whether to start the cleaning module 150 to perform the cleaning operation according to the environmental information and the environmental map.

Specifically, the control system 130 may combine the distance information and the speed information fed back by the buffer 122, the cliff sensor 123, the ultrasonic sensor, the infrared sensor, the magnetometer, the accelerometer, the gyroscope, the odometer and other sensing devices to comprehensively determine what working state the sweeper is currently in, such as passing a threshold, going up a carpet, being located at the cliff, being blocked above or below, being full of dust box, being lifted up, and the like, and may further give a specific next action strategy according to different situations, so that the work of the automatic cleaning device better meets the requirements of the owner, and has better user experience. Furthermore, the control system can plan the most efficient and reasonable cleaning path and cleaning mode based on the instant map information drawn by SLAM, and greatly improves the cleaning efficiency of the automatic cleaning equipment.

As shown in fig. 2, the cleaning module 150 may include a dry cleaning module 151.

The dry cleaning module 151 includes a rolling brush, a dust box, a fan, and an air outlet. The rolling brush with certain interference with the ground sweeps up the garbage on the ground and winds up the garbage in front of the dust collection opening between the rolling brush and the dust box, and then the dust box is sucked by the suction gas generated by the fan and passing through the dust box. The dust removal capability of the sweeper can be characterized by the sweeping efficiency DPU (Dust pickup efficiency) of the garbage, the sweeping efficiency DPU is influenced by the structure and the material of the rolling brush, the wind power utilization rate of an air duct formed by a dust collection port, a dust box, a fan, an air outlet and connecting parts among the four components is influenced, and the type and the power of the fan are influenced, so that the sweeper is a complex system design problem. The improvement in dust removal capability is of greater significance for energy-limited cleaning automatic cleaning equipment than for conventional plug-in cleaners. Because the dust removal capability is improved, the energy requirement is directly and effectively reduced, that is to say, the original machine which can clean the ground of 80 square meters after charging once can be evolved into the machine which can clean the ground of 180 square meters or more after charging once. And the service life of the battery with reduced charging times can be greatly prolonged, so that the frequency of replacing the battery by a user can be reduced. More intuitively and importantly, the improvement of dust removal capability is the most obvious and important user experience, and users can directly draw a conclusion on whether the dust is cleaned/rubbed clean. The dry cleaning module may also include a side brush 152 having a rotational axis that is angled relative to the floor for moving debris into the roller brush area of the cleaning module 150.
