摘要： Disclosed are solutions for proactively sensing the condition of the ground in the path of the autonomous vehicle in order to mitigate the risks of an autonomous vehicle encountering troublesome terrain, navigation obstacles, and other potential risks to the continued uninterrupted operation of said autonomous vehicle. Accordingly, various implementations disclosed herein are directed to the use of ground analysis sensors to assist in the detection of navigationally difficult terrain including, for example, the use of cantilevered sensors operating well in front of the autonomous vehicle's front wheels (drive wheels or otherwise).

摘要： A flexible rotary mower deck lift system includes a center deck having a first end and a second end, and a wing deck pivotably attached to each of the first and second ends. A linear actuator may be actuated to raise and hold each wing deck at a position that is parallel to the center deck, and a lift cylinder may be actuated to raise the center deck and the wing decks together to an intermediate position above a ground surface wherein the center deck and the wing decks are out of contact with the ground surface.

摘要： A system for use with an autonomous working machine such as a robotic lawn mower. The system may allow communication (directly or indirectly) between the machine and a gate or other barrier opening to allow unattended or remotely-controlled passage of the machine through the gate. In some embodiments, the mower may include a vision system operable to detect unknown objects within an area adjacent to the gate.

摘要： A robotic lawn mower comprises a frame, a first wheel set, and a second wheel set, wherein the first wheel set and the second wheel set are respectively arranged at opposite rear and front ends of the frame, the first wheel set is equipped with driving wheels, and the second wheel set is equipped with omni-directional wheels. The robotic lawn mower further comprises a controller, a first driving module, and a second driving module, wherein the controller is connected to each of the driving modules, the controller controls the first driving module to drive the first wheel set to move so as to provide main power to the robotic lawn mower, and the controller further controls the second driving module to drive the second wheel set to rotate so as to provide auxiliary power for overcoming a resistance generated by the ground when the second wheel set rotates.

摘要： A handle adjustment assembly is attached to a walk-behind lawn mower, wherein the handle adjustment assembly is rotatably adjustable relative to a deck of the mower to allow the handle to be adjusted to multiple different heights relative to the ground at distinct operative positions. The handle adjustment assembly is also rotatable to allow the handle to be adjusted to a stored position adjacent to the deck, wherein the mower can be stored in a substantially vertical orientation.

摘要： A lawn mower includes: a cutting blade motor that drives a cutting blade; a mode selector that selects one of modes including a normal lawn mowing mode and a grass removal mode in which grass accumulated at the cutting blade is brushed away; and processing circuitry configured to control the cutting blade motor in the mode selected by the mode selector. In the normal lawn mowing mode, the cutting blade motor is controlled so as to rotate in a normal rotation direction at a predetermined rotational frequency or with a predetermined torque. In the grass removal mode, the cutting blade motor is controlled such that the rotational frequency or torque of the cutting blade motor changes more significantly than the rotational frequency or torque of the cutting blade motor in the normal lawn mowing mode, or the cutting blade motor rotates in a reverse rotation direction.

摘要： A utility vehicle includes a frame, a first ground-engaging element coupled to a first portion of the frame, a second ground-engaging element coupled to a second portion of the frame, an operator platform supported by the frame, and a suspension system coupled between the operator platform and the frame to accommodate motion of the frame relative to the operator platform. The suspension system includes a first linkage assembly coupled to the operator platform and operable to accommodate motion of the second portion of the frame relative to the operator platform and a second linkage assembly having a first end coupled to the frame to secure the suspension system to the frame and a second end coupled to the first linkage assembly. The second linkage assembly being operable independent of the first linkage assembly to accommodate motion of the first portion of the frame relative to the operator platform.
