This invention relates to an information management system of lawn profile data. It comprises a lawn profile information collecting tool for collecting information any pieces of lawns that need mowing jobs; wherein the lawn profile information collecting tool includes a data converter for converting such information to lawn profile data, and data processer for processing the lawn profile data locally into suitable formats and categories for uploading; a mobile device of a user being in communication with the lawn profile information collecting tool to receive the processed lawn profile data; a remote information processing center being in communication with the mobile device and the lawn profile information collecting tool to receive and process requests from the mobile device to upload the lawn profile data; wherein the remote information processing center includes a data storage unit for storing the lawn profile data for usage thereof by a designated lawn mower to perform mowing job, that is, using the stored lawn profile data associated with the particular piece of lawn as requested.

A work vehicle includes a cutter device for cutting plant in a field, a storage section for storing plant cut by the cutter device, an inclination angle sensor for detecting an inclination angle ((θd)) of the vehicle body, a display device for displaying the inclination angle detected by the inclination angle sensor, and a reporting device for reporting the inclination angle exceeding a permissible inclination angle ((θa)).

An integrated navigation method for a mobile vehicle is provided, which includes: acquiring a motion measurement of the mobile vehicle by using an inertial navigation element in the mobile vehicle and calculating a gesture parameter of the mobile vehicle based on the motion parameter; estimating, based on the gesture parameter, a motion state of the mobile vehicle in a real time manner by using a satellite navigation element in the mobile vehicle to obtain an error estimation value of the motion state, and correcting a motion parameter of the mobile vehicle based on the error estimation value of the motion state; and controlling an operation route of the mobile vehicle based on corrected navigation information.

A system and method for differential traction drive and steering axis coordination for an autonomous mower or other turf device includes initiating a steering motion based on determining a target forward speed and a steering rotational speed, calculating a left wheel speed and a right wheel speed, and applying the left and right wheel speeds, wherein the steering rotational speed is driven by a steering motor and the traction wheels associated with the autonomous mower, and the left and right wheel speeds are based on the target forward speed, a distance from a steering axle to the center of the respective wheel, and the steering rotational speed.

An outdoor power equipment with steering and/or speed controlled via foot-based inputs is discussed. One example embodiment is an outdoor power equipment, comprising: a frame; a plurality of drive elements coupled to the frame; a prime mover configured to provide power to the plurality of drive elements; one or more controls configured to receive foot-based inputs from an operator of the outdoor power equipment; and a control system configured to control a steering and a speed of the outdoor power equipment based on the foot-based inputs. Various foot-based embodiments and control systems can be employed based on the embodiment.

A mobile robot and a method of controlling the same are provided, and more specifically, a technology of automatically generating a map of a lawn working area by a lawn mower robot. The mobile robot includes one or more tags configured to receive a signal from one or more beacons, a vision sensor configured to distinguish and recognize a first area and a second area on a travelling path of the mobile robot and acquire position information of a boundary line between the first area and the second area, and at least one processor configured to determine position coordinates of the mobile robot based on pre-stored position information of the one or more beacons, determine position coordinates of the boundary line based on the determined position coordinates of the mobile robot and the acquired position information of the boundary line, and generate a map of the first area while travelling along the determined position coordinates of the boundary line.

There are included front and back slope portions attachable to and detachable from storage positions and use positions, front and back holding portions capable of engaging with engagement portions of the front and back slope portions as attached to the storage positions and holding the front and back slope portions at the storage positions, and a disengaging operation tool capable of being manually operated to a disengaging position at which the front holding portion and the back holding portion are releasable from the engagement portions of the front and back slope portions and at which the slope portions are detachable from the storage positions.

Certain exemplary embodiments can provide a system comprising a zero turn riding lawnmower. The zero turn riding lawnmower is steerable solely via a first foot pedal and a second foot pedal. Each of the first foot pedal and the second foot pedal coupled to a mower linkage of the zero turn riding lawnmower. The first foot pedal is constructed to cause at least one wheel on a first side the zero turn riding lawnmower to be powered in a forward direction or a reverse direction. The second foot pedal is constructed to cause at least one wheel on a second side the zero turn riding lawnmower to be powered in a forward or reverse direction.

The present specification relates to a mobile robot system and a boundary information generation method for the mobile robot system, the mobile robot system comprising a signal processing device that comprises a receiving tag for receiving a transmission signal and a distance sensor, so as to recognize coordinate information about a spot at which the point of the distance sensor is designated on the basis of the reception result of the receiving tag and the distance measurement result of the distance sensor, thereby generating boundary information according to the path designated as the point of the distance sensor on the basis of the recognized coordinate information.
