A pipe-laying system and method includes assessing an environment and placing of a pipe from an excavator to a trench. The system comprises a frame, a boom assembly, and an implement. The boom assembly includes a large boom and a dipper stick. The implement is detachable coupled to the dipper stick and moveable relative to the dipper stick. The system also includes at least one sensor operable to sense a position or a direction of movement of the large boom, dipper stick, or implement. The system also includes a stereo camera to obtain visual data. A controller is adapted to receive the visual data signal, identify an edge of the pipe, receive a signal from the sensor, associate the visual data with corresponding data, create visual feedback and an input signal the position of the boom assembly.

At least a portion of a first target design topography is positioned below an actual topography. At least a portion of a second target design topography is positioned below the actual topography and is inclined with respect to the first target design topography. A controller generates a command signal to operate a work implement according to the first target design topography in an area where the first target design topography is positioned above the second target design topography. The controller generates a command signal to operate the work implement according to the second target design topography in an area where the second target design topography is positioned above the first target design topography.

A control system for the work vehicle includes a display, an input device, and a controller. The controller displays a current position of a work vehicle on a screen of a display. The controller receives a first input signal indicating an input operation by an operator from a input device. The controller determines, as a first position, the position of the work vehicle when the first input signal is received. The controller displays the first position on the screen of the display. The controller receives a second input signal indicating an input operation by an operator from the input device. The controller determines, as the second position, the position of the work vehicle when the second input signal is received. The controller determines a target design surface indicating a target trajectory of a work implement based on reference position information including at least the first position and the second position.

Systems and methods are disclosed herein for controlling cooling fans in a self-propelled work vehicle having a main frame supported by wheels or tracks. The cooling fans direct ambient air in accordance with at least one inlet in the main frame, and selectively operate in first and second opposing directions. A perception system is supported by the main frame and configured to provide perception data (e.g., perception data) corresponding to a field of vision which includes the at least one inlet and at least a portion of an associated working area. A controller obtains the perception data and automatically determines characteristics relating to contamination of the cooling system based at least On the perception data. The controller further generates output signals to the cooling fans based on at least one of the determined contaminant characteristics, for example a debris location, type, density, and/or quantity as relating to contamination of the cooling system.

A vehicle moves through an environment (e.g., a farming, construction, mining, or forestry environment) and performs one or more actions in the environment. Portions of the environment may include moisture, such as puddles or mud patches. A control system associated with the vehicle may include a traversability model or a moisture model to help the vehicle operate in the environment with the moisture. In particular, the control system may employ the traversability model to reduce the likelihood of the vehicle attempting to traverse an untraversable portion of the environment, and the control system may employ the moisture model to reduce the likelihood of the vehicle performing an action that will damage a portion of the environment.

A controller mounted in a work machine limits a velocity at which a work device approaches a design surface to be equal to or lower than a predetermined limiting velocity in such a manner that the work machine is located above the design surface when an operation device is operated. The controller determines whether a work phase of the work device is compaction work on the basis of a posture of a bucket with respect to the design surface in a case in which the operation device instructs the work device to approach the design surface, and sets the limiting velocity when determining that the work phase of the work device is the compaction work to be higher than the limiting velocity when determining that the work phase of the work device is other than the compaction work.

A control system for a work vehicle includes at least one sensor, an operating device, and a controller. The operating device includes at least one operating member. The controller is programmed to control a work implement of the work vehicle based on signals from the at least one sensor and the operating device. The controller is further programmed to use the signals to obtain a distance between the work implement and a design terrain which represents a target shape of a work object, and to determine whether a surface compaction determination condition indicating that work performed by the work implement is surface compaction work is satisfied. The controller executes a surface compaction control in which a velocity of the work implement toward the design terrain is limited in response to the distance between the work implement and the design terrain when the surface compaction determination condition is satisfied.

An excavator includes a machine guidance device having a machine guidance function, wherein the machine guidance function sets a standard surface at a position closer to a ground surface than an excavation target surface, compares a height of a region of work by an end attachment with a height of the standard surface, and performs guidance by a report sound based on a result of the comparison.

An overhead-view image of a work site is presented to an operator of a work machine even when the number of imaging devices at a construction site is lacking. The present disclosure provides an information presentation device for generating and outputting a terrain image relating to a construction site. The information presentation device includes a storage device that stores a program for performing a predetermined imaging process on the terrain image, and a processor for reading the program from the storage device and generating the terrain image. The processor performs: a process of using an image of the construction site acquired by at least one imaging device installed at a construction site, to acquire a first overhead-view image representing a current terrain of the construction site as viewed from above; a process of acquiring a second overhead-view image acquired by a method other than capturing by the imaging device installed at the construction site, and representing an original terrain of the construction site as viewed from above; and an image synthesis process of superimposing the first overhead-view image and the second overhead-view image to generate a first synthesized overhead-view image.

A controller acquires a static path indicative of a target route of a transport vehicle. The static path includes a first endpoint and a second endpoint. The static path is set between a first work machine and a second work machine. The controller determines a first dynamic path that connects the first endpoint and a first target position for work of the first work machine. The controller determines a second dynamic path that connects the second endpoint and a second target position for work of the second work machine. The controller controls the transport vehicle so that the transport vehicle travels according to the static path, the first dynamic path, and the second dynamic path.
