An autonomous work vehicle including a position information obtaining unit, a driving unit, a control unit, and a memory storing a destination position. The position information obtaining unit includes a GNSS receiver acquiring a position of the autonomous work vehicle. The driving unit includes a motor. The control unit includes a processor. The processor is configured to calculate a direction of the destination position relative to a current position of the autonomous work vehicle, wherein the direction is calculated using the current position of the autonomous work vehicle and the position of the predetermined destination, and the driving unit drives the autonomous work vehicle in a traveling direction toward the direction of the destination position calculated by the processor.

Travel route control of autonomous work vehicle to reduce travel distance

A map is stored in a robot that has a travelling unit, wherein the map is represented by a grid having a plurality of parcels, and a data set is assigned to each parcel such that the grid is represented by a plurality of data sets, each data set assigned to each parcel includes a characteristic value representing a characteristic of the parcel, and a grid value representing a shape of the parcel.

Map data having unequal interval

A growing state of a plant is appropriately managed with a convenient method. For example, a control apparatus to control a work machine with an autonomous movement function includes an illuminance information obtaining section to obtain the illuminance information indicating at least one of (i) the illuminance of the work machine in motion and (ii) the illuminance of a region located on an advancing direction of the work machine in motion and a control section to control at least one of an advancing direction, an advancing speed, a work mode and a travel mode of the work machine based on the illuminance information obtained by the illuminance information obtaining section.

Control apparatus, work machine, control method, and computer readable storage medium

An autonomous work vehicle including a positioning information obtaining unit including a GNSS receiver acquiring a position of the autonomous work vehicle, a driving unit including a motor, a memory storing position coordinates used to establish an entry avoidance zone, and a control unit including a processor. The control unit is configured to function as a zone entry judgement unit determining whether the autonomous work vehicle has approached the entry avoidance zone, and a zone entry validation unit determining whether the determination by the zone entry judgement unit that the autonomous work vehicle has approached the entry avoidance zone is valid. When the zone entry judgement unit determines that the autonomous work vehicle has approached the entry avoidance zone, and the zone entry validation unit determines that the determination by the zone entry judgement unit is valid, the control unit controls the autonomous work vehicle to perform an avoidance maneuver.

An autonomous work machine that works in a work area while autonomously traveling in the work area, comprises a specification unit configured to specify, based on information of a position detection unit configured to detect position information, a self-position of the autonomous work machine, a determination unit configured to determine, based on the self-position, whether the autonomous work machine has reached a perimeter portion of a no-work area positioned within the work area, and a control unit configured to control the autonomous work machine to do a lap along the perimeter portion in a case in which the autonomous work machine is determined to have reached the perimeter portion.

Autonomous work machine, method of controlling the same, and storage medium

A moving efficiency of a work machine decreases if an obstacle, an entrance prohibiting region, and the like are arranged inside a region, if a positioning precision of the work machine is relatively low, and the like. A control apparatus includes a control section to control a movement of a moving object based on at least one of a completion level of map information indicating a region where a moving object is permitted to enter and a location estimation precision of a moving object.

To make it possible to correct a current position detected by an autonomous traveling work machine to the correct position with a simple configuration. A robot lawn mower includes a first position detecting unit for detecting a current position by using odometry and a second position detecting unit for detecting a current position by using an image capture. When position detection accuracy of both of the first and second position detecting units decreases to less than or equal to a predetermined value, the robot lawn mower is controlled to travel to either of zones Zand Zin which the position detection accuracy of the second position detecting unit is relatively high, and when the robot lawn mower moves to either of the zones Zand Z, a current position used for autonomous traveling is corrected to the current position detected by the second position detecting unit.
