Abstract: A time period for which an ineffective operation is performed during an excavation work is reduced. A work machine includes a vehicular body, a running wheel rotatably attached to the vehicular body, a work implement operable with respect to the vehicular body, an operation apparatus for operating the running wheel and the work implement, and a controller that controls an operation by the work machine. The controller determines that an ineffective operation in which the work implement does not work is being performed during the excavation work based on an operation command value output from the operation apparatus and outputs a time period for which the ineffective operation is being performed.

Abstract: A target posture for a work implement at work is determined. There is provided a working system, comprising a body, a work implement attached to the body, and a computer. The computer has a trained target posture estimation model to determine a target posture for the work implement to assume at work. The computer obtains a target value for an amount of a work performed by the work implement, a period of time elapsing since the work implement started to work, and mechanical data for operation of the body and the work implement, uses the trained posture estimation model to estimate a target posture from the target value, the elapsed period of time and the mechanical data, and thus outputs the estimated target posture.

Abstract: A manipulation system is provided that is used to guide an operator to manipulate a manipulation member. The manipulation system comprises a plurality of types of manipulation members manipulated by an operator of a work machine to operate the work machine, and a memory that stores model data for each type of manipulation member as a model in manipulating the manipulation members.

Abstract: An operator is allowed to easily recognize a difference between a manipulation actually performed when performing a work and a manipulation serving a model for the work. A manipulation guide device for a work machine includes a manipulation device, a storage unit, and a display unit. The manipulation device is manipulated by an operator of the work machine to operate the work machine. The storage unit stores model data serving as a model when the manipulation device is manipulated. The display unit displays a change over time in a result of comparison between actual manipulation data about an actual manipulation of the manipulation device by the operator and model data in a time period during an operation of the work machine.

Abstract: A work is classified into a type with high accuracy. A method for producing a work type estimation model trained comprises: obtaining training data including a specific viewpoint image, as viewed from a specific viewpoint position, of a three-dimensional model representing a stereoscopic shape of a work machine at work, and a result of classifying a work into a type with which the specific viewpoint image is labeled and which indicates content of a motion of the work machine; and training the work type estimation model through the training data.

Abstract: An image clearly displaying a work machine is easily obtained. A posture data generation unit estimates a posture of a work implement with respect to the body of the work machine in a captured image displaying the work machine. A motion state image generation unit creates a three-dimensional model representing a stereoscopic shape of the work machine based on the posture of the work implement. A specific viewpoint image generation unit creates image data including a two-dimensional image of the three-dimensional model, as viewed at a viewpoint position indicating a position of a viewpoint at which the three-dimensional model is virtually viewed.

Abstract: A display system of a wheel loader includes an obtaining unit that obtains work machine motion information including an articulation angle, a motion image generator that generates a motion image including an articulated state of the wheel loader based on the work machine motion information obtained by the obtaining unit, and a display that shows the motion image.

Abstract: A time period for which an ineffective operation is performed during an excavation work is reduced. A work machine includes a vehicular body, a running wheel rotatably attached to the vehicular body, a work implement operable with respect to the vehicular body, an operation apparatus for operating the running wheel and the work implement, and a controller that controls an operation by the work machine. The controller determines that slip-during-excavation which refers to slip of the running wheel with respect to the ground is occurring during the excavation work based on an operation command value output from the operation apparatus and outputs a signal relating to working of the work implement.
