A control device outputs an operation signal of a work equipment and a swing body for moving a work equipment to a loading point when receiving a loading command signal. The control device does not output a dumping operation signal for causing the bucket to dump earth in a case where an azimuth direction in which the swing body faces is within a first region from a starting point azimuth direction to a predetermined reference azimuth direction, the starting point azimuth direction being an azimuth direction in which the swing body faces when the loading command signal is received. The control device outputs the dumping operation signal in a case where the azimuth direction is within a second region from the reference azimuth direction to an end point azimuth direction in which the swing body faces when the work equipment is positioned at the loading point.

An excavator includes a lower traveling body; an upper turning body turnably mounted to the lower traveling body; an actuator configured to drive a driven part including the lower traveling body and the upper turning body; and a power storage device mounted in the upper turning body and configured to serve as an energy source for driving the actuator. The power storage device includes a plurality of power storage modules stacked in a vertical direction, each of the plurality of power storage modules including a power storage part and a housing configured to house the power storage part. The housings of power storage modules among the plurality of power storage modules that are adjacent to each other in the vertical direction, are coupled to each other.

A remote driving device (100) includes an operation lever (1) to be operated based on an operation command signal, and a first operation mechanism (30) which tilts the operation lever (1). The first operation mechanism (30) includes a first actuator (31) which generates a driving force to tilt the operation lever (1) based on the operation command signal, a first transmission device (41) which transmits the driving force of the first actuator (31), a first detector (61) which detects a tilting amount of the operation lever (1), and a first drive shaft (51). On the first drive shaft (51), a first rotation output part (52) is provided, and the first drive shaft rotates with the tilting of the operation lever (1). The first detector (61) detects the tilting amount of the operation lever (1) via the first rotation output part (52).

A work tool identification system for identifying the work tool attachment attached to a machine from among a plurality of interchangeable work tool attachments utilizes a data transmission device located on the work tool attachment and an electronic machine controller that may be located on the machine. The data transmission device may store work tool identification data and may measure an interval count indicative of the lapsed time since the work tool attachment was initially moved by a machine. The electronic machine controller generates and sorts a work tool identification list of the plurality of work tool attachments based on the interval count with the lowest interval count appearing before any higher interval counts that is indicative of a recently coupled work tool.

A method of controlling a work machine, includes: accepting an operation for an operation unit for controlling a work machine; monitoring a specific event to be monitored; and determining, with the specific event occurring, whether or not a determination condition for the operation for the operation unit is met.

A method includes receiving a worksite plan to be executed by at least one machine at a worksite from a computing device of a supervising entity, the controller being located at a non-line-of-sight (NLOS) location with respect to the worksite. The worksite plan may include a boundary of the worksite at which the worksite plan is implemented, at least one task defining the worksite plan, and a selection of at least one machine to perform the task. The method may include receiving a validation signal from a device located at the worksite, the validation indicating that the worksite is ready for implementation of the worksite plan based on at least one parameter of worksite readiness. The method may include selecting a first mode of operation of the machine to perform the task and transmitting first instructions to the machine to perform the task based on the first mode of operation.

An objective is to provide a remote operation assistance device 100 enabling an operator to get a feel for the controls of a work machine 40 before communication is established between a remote operation device 20 and the work machine 40. To achieve the objective, the remote operation assistance device 100 as configured includes a first assistance processing element 101. The first assistance processing element 101 executes a control for displaying, on a remote output interface 220, a simulated environment image for simulating remote operation of the work machine 40.

In a construction method using an excavator that is controlled by manual operation, and an excavator that includes an automatic working-equipment control unit automatically controlling second working equipment on the basis of at least one of a current terrain and a designed terrain of a construction range in a construction site, and a tooth-edge position of the second working equipment, a progress rate that indicates a volume of soil having been excavated by the excavator to a target volume of soil to be excavated by the excavator in the construction range is calculated, and when the progress rate is equal to or larger than a threshold, the excavator stops construction of the construction range, and the excavator takes over the construction of the construction range, from the excavator.

A work vehicle includes a work implement. A control system for the work vehicle includes an operating device and a controller. The operating device outputs an operation signal indicative of an operation by an operator. The controller communicates with the operating device and controls the work implement. The controller determines a first target design topography. The controller generates a command signal to operate a work implement in accordance with the first target design topography. The controller obtains a displacement amount of the work implement with respect to the first target design topography upon receiving the operation signal indicative of the operation of the work implement during work in accordance with the first target design topography. The controller determines a second target design topography based on the displacement amount. The controller generates a command signal to operate the work implement in accordance with the second target design topography.
