  • Publication number: 20210064045
    Abstract: An autonomous snow removing machine includes: traveling apparatuses; a snow removal work unit; a region setting unit that sets a snow removal work region in which snow removal is performed by the snow removal work unit; and a control unit that controls the traveling apparatuses such that the traveling apparatuses do not deviate from the snow removal work region set by the region setting unit. As a result, the snow removal work can be performed while causing the autonomous snow removing machine to autonomously travel by controlling the traveling apparatuses in the snow removal work region set by the region setting unit.

  • Publication number: 20210061109
    Abstract: The invention includes a memory unit that stores electrical characteristics of a power receiving coil of an electric lawnmower and a power transfer coil of an external charger, wherein a battery side control circuit performs a test power transfer from a power transferring/receiving coil to the power receiving coil or the power transfer coil to obtain electrical characteristics of a power receiving side, compares the electrical characteristics to the electrical characteristics stored in the memory unit to determine whether the electrical characteristics are of a power transfer to the power receiving coil or of a power transfer to the power transfer coil, and performs control to switch to a power transfer mode with respect to the power receiving coil or to a power receiving mode with respect to the power transfer coil.

  • Publication number: 20210008602
    Abstract: A mower executes a mowing work while traveling autonomously. Furthermore, the mower includes a mower main body and a first controller that controls an operation of the mower main body so that the mower main body is washed with tap water that is supplied from a washing station. The mower includes, for example, a work unit that executes the mowing work, and the first controller operates the work unit so that the mower main body is washed.

  • Publication number: 20210008603
    Abstract: A cleaning system includes a mower that executes a mowing work while traveling autonomously, and a cleaning station that cleans the mower. The cleaning system includes: an acquirer that acquires dirt information relating to a state of dirt of the mower; a determiner that determines at least one of a necessity of cleaning the mower and a method of cleaning the mower, based on the dirt information; and a first cleaning executor that executes a cleaning operation, according to a determination result of the determiner.
