A work machine includes a chassis, a wheel, an implement, a user interface, and a utilization monitoring system. The wheel is rotatably coupled to the chassis. The implement is movable relative to the chassis. The user interface is configured to receive a user input. The utilization monitoring system includes one or more memory devices configured to store instructions thereon that, when executed by one or more processors, cause the one or more processors to obtain one or more values representing an operational range of the implement; receive the user input; determine a value representing a position of the implement; and determine a value representing a utilization of the implement by comparing the position of the implement to the one or more values representing the operational range of the implement.

A computer-implemented method of operating an implement for a work machine as disclosed herein includes a calibration mode and an operation mode. In the calibration mode: at least one of one or more components of the implement may be rotated about at least one linkage joint corresponding to the at least one of the one or more components into one or more poses; for the one or more poses, the implement may be revolved about a frame of the work machine; output signals may be received from at least one sensor associated with the at least one of the one or more components; and at least one characteristic for the at least one of the one or more components may be tracked. In the operation mode, movement of the at least one of the one or more components may be based in part on the tracked at least one characteristic.

A work machine controller that is coupled to the boom assembly may comprise of a controller with a memory that stores computer-executable instructions and a processor that executes instructions. The instructions include monitoring a first position signal from the first boom position sensor, a second position signal from the second boom position sensor, the load signal, and the orientation signal. The instructions then include calculating a load vector based on the load signal and the orientation signal, generating a disorientation signal based on the load vector and a direction of travel, determining if the disorientation signal is outside a predetermined threshold, and actuating one or more of the actuators and the ground-engaging mechanism to reorient the load when the disorientation signal exceeds the predetermined threshold.

A ripper device includes a first cylinder, a shank, and an arm. The first cylinder includes a tube and a rod, and is disposed to extend and retract in the forward and backward direction in a plan view of the ripper device. The shank is disposed aligned with the first cylinder in the forward and backward direction in the plan view. The arm supports the shank and overlaps the tube of the first cylinder in the plan view.

An excavator includes a machine guidance device having a machine guidance function, wherein the machine guidance function performs voice sound guidance by emitting a report sound when a region of work by an end attachment approaches a predetermined distance to an excavation target surface, and performs the voice sound guidance by emitting a report sound when the region of work by the end attachment approaches a predetermined distance to an extension surface, also in an area along the extension surface set in an extended direction from the excavation target surface.

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.

Methods for commissioning a construction vehicle for machine control operations are provided. A GNSS receiver configured for determining position information, tilt information, and heading information is coupled to a rigid member of the construction vehicle. The commissioning process provides parameters that can be used for tracking and controlling movement of an implement coupled to the construction vehicle during the machine control operations.

A construction machine includes: a work device attached to a machine body in a raiseable and lowerable manner; an antenna that is attached to the machine body and receives positioning signals from satellites; a machine body IMU that senses information on a posture and motion of the machine body; an IMU that senses information on a posture of the work device; and a computing device that computes posture information indicating the postures of the machine body and the work device. The computing device performs positioning computation to compute a position of the machine body and a variance value thereof based on the positioning signals received by the antenna, subjects the position as a result of the positioning computation to first smoothing processing that is to increase a degree of smoothing as the variance value as a result of the positioning computation becomes larger, and computes the posture information.

A remote operation device and a remote operation system that can reduce or eliminate deviation of the position of an indicator image of a working unit such as a line image in an image with respect to the position of the working unit in a real space. In some case, because of a cause such as a communication failure, a position posture coordinate value of a working unit corresponding to captured image data in a work environment image deviates from a position posture coordinate value of the working unit estimated according to an operation form of a remote operation mechanism. In this case, a semitransparent indicator image Img2(τ2) simulating a bucket is superimposed on a work environment image Img1(τ2) in a position where the bucket is estimated to be originally present and deviating from an image region representing the bucket.

A shovel includes a lower traveling body, an upper turning body turnably mounted on the lower traveling body, a cab mounted on the upper turning body, a display device provided in the cab and configured to display a setting screen associated with work assistance, an audio input device provided in the cab, and a hardware processor configured to perform audio recognition. The hardware processor is configured to recognize speech input through the audio input device and executes a process related to the setting screen according to a recognition result.
