A work machine includes an unload lever swingably supported by an operation box, the unload lever being configured to be swung to select whether or not to supply an operation fluid to the hydraulic actuator. The unload lever includes a second guide pin to move in a first guide groove in accordance with the swinging of the unload lever, the second guide pin being positioned on a first end of the first guide groove when the unload lever is positioned to a pushed-down position and positioned on a second end of the first guide groove when the unload lever is positioned to a pulled-up position. The first guide groove includes a first latch portion to latch the second guide pin at the first end of the first guide groove, and a second latch portion to latch the second guide pin at the second end of the first guide groove.

The invention relates to a method for dredging an underwater bottom in an area using a dredging device. The method includes: determining the present positions of the dredging device and of a source of contamination in the area; entering input data relating to the area into a hydrodynamic model of the area; determining with the hydrodynamic model the degree of contamination at positions in the area resulting from spread of the contamination from the source; comparing the degree of contamination at positions in the area to a threshold value for these positions; and optionally adapting the dredging if the degree of contamination exceeds the threshold value. Underwater bottom can be dredged using the invented method, such that on the one hand the production is maximized and on the other the consequences for the natural environment are minimized.

A perception system for an autonomous machine to be hauled by a towing vehicle includes sensors that are configured to determine characteristics of an environment associated with the machine. Such characteristics associated with the machine include at least structural characteristics of the towing vehicle. The sensors are further configured to detect a presence of the towing vehicle on a job site, an orientation of the towing vehicle on the job site, and a loading end of the towing vehicle. The perception system further includes a controller that is communicably coupled to each of the sensors. The controller is configured to actuate movement of the machine in relation to the towing vehicle based on the characteristics of the environment determined by the sensors.

A control system implemented for in-pit crushing and conveying (IPCC) operations employing a shovel machine and a crusher machine is provided. The shovel machine includes an implement configured to excavate a material from a worksite and load the material into a hopper of the crusher machine. The control system includes a position determination module, an excavation determination module, and a path determination module. The path determination module is configured to determine one or more travel paths, with a plurality of loading positions, for the shovel machine and the crusher machine. The plurality of loading positions is based at least in part on the relative position of the shovel machine and the crusher machine and a plurality of excavation positions, such that at each of the plurality of loading positions, the implement traverses an arc passing above the hopper.

A compactor machine includes a machine frame, at least one cylindrical roller drum rotatably coupled to the machine frame and rotatable about a drum axis oriented generally transverse to a direction of travel of the compactor machine, and a first light attached to the machine frame, the light shining a line of light on a surface that indicates a location of an edge of the roller drum.

An undercarriage clearance system includes a datastore containing undercarriage geometry data including ground clearance data of the undercarriage assembly across a lateral dimension of a wheelbase of the work vehicle; a first sensor configured to collect ground environment data within the vehicle trajectory; and a controller. The controller is configured to: receive the undercarriage geometry data from the datastore; receive the ground environment data from the first sensor; identify an obstacle within the vehicle trajectory; evaluate a height of the identified obstacle and a projected path of the obstacle within the wheelbase of the work vehicle along the vehicle trajectory relative to the undercarriage geometry data to determine an obstacle clearance expectation; and generate an alert command signal based on the determination of the obstacle clearance expectation. A display device is configured to render a display based on the alert command signal representing the obstacle clearance expectation.

The present disclosure relates to a computer implemented method for operating a control system to form a travelling path for a vehicle, where the path determination is based on data generated by a pair of sensors producing three-dimensional (3D) point clouds, where the 3D point clouds respectively provide a representation of a left and a right hand side of the vehicle. The present disclosure also relates to the corresponding control system and to a computer program product.

The present invention enables generating a desired target travel path intended by a user or the like without the need for various input works for the type, width, and the like of a work machine. The present invention is provided with: a travel path generation unit which generates a target travel path (P) along which a work vehicle is caused to travel automatically; and a reference point setting unit which, on the basis of position information about the work vehicle when the work vehicle has been caused to travel, sets a first reference point (A) and a second reference point (B) for generating a first reference line, and a third reference point (C) for setting intervals, wherein the path generation unit generates, as the target travel path (P), a path that includes a plurality of parallel paths (P2) parallel to the first reference line (P1) based on the first reference point (A) and the second reference point (B), and sets respective intervals between the first reference line (P1) and the parallel paths (P2) and also each interval between the parallel paths (P2), on the basis of a distance between the second reference point (B) and the third reference point (C).

A machine navigation system includes a monitoring mechanism for monitoring configuration of an implement movable between configurations relative to a frame such that a center of mass of the machine moves in response to the moving of the implement. A second monitoring mechanism monitors track speed in the machine. A location of an origin of the track speed varies based upon location of the center of mass. A control unit is coupled with the monitoring mechanisms and structured to determine a control term for compensating for movement of a reference location on the machine relative to the track speed origin. The control unit further calculates velocity based on the track speed and the compensatory control term.

The travel control system includes: a travel zone holding unit configured to hold a travel zone which is set in a particular travel area set beforehand and over which a dump truck is to autonomously travel; a target position setting unit configured to set, on an outer side of the particular travel area, a target position that the dump truck is to reach; a distance measurement unit configured to measure a traveling distance of the dump truck from a position of the dump truck as acquired using a position acquisition device provided in the dump truck to the target position set by the target position setting unit; and an autonomous travel control unit configured to control the dump truck so that the dump truck moves to an outer side of a travel zone held by the travel zone holding unit and autonomously travels the traveling distance.
