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.

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 Z1 and Z2 in 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 Z1 and Z2, a current position used for autonomous traveling is corrected to the current position detected by the second position detecting unit.

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.

A station for a lawn mower for charging a storage battery included in the lawn mower that autonomously travels and perform specified work, the station including: a base that stores the lawn mower; and a power supply device that supplies electric power to the storage battery included in the lawn mower when the lawn mower is stored in the base, in which the power supply device or the base includes power supply means for supplying electric power from the power supply device to power receiving means for supplying received electric power to the storage battery included in the lawn mower, and the power supply device is attachable to and detachable from the base.

Vision systems for autonomous machines and methods of using same during machine localization are provided. Exemplary systems and methods may reduce computing resources needed to perform vision-based localization by selecting the most appropriate camera from two or more cameras, and optionally selecting only a portion of the selected camera's field of view, from which to perform vision-based location correction. Other embodiments may provide camera lens coverings that maintain optical clarity while operating within debris-filled environments.

A lawnmower cutter assembly (22) comprises a knife carrier arrangement (26) and a skid plate arrangement (30), which are axially held between an axial stop shoulder (60) of the cutter drive shaft (34) and an end piece (54) rigidly connected to the cutter drive shaft (34), the end piece (54) thereby vertically carrying the skid plate arrangement (30) and the knife carrier arrangement (26). The cutter assembly (22) may be attached to a lawnmower, which may be a robotic lawnmower, by positioning the knife carrier arrangement (26) and the skid plate arrangement (30) on the cutter drive shaft (34); and thereafter, axially locking the axial position of the knife carrier arrangement (26) and the skid plate arrangement (30) in relation to the cutter drive shaft (34).

An automatic working system comprises a self-moving device moving and working in a working region, a handheld device and a control module. The handheld device is configured to move along a perimeter of the working region with a user and comprises a detecting module, detecting the perimeter information of the working region; and an input module, receiving a command of the user for detecting the perimeter information. The control module comprises a perimeter setting unit, generating virtual data of the perimeter, an area calculation unit calculating the area of the working region and a scheduling unit generating a working schedule. The self-moving device comprises a working module, a driving module and a controller. The controller controls the self-moving device to work according to the working schedule.

A moving robot has a body and at least one wheel for moving the main body. The moving robot has a transceiver to communicate with a plurality of location information transmitters located within an area. The moving robot also has a memory storing coordinate information regarding positions of the location information transmitters. Further, the moving robot has a controller that sets a virtual boundary based on location information determined using signals transmitted by the location information transmitters. The controller controls the wheel so that the main body is prevented from traveling outside the virtual boundary. The controller sets a reference location information transmitter and corrects the stored coordinate information by correcting height errors based on height differences between the reference location information transmitter and the other location information transmitters. The controller also corrects a current position of the main body based on the corrected stored coordinate information.

A robotic work tool system, comprising a charging station and a robotic work tool, said robotic work tool comprising two charging connectors arranged on an upper side of the robotic work tool and said charging station comprising two charging connectors and a supporting structure arranged to carry said charging connectors and to extend over and above said robotic work tool as the robotic work tool enters the charging station for establishing electrical contact between the charging connectors of the robotic work tool and the charging connectors of the charging station from above, wherein said supporting structure is arranged to allow the robotic work tool exit the charging station by driving through the charging station without reversing.

A lawn mowing apparatus may include sensors that are fastened to both its mower deck and its chassis. The sensors may sense a position of the mower deck in relation to the chassis. The sensed position of the mower deck may be presented to the operator via a dashboard display of the lawn tractor or transmitted via a wireless signal to another device. Based on such sensed position, an operator of the lawn tractor may manually adjust the position of the mower deck until the sensed position of the mower deck is within an acceptable operating range. In some embodiments, servomotors may used to adjust the position of the mower deck until the sensed position of the mower deck is within an acceptable range.
