An electronic processor is configured to receive image data captured by the optical sensor, apply an artificial neural network to identify a ground material characteristic based on the image data from the optical sensor, wherein the artificial neural network is trained to receive the image data as input and to produce as the output an indication of the ground material characteristic, access, from the non-transitory computer-readable memory, the operation information corresponding to the ground material characteristic, and adjust an operation of the work vehicle based on the accessed operation information corresponding to the ground material characteristic.

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.

A shovel includes a plurality of driven elements, a plurality of actuators configured to drive the plurality of driven elements, and a hardware processor configured to, in response to detecting that two or more actuators of the plurality of actuators are synchronously moved, prohibit a motion of another actuator of the plurality of actuators that is different from the two or more actuators of the plurality of actuators.

A work vehicle includes a work implement. A control system for the work vehicle includes a controller that controls the work implement. The controller obtains a first design topography. The controller determines a second design topography. At least a portion of the second design topography is positioned above the first design topography. The controller generates a command signal to operate the work implement in accordance with the second target design topography. The controller changes a tilt angle of the work implement when at least a portion of the second design topography is positioned below the first design topography.

A work vehicle a computing system configured to receive first and second input associated with controlling the operation of the first and second hydraulic load, respectively. Furthermore, the computing system is configured to control the operation of a first or second flow control valve corresponding to the one of the first or second hydraulic loads associated with the greater hydraulic fluid pressure such that the corresponding adjustable orifice is at a maximum flow position. Additionally, the computing system is configured to determine the first and second pressures of the hydraulic fluid being supplied to the first or second hydraulic loads. Moreover, the computing system is configured to control the operation of the first or second flow control valve corresponding to another of the first or second hydraulic loads based on the corresponding received first or second input and the determined first and second pressures.

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.

A remote control console or operator's station includes a proportional travel control joystick that effects continuous changes in machine travel speed through movement of the joystick away from a central-biased position, a sensor that measures progressively changing positions of the joystick, and an electronic controller communicatively coupled to the sensor and the joystick. The electronic controller is programmed to perform a closed loop control including mapping the progressively changing positions of the joystick to corresponding desired machine travel speeds, and adjusting the speeds of an engine used to propel the machine and the amounts of service braking used to slow the machine to achieve desired machine travel speeds.

There is provided a technology capable of, when a remote operation target through a remote operation apparatus is switched from one work machine to another work machine, making it easy for an operator to respond to an environmental change of the remote operation target. A first work environment image based on first picked-up image data acquired through a work machine image-pickup device 412 of a first work machine which is a current remote operation target of a remote operation apparatus 20 is outputted on a remote output interface 220. In addition, a second work environment image based on second picked-up image data acquired through a work machine image pickup apparatus of a second work machine which is the next remote operation target of the remote operation apparatus 20 is outputted on the remote output interface 220.

An automatic control determination unit determines whether to start automatic dumping control. A dumping control unit generates a first command to rotate a bucket in a dump direction until an inclination of the bucket reaches a predetermined dumping completion angle upon determining to start the automatic dumping control. The dumping control unit generates a second command to rotate a boom in a raising direction during a period until the inclination of the bucket reaches the dumping completion angle from an inclination at the time of start of the automatic dumping control.
