A point generating unit of a mobile terminal generates teaching point information associating a teaching position that teaches the work machine a position of the attachment in a series of movements to be performed by the work machine with orientation information indicating a target orientation at the teaching position, based on a slewing angle of an upper slewing body and on orientation information on the attachment. A point changing unit changes the generated teaching point information. When the teaching point information is changed, an instruction generating unit of the work machine generates an automatic operation instruction for automatically operating a slewing device and the attachment, based on the changed teaching point information. An operation control unit of the work machine automatically operates the slewing device and the attachment, based on the automatic operation instruction.

In the hydraulic excavator, the control unit outputs the drive signals, which gives the motion corresponding to the motion of the hydraulic cylinder, the revolving motor of the revolving unit and the traveling device to the work implement operating lever, the right work implement operating lever and the traveling lever, to the drive section. The control section outputs the control signals based on the motion of the left work implement operating lever the right work implement operating lever or the traveling lever operated by the operator when the motion of the left work implement operating lever, the right work implement operating lever or the traveling lever operated by the operator is different from the motion corresponding to the motion of the hydraulic cylinder, the revolving motor of the revolving unit and the traveling device.

A work machine capable of saving works by an operator during traveling is provided. The work machine includes a vehicular main body including a traveling unit, a work implement attached to the vehicular main body, and a controller that automatically controls operations by the work implement. The controller cancels automatic control of operations by the work implement based on a traveling state of the traveling unit.

Disclosed embodiments include power machines or loaders, and systems used on loaders, configured to augment the control of the loader to accomplish repetitive tasks. Also disclosed are methods of learning a task for augmented control of a loader, and methods of controlling a loader to perform a learned task to provide augmented control of the loader.

A shovel includes a hardware processor configured to record log information in a storage. The log information includes at least one of information on conditions surrounding the shovel and information on the conditions of the shovel at each of a time before, the time of, and a time after the occurrence of a predetermined event where at least one of the safety and the security of the shovel is relatively reduced.

A work vehicle including a chassis, a ground engaging implement configured to move the chassis along a ground surface, a boom connected to the chassis, an arm connected to the boom, and a bucket connected to the arm. A first actuator rotates the boom with respect to the chassis, second actuator rotates the arm with respect to the boom, and a third actuator rotates the bucket with respect to the arm. A processor calculates a first cycle time of operation of the first actuator, and analyzes if the calculated first cycle time is valid. If the first cycle time is valid, the processor communicates the calculated first cycle time to a user, and if the first cycle time is not valid, the processor repeats the calculation of the first cycle time of operation of the first actuator.

A shovel includes a lower traveling structure, an upper swing structure swingably mounted on the lower traveling structure, an attachment attached to the upper swing structure and including a boom, an arm, and a bucket, and processing circuitry. The processing circuitry is configured to cause the shovel to automatically perform work by causing the upper swing structure and the attachment to automatically operate. The work is at least one of the work of banking earth and the work of filling with earth.

Construction machinery with learning function includes an operating part having a working part, a manipulating part, a work-state detecting part, an operation-state detecting part, a reaction detecting part, a learning data memory configured to store a command outputted from the manipulating part in a time series as command data, and store, in a time series as estimation basic data, work-state data, operation-state data, and reaction data, a learning module configured to execute machine learning of command data stored in the learning data memory by using estimation basic data stored in the learning data memory, and, after the machine learning, receive an input of the estimation basic data during the operation of the operating part, and output an estimated command of the command, and a hydraulic drive system configured to drive the operating part based on one of the command and the estimated command, or both of the command and the estimated command.

A reproduction device includes an acquisition unit, a reception unit, and a reproduction unit. The acquisition unit acquires log information including angle information of a movable part of a work machine. The log information is associated with time. The reception unit receives a reproduction instruction usable to reproduce a movement of the work machine. The reproduction unit reproduces the movement of the work machine by sequentially applying the angle information to a work machine model upon receiving the reproduction instruction.

A convergence determination unit determines whether a state of the bucket has converged to a current target state. A target state update unit is configured to update a target state of the bucket when the convergence determination unit determines that the state of the bucket has converged to the current target state. The convergence determination unit includes a first convergence determination unit and a second convergence determination unit. The first convergence determination unit determines whether a swing angle of each mechanism has converged to the corresponding target swing angle under a first convergence condition. The second convergence determination unit determines whether a swing angle of each mechanism has converged to the corresponding target swing angle under a second convergence condition, which is stricter than the first convergence condition.
