A management system of a work site includes a sprinkling data generation unit and an assignment unit. The sprinkling data generation unit is configured to generate sprinkling data indicating a sprinkling condition of a sprinkling vehicle at the work site. The assignment unit is configured to, when receiving a transport request of an operator, output a transport command for causing the sprinkling vehicle operating based on the sprinkling data to travel to a destination position.

The invention discloses an unmanned aerial vehicle having multifunctional leg assembly and charging system, including unmanned aerial vehicle and charging station. The UAV includes obstacle avoidance sensors, flight control module, first signal processing module, electric undercarriage and power charge/storage module. The charging station includes power charge/supply module. The obstacle avoidance sensors sense obstacles near the UAV to generate obstacle sensing signals. The first signal processing module interprets and processes the obstacle sensing signals to determine whether there is an obstacle near the UAV, and when the judgment result is yes, an avoidance instruction is transmitted to the flight control module, so that the flight control module drives the UAV to avoid the obstacle. The electric undercarriage includes first leg frame, second leg frame and electric driving mechanism. The electric driving mechanism drives the first leg frame and the second leg frame to fold and unfold alternately. The power charge/storage module includes first positive electrode and first negative electrode. The charging station includes power charge/supply module. The power charge/supply module includes second positive electrode and second negative electrode. When the UAV parks on a platform of the charging station, and the first positive electrode and the first negative electrode are in contact with the second positive electrode and the second negative electrode, then the power charge/supply module charges electricity to the power charge/storage module.

A mobile printing robot prints layouts or other construction information on a construction surface. Support is provided for precise line navigation in a single pass or parallel passes. A firing pattern of an array of printing nozzles may be selected to compensate for lateral errors in position. The mobile printing robot may also print fiducial marks as an aid for navigation.

A remote operation support system and method that can improve spatial recognition accuracy by an operator who remotely operates work machine is provided. A captured image representing a sight around work machine (40) is captured by an imaging device (412b) mounted on the work machine (40). A synthetic image is generated by superimposing an index image representing an index member positioned in a cab (454) (operator's room) of the work machine (40) in a pseudo manner on the captured image. The synthetic image is displayed on a remote output interface (220) of a remote operation device (20) that allows remote operation of the work machine (40).

Solution: Provided is an operation plan generation device which generates information indicating an operation plan for a working machine which drives using electrical power to perform a predefined work by the working machine.

The operation plan generation device acquires working location information including route information indicating a drivable path set on a map for the working machine in a working location where the working machine engages a work; acquires information indicating a condition regarding power-feeding equipment that can feed electrical power to the working machine installed in the working location; based on the working location information and a plurality of conditions different from each other, each condition being identical to the condition, generates information indicating the operation plan in each of the plurality of conditions.

A system is provided which can achieve reliability of a notification about a moving manner of a work machine for a worker regardless of the distance between the work machine and the worker. A sign image M is projected onto a peripheral region of the worker (for example, a ground surface which is present in the vicinity of the worker to the extent that the worker is capable of visually recognizing the sign image M) by an unmanned aircraft 60. The sign image M is an image which represents a moving manner of a work machine 40. Thus, regardless of the distance between the work machine 40 and the worker, reliability of a notification about the moving manner of the work machine 40 for the worker is achieved compared to a case where the sign image M is projected onto an irrelevant place to the position of the worker.

A system for generating a work plan for autonomous operation of a compactor in tandem with an earthmoving machine includes a first controller that receives information pertaining to a work area on which the earthmoving machine is required to perform at least one operation. The system also includes a central controller that receives, from the first controller, information pertaining to the work area on which the compactor is required to perform the at least one operation and analyzes the work area for virtually segmenting the work area into a plurality of virtual work areas, and data indicative of a movement of the earthmoving machine through each virtual work area from the plurality of virtual work areas. The central controller determines an optimal direction of movement for the compactor based on the data indicative of the movement of the earthmoving machine, topographical conditions, as well as geometry of the work area.

To assist operation of a perception-based location and navigation system, a computer-implemented system and method can determine if a physical marker at a worksite is perceptibly obstructed. Worksite data can be gathered from the physical worksite and/or a worksite map in computer readable format. The worksite data is analyzed with respect to the worksite map to determine if the physical marker is obstructed. To resolve the marker obstruction, an obstruction resolution can be generated and output.

A system for autonomous or semi-autonomous operation of a vehicle is disclosed. The system includes a machine automation portal (MAP) application configured to enable a computing device to (a) display a map of a work site and (b) provide a graphical user interface that enables a user to (i) define a boundary of an autonomous operating zone on the map and (ii) define a boundary of one or more exclusion zones. The system also includes a robotics processing unit configured to (a) receive the boundary of the autonomous operating zone and the boundary of each exclusion zone from the computing device, (b) generate a planned command path that the vehicle will travel to perform a task within the autonomous operating zone while avoiding each exclusion zone, and (c) control operation of the vehicle so that the vehicle travels the planned command path to perform the task.

According to some aspects of the disclosure, a path generation apparatus for generating a movement path of at least one drone for inspection of an object, the path generation apparatus comprises a problem solving unit configured to output a solution by solving a vehicle routing problem model by using a metaheuristic technique with respect to a graph in which a connection relationship among a plurality of checkpoints included in the object is defined as a target and a path generation unit configured to generate the movement path of the at least one drone based on the outputted solution.
