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 robotic cleaning device may be a floor-mopping robot, and the robotic cleaning device operates on a floor surface, the floor surface being the operating surface; the automatic cleaning equipment can also be a window cleaning robot, and the automatic cleaning equipment works on the outer surface of the glass of the building, wherein the glass is the operation surface; the automatic cleaning device can also be a pipeline cleaning robot, and the automatic cleaning device works on the inner surface of the pipeline, wherein the inner surface of the pipeline is the operation surface. The following description in this application is given by way of example of a floor-mopping robot, purely for illustration purposes.

In some embodiments, the 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 operation decisions according to unexpected environmental inputs; the non-autonomous mobile platform itself cannot adaptively make operational decisions based on unexpected environmental inputs, but may execute established programs or operate according to certain logic. Accordingly, when the mobile platform 100 is an autonomous mobile platform, the target direction may be autonomously determined by the robotic cleaning device; when the mobile platform 100 is a non-autonomous mobile platform, the target direction may be systematically or manually set. 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 sensing 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, a cliff sensor 123 and an ultrasonic sensor (not shown), an infrared sensor (not shown), a magnetometer (not shown), an accelerometer (not shown), a gyroscope (not shown), an odometer (not shown), and other sensing devices located at the bottom of the mobile platform, and provides various position information and motion state information of the machine to the control system 130.

To describe the behavior of the automatic cleaning device more clearly, the following directional definitions are made: the robotic cleaning device can travel over the floor through various combinations of movement relative to the following 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 forward-rearward axis X is denoted as "forward", and the rearward driving direction along the forward-rearward axis X is denoted as "rearward". The transverse axis Y extends substantially along the axis defined by the center points of the drive wheel assemblies 141 between the right and left wheels of the robotic cleaning device. Wherein the robotic cleaning device is rotatable about a Y-axis. The "pitch up" is when the forward portion of the automatic cleaning apparatus is tilted upward and the rearward portion is tilted downward, and the "pitch down" is when the forward portion of the automatic cleaning apparatus is tilted downward and the rearward portion is tilted upward. Additionally, the robotic cleaning device may be rotatable about the Z-axis. In the forward direction of the automatic cleaning apparatus, when the automatic cleaning apparatus is tilted to the right side of the X-axis, "right turn", when the automatic cleaning apparatus is tilted to the left side of the X-axis, "left turn".

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

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

Specifically, the control system 130 may comprehensively determine what working state the sweeper is currently in by combining 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, for example, when the distance information and the speed information are passed through a threshold, the sweeper is located at the cliff, the upper carpet or the lower carpet is stuck, the dust box is full, the sweeper is taken up and the like, and further, a specific next-step action strategy is given according to different conditions, so that the work of the automatic cleaning device better meets the requirements of an owner, and better user experience is achieved. Furthermore, the control system can plan the most efficient and reasonable cleaning path and cleaning mode based on the instant map information drawn by the SLAM, and the cleaning efficiency of the automatic cleaning equipment is greatly improved.

Compared with the common plug-in dust collector, the improvement of the dust removal capability is more significant for cleaning automatic cleaning equipment with limited energy. Because the improvement of the dust removal capability directly and effectively reduces the energy requirement, namely the machine which can clean the ground of 80 square meters by charging once can be developed into the machine which can clean 180 square meters or more by charging once. And the service life of the battery with reduced charging times is greatly increased, so that the frequency of replacing the battery by a user is reduced. More intuitively and importantly, the improvement of the dust removal capability is the most obvious and important user experience, and the user can directly draw a conclusion whether the sweeping/wiping is clean.
