Microdredging systems comprising a pumping platform and loading platform. In certain embodiments, system operates autonomously and is adapted to allow the loading platform undock from the pumping platform for disposal of the removed sediment.

The work state identifying unit identifies a work state of a work machine disposed in a construction site at each time point and a work state of a transport vehicle traveling at the construction site at each time point. The time chart generation unit that generates a time chart representing the work state of the work machine at each time point and a time chart representing the work state of the transport vehicle at each time point on the basis of the identified work states. The output control unit that outputs the time charts on an identical screen with a time axis as a common axis.

A control device that controls a work vehicle including work equipment includes: a route acquisition unit that acquires a traveling route of a transport vehicle; an area setting unit that sets a limit area for limiting entry of the work equipment along the traveling route; and a signal output unit that outputs a signal for controlling the work vehicle or the transport vehicle on the basis of a relationship between the limit area and the work equipment.

Systems and methods of restoring a lake including dredging, island creation, water treatment, real estate development, computer modeling of environmental conditions, wave height reduction, sediment removal and encapsulation, bathymetry contouring, littoral zone restoration, plant restoration, and/or fish restoration.

A mining machine is disclosed. The mining machine may include a mobile ranging device, a movement sensor device, and a control unit. The mobile ranging device may be configured to communicate with a location sensor device and cause the location sensor device to transmit location data relating to a location of the mining machine. The movement sensor device may be configured to transmit movement data relating to a movement of the mining machine. The control unit may be configured to receive coordinate data relating to a plurality of zones and a plurality of drawpoints of a tunnel, the location data, and the movement data. The control unit may identify an active zone, determine a machine heading, determine a machine articulation, identify an active drawpoint based on the active zone, the machine heading, or the machine articulation, and cause an action to be performed in connection with the active drawpoint.

A worksite controller can automatically track movement of material on a worksite, based on location information and work event information provided by vehicles on the worksite. The worksite controller can determine and/or use a location of a work tool of a vehicle, rather than coordinates determined by a location sensor mounted elsewhere on the vehicle, to determine when the work tool is located within defined boundaries of work zones associated with material. When the worksite controller determines that the vehicle performed a work event to interact with material while the work tool was within a particular work zone, the worksite controller can automatically update material tracking information associated with the work zone.

Methods, systems, and apparatus are described herein for providing operational efficiency at a construction site through a connected system of on-board mobile computers.

A system, method, and apparatus can access, via a user interface, route properties of a mine site used for controlling one or more work machines as the work machine(s) travel through the mine site. Access regarding the route properties can include viewing one or more of the properties and/or setting requirements (e.g., restrictions or limitations) for one or more of the properties. A candidate route can be selected, validated, and set as a selected route using the user interface to access route properties associated with the selected route. Requirements can be set for one or more of the route properties using the user interface. The work machines can be controlled to traverse the mine site according to the requirements set for the route properties.

A system and method for dispatching haul trucks includes a production planner configured to operate based on a production plan. The production planner computationally defines production arcs for transferring material from loading tools to dump sites, computationally develops one or more possible return arcs for each production arc, compiles a set of possible return arcs, and computationally selects a sub-set of the possible return arcs to command a real time dispatcher.

A loaded machine information acquisition unit acquires position information and azimuth direction information of a transport vehicle. An earth removal position-specifying unit specifies an earth removal position for loading a load target onto the transport vehicle, based on the position information and the azimuth direction information. A bucket position-specifying unit specifies a position of a bucket. An operation signal generation unit generates an operation signal for moving the bucket from the specified position to the earth removal position.
