In a marker detection method in which a sensor unit (11) that includes a plurality of magnetic sensors arranged in a vehicle width direction is used to detect magnetic markers (10) laid in a road, a feature value that represent symmetry of magnetic distribution, which is the distribution of magnetic measurement values obtained by each magnetic sensor included in the sensor unit (11) is generated, and threshold process regarding the feature value is executed to determine the possibility of the presence of magnetic generation source other than magnetic marker (10), that causes disturbance, and hence to suppress erroneous detection.

An industrial vehicle comprising a tag reader, a reader module, and a diagnostic tag, wherein the diagnostic tag is coupled to the industrial truck within a read range of the tag reader. The reader module and the tag reader cooperate to identify the diagnostic tag and individual tags of a tag layout and the reader module discriminates between the individual tags of the tag layout and the diagnostic tag and the individual tags of the tag layout, correlates an identified individual tag of the tag layout with tag data, correlates an identified diagnostic tag with operation of the tag reader, and generates a missing tag signal if the diagnostic tag is not identified or the operation of the tag reader is not within specified operating parameters.

In an operation system (1) for a bus (5) including a connection point database which stores identification information of a magnetic marker (10) positioned so as to correspond to a connection point (13) between a dedicated lane (111) having magnetic markers (10) laid thereon and a general lane (112), the connection point (13) is set so as to correspond to the magnetic marker (10) according to identification information stored in a connection point database, thereby allowing flexibility in changing a route to be improved in the operation system which causes a vehicle to operate along a route defined in advance.

A movable platform for taking inventory and/or performing other actions on objects, the movable platform comprising a traction system for allowing the movable platform to circulate through an area, a sensor system for identifying objects in an area based on a characteristic, and for creating information indicative of the identified objects and the position of the identified objects relative to the movable platform and in absolute space coordinates, and a control system, wherein the control system is adapted to receive the information created by the sensor system and to determine a direction of movement or a partial path or a movement target for the movable platform based on the received information and without using a previously created map of the area.

In an installation method for laying magnetic markers (10) in a road for driving assist control on a vehicle side, a laying work vehicle (2) sequentially lays the magnetic markers (10) while moving along the road without performing a prior survey or the like of laying positions, and then by using a positioning work vehicle (3) including a magnetic sensor capable of detecting magnetism, the laid magnetic markers (10) are detected and the laying positions are identified to generate position data regarding the magnetic markers (10), thereby allowing reduction of cost of laying the magnetic markers (10).

An autonomous mobile robot includes a drive system to maneuver the autonomous mobile robot about an environment, a first magnetic field antenna system responsive to a magnetic field pulse to generate a first signal, and a second magnetic field antenna system responsive to the magnetic field pulse to generate a second signal. The magnetic field pulse is emitted by a magnetic field emitter system in the environment. The autonomous mobile robot further includes a controller to execute instructions to perform operations including reorienting the autonomous mobile robot based on the first signal and the second signal.

In a marker system (1) which includes a plurality of magnetic markers (10) disposed on a road surface for driving assist control of a vehicle (5) including automatic traveling control and in which a wireless tag is affixed to a partial magnetic marker (10A) of the plurality of magnetic markers (10), a sign (1M) for distinguishing between a partial magnetic marker (10A) with a wireless tag affixed thereto and another magnetic marker (10B) without a wireless tag affixed thereto is provided. Thus, it is possible to associate the detected magnetic marker (10) and the wireless tag as a transmission source of tag waves with each other with high reliability.

A mobile robot is configured for operation in a commercial or industrial setting, such as an office building or retail store. The robot can patrol one or more routes within a building, and can detect violations of security policies by objects, building infrastructure and security systems, or individuals. In response to the detected violations, the robot can perform one or more security operations. The robot can include a removable fabric panel, enabling sensors within the robot body to capture signals that propagate through the fabric. In addition, the robot can scan RFID tags of objects within an area, for instance coupled to store inventory. Likewise, the robot can generate or update one or more semantic maps for use by the robot in navigating an area and for measuring compliance with security policies.

The present disclosure provides a method for detecting a physical forbidden zone and global relocating of a service robot, the method comprising: presetting an identification on an edge of the physical forbidden zone that the service robot cannot enter in a working scenario; constantly detecting whether there is an artificial identification in the working scenario during operations of the service robot; identifying the artificial identification and confirming a position and heading angle information of the service robot relative to the artificial identification when there is artificial identification information in the working scenario; controlling a motion trajectory of the service robot according to the position and heading angle information of the service robot relative to the artificial identification to forbid the service robot from entering a respective physical forbidden zone.

A robotic garden tool may include a first sensor configured to sense an electromagnetic signal from a boundary cable installed on an operating surface, and a second sensor configured to sense a first anchor installed on the operating surface. The robotic garden tool may also include an electronic processor configured to control, based on first sensor data received from the first sensor, operation of at least one wheel motor to control movement of the robotic garden tool such that the robotic garden tool remains within a boundary defined by the boundary cable. The electronic processor may also be configured to, in response to receiving second sensor data from the second sensor that indicates a sensing of the first anchor, control operation of the at least one wheel motor to control movement of the robotic garden tool in a first predetermined manner.
