The present invention provides a robot gardening tool system and a method for a robot gardening tool. The robot gardening tool system comprises a robot gardening tool and a boundary module. The boundary module delimits a work area and/or a non-work area of the robot gardening tool, and the boundary module comprises at least one boundary element. The robot gardening tool comprises a boundary detection apparatus, a jamming detection apparatus and a control apparatus. The boundary detection apparatus detects the at least one boundary element; the jamming detection apparatus judges whether the robot gardening tool is jammed based on a feedback signal S.sub.i of the boundary detection apparatus; and the control apparatus controls the robot gardening tool to perform an extrication operation when the robot gardening tool is jammed. The present invention also provides a method for a robot gardening tool. The robot gardening tool system and method for a robot gardening tool according to the present invention enable effective detection of jamming, reduce misjudgements, and can perform effective operations on work areas where jamming is likely.

A mower cutting unit lift system includes a rotary motor connected to a power supply and turning an output shaft connected to a bell crank. A flexible link between the bell crank and a lift arm is used to lift a cutting unit to a transport position if the rotary motor turns the output shaft and the bell crank in a first direction, and lower the cutting unit to a mowing position if the rotary motor turns the output shaft and the bell crank in a second direction.

Provided is an accommodation device capable of transporting a work vehicle(s) smoothly. The accommodation device is configured to accommodate a plurality of work vehicles that carry out a work while traveling autonomously, including a plurality of accommodation cases mounted on a load carrying bed of a transporter vehicle being capable of accommodating the plurality of work vehicles individually, a supporting section for supporting the plurality of accommodation cases respectively with allowing movement thereof along a preset path, an actuator for driving the supporting section for causing the accommodation cases to move along the path, and an electric generator for supplying electric power to the actuator.

A method navigates a robotic mower by means of a wire. The robotic mower comprises at least one sensor. The method comprises detecting, by means of the at least one sensor, at least one signal from the wire, controlling the robotic mower to align with the wire, controlling the robotic mower to turn by an angle with respect to a section of the wire, controlling the robotic mower to increase the distance between the robotic mower and the wire by driving a displacement distance based on a random distance value, measuring, by means of the at least one sensor, a signal level of the at least one signal from the wire, and controlling the robotic mower to follow the wire based on the measured signal level.

Systems, methods and apparatus for the thermal conversion of biomass into biochar. A mobile platform may be used to maneuver a mobile biochar generation system within a field of biomass. The biomass may be harvested, preprocessed and pyrolyzed. After pyrolyzation, the biochar may be cooled to a predetermined temperature by integrating water and liquid nutrients into the biochar. The system may then control the application of the infused biochar by adjusting a spreading attachment and a plowing attachment.

A carburetor includes a carburetor bowl, a fuel supply pipe, a fuel drain pipe, and a valve. The carburetor bowl is configured to store fuel and provide the fuel to an air passage. The fuel supply pipe is connected a fuel tank and the carburetor bowl. The fuel drain pipe is connected to the carburetor bowl and the fuel supply line. The valve for the fuel drain pipe is configured to open and close in response to an orientation of the carburetor.

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.

An interchangeable and dual-functional robot is disclosed. The robot includes a portable electronic box to couple or uncouple with the lawn mower body. When the portable electronic box is in the recess of the lawn mower body, the portable electronic box connects to the mechanical and electronic components of the lawn mower body such that the coupled system functions as a robotic lawn mower. When the portable electronic box is taken out of the lawn mower body, the portable electronic box couples with a surveillance camera module to function as a mobile surveillance system. The portable electronic box may couple with a mobile cart or individual wheels to function as a mobile surveillance system.

In some embodiments, apparatuses, systems, and methods are provided herein useful to mowers. In some embodiments, a mower comprises a frame, a plurality of wheels connected to the frame, a mower deck located within the frame defining a cutting chamber, a first blade that is elongated and rotates about a generally vertical axis and has a fin extending from at least one of the ends with a concave surface that faces generally away from the ground surface, a second blade that is circular and rotates about a generally vertical axis, a propulsion unit that is supported by the frame and rotates the blades, a discharge opening allowing discharge to exit the cutting chamber, and a container pivotally coupled to the mower pivotable between a first position and a second position, with the first position of the container configured to collect the discharge from the cutting chamber through the discharge opening.

A lawn mower or stand-on powered drivable machine has an electrical port that receives current from an alternator powered by the engine or motor. The port receives a plug from a garment worn by the lawn mower operator. The garment includes one or more thermo-electric elements that are powered from current extending through the port. The thermo-electric (TEC) elements may be resistive heaters to warm the operator or TEC coolers to cool the operator. Furthermore, the garment may include a rechargeable battery that powers the thermo-electric elements when the plug is disconnected from the port.
