Abstract: A mower includes a mower main body and a controller. The mower main body includes a mowing blade for mowing grass. The controller identifies subsidence on a ground surface where the mower main body is not able to travel based on three-dimensional point cloud data composed of three-dimensional data of multiple positioning points in a target area, and sets a travel route of the mower main body by avoiding the identified subsidence.

Abstract: The mower includes a mower body having a mower blade portion for mowing grass, a first position estimation unit for estimating a self position of the mower main body using a satellite positioning system, a second position estimation unit for estimating a self position of the mower body using a sensor portion provided in the mower body, a detection unit for detecting a portion covered with grass and tree on a preset travel path, and an automatic travel control unit for causing the mower body to travel on the travel path with reference to the self position estimated by the first position estimation unit, and for causing the mower body to travel by switching to refer to the self position estimated by the second position estimation unit at a portion covered with the grass and tree detected by the detection unit.

Abstract: A mower includes: driving devices respectively provided on a right side and a left side of the mower and configured to be driven independently; and one or more processors configured to: estimate a gradient of a slope on a travel path; and drive the driving devices with different driving forces on the right side and the left side based on the estimated gradient such that the mower does not slip down the slope when the mower travels in a direction crossing the slope.
