The handle includes a hand grip, and a multi-connecting rod assembly. The hand grip is configured to be held by a user. The multi-connecting rod assembly connects the hand grip and the body. The multi-connecting rod assembly includes at least a first connecting rod, a second connecting rod, and a rotary device connecting the first connecting rod and the second connecting rod. The switch is configured to be operated to a lock position and an unlocked position.

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.

Provided is an electric work vehicle having a simple configuration, yet allowing a hydraulic cylinder to function appropriately even in a low-temperature environment. An electric work vehicle includes a first hydraulic cylinder, a second hydraulic cylinder and a third hydraulic cylinder and includes also a hydraulic system for feeding work oil to these hydraulic cylinders and a traveling motor. The hydraulic system includes an oil heating circuit for heating the work oil using heat generated from the traveling motor.

In an electric work vehicle, a power feeding assembly which connects a battery device to a power controller unit so as to feed power includes a fixed connector which is fixed to the battery device and electrically connected to the battery device, a cable harness connected to a power controller unit, and a free connector which is connected to an end of the cable harness and connectable to a fixed connector, and a connecting operation tool is configured to be movable the free connector between the connecting position in which the free connector is connected to the fixed connector and the detaching position.

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.

A mower can dynamically adjust the cutting height of a mower deck based on a mower's location. As a mower travels over an area of grass to be cut, a control system can track the current location of each mower deck on the mower. The control system can compare the current location of a mower deck to a boundary of one or more sections defined within the area to thereby determine which section the mower deck is within. When the control system detects that a mower deck has crossed or will cross into a section, it can identify a particular cutting height assigned to the section and dynamically adjust the cutting height of the mower deck to the particular cutting height. When a mower includes more than one mower deck, the control system can be configured to independently adjust the cutting height of each mower deck based on its location.

The present disclosure discloses a charging station, an intelligent robot, and a charging system. The charging station includes a control chip, a charging apparatus, and a differential positioning apparatus. The charging apparatus is electrically connected to the control chip, and the differential positioning apparatus is communicatively connected to the control chip, where the control chip is configured to receive first observation information and position information of the charging station sent by the differential positioning apparatus, and send the first observation information and the position information to an intelligent robot, and configured to control the charging apparatus to charge the intelligent robot.

The present invention relates to a mobile robot system for autonomously traveling in a travel area, and a method for generating boundary information of the mobile robot system, the mobile robot system being characterized by comprising: a transmitter for transmitting a transmission signal including location information; and a mobile robot which moves and rotates on the basis of the separation distance to the transmitter and the angle with respect to the transmitter, and generates boundary information on a travel area by using a movement path, wherein the transmitter moves along the periphery of the mobile robot and changes the separation distance and the angle to control the travel of the mobile robot.
