The present disclosure relates to an automatic lawn mower, comprising: a moving assembly for driving the automatic lawn mower to move within a working area; a cutting assembly for performing cutting tasks to form a cutting area; and a controller for controlling the automatic lawn mower to operate within the working area, wherein the working area comprises a first area and a second area, the first area being adjacent to the second area, and the boundary between the two areas being a common boundary; the cutting assembly is controlled to perform cutting on the first area at a first cutting height and on the second area at a second cutting height, the first cutting height being less than the second cutting height; when the cutting assembly performs cutting tasks at the first cutting height, the moving assembly is controlled to move along the common boundary, while ensuring that at least part of the cutting area is within the first area. The present disclosure not only avoids missing a spot during cutting along the common boundary, but also prevents the cutting area from excessively extending to the second area, so as to prevent an excessive amount of grass height in the second area from being cut off at once, thereby reducing the risk of the lawn turning yellow due to excessive exposure and water loss.

This invention relates to an obstacle detection method and an automatic lawnmower based on radar and vision fusion. The obstacle detection method first initializes by synchronizing the time and aligning the space of radar and vision methods. Then, it acquires obstacle position information using radar and vision methods respectively. Finally, it fuses the two obstacle position information to obtain the final obstacle information, thereby effectively avoiding the problem that existing lawnmowers cannot avoid obstacles well when vision acquisition is poor.

A control device for an autonomous lawn mower is described which receives input signals from a first and / or second hand control and determines a control signal for controlling the autonomous lawn mower. The hand controls may provide for intuitive control of the mower by a user. The control signals may be used to operate the autonomous lawn mower to perform a task such that, when later detached or otherwise decoupled, the autonomous lawn mower may perform the same or similar tasks substantially autonomously based on data (e.g., sensor signals, control signals, etc.), generated during manual operation. In some examples, the control signals may be determined to aid a user in maintaining a straight mow, proximity to a desired pattern for mowing, and / or be otherwise altered based on the presence of a user.
