A safety device includes a contour sensor which acquires contour data representing a contour of a landform around a hydraulic excavator; a determination part which determines, based on the contour data, whether the landform satisfies an execution criterion of executing a turning-over prevention control for preventing the hydraulic excavator from being turned over to a slope extending in a specific direction therearound; and a lowering control part which lowers a leading end of a working device to the slope when the determination part determines that the execution criterion is satisfied.

A system for moving material from a first location to a second location includes a planning system to identify an initial spot location. A perception sensor is configured to generate perception signals indicative of whether an obstacle is in the path between a material carrying machine and the initial spot location. An alternate spot location is determined if an obstacle is in the path and a propulsion command is generated to move the material carrying machine from the current pose to the alternate spot location.

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.

A shovel including a lower-part traveling body, an upper-part swiveling body which is enabled to swivel and is mounted to the lower-part traveling body, an actuator, and a control device that implements a first control process that causes the actuator to act autonomously, and a second control process that causes the actuator to act autonomously, wherein the control device is configured to select one control unit from among a plurality of control units that implements the first control process and the second control process, as a priority control process that is given priority to act, in a case where a conflict is judged to occur among the plurality of control units that implements the first control process and the second control process.

A shovel includes a lower traveling body, an upper turning body turnably mounted on the lower traveling body, an attachment attached to the upper turning body, an attachment actuator configured to move the attachment, and processing circuitry configured to assist an operator so that a level difference between two adjacent finished surfaces becomes equal to or less than a predetermined value.

Provided is a hydraulic excavator (1) that performs work by operating an arm (9) after moving a bucket (10) to a work start position. An operation determination section (81c) determines, based on an operation performed on an operation device, whether a front work device (1A) is engaged in a work preparation operation for moving the bucket to the work start position. When the operation determination section determines that the front work device is engaged in the work preparation operation at the time of operation of the operation device, an actuator control section (81) controls a bucket cylinder (7) such that the angle of a work tool with respect to a target surface coincides with a preset target angle (θTGT).

A controller is installed in a work machine and configured to perform loading control based on a detection result of a position detection unit. An external system is arrangeable outside the work machine and communicable with the controller. The external system is configured to output a loading control start signal for starting the loading control. The controller starts the loading control on condition that the loading control start signal has been input from the external system to the controller.

Upon determining that the work apparatus will not enter a prohibited area set on the basis of output of a second position calculator of a carrier, the system computes, on the basis of the result of a prediction computation, first input of the dynamic characteristic with which a distal end of the work apparatus approaches a target position set on the basis of the output of the second position calculator. Upon determining that the work apparatus will enter the prohibited area, the system computes second input of the dynamic characteristic with which the distal end targets and approaches a position that is closer to the target position than the position of the distal end of the work apparatus at a position different from the target position outside the prohibited area, and the system computes control input for controlling the operation of the loader.

A movement processing unit is configured to generate operation signals of a work equipment and a swing body for moving a bucket to a loading point based on a start command of an automatic movement of the bucket. A stop processing unit is configured to brake a swing of the swing body based on a stop command of the automatic movement of the bucket, and is further configured to generate an operation signal for retreating the work equipment when a height of the bucket is lower than the loading point.

Embodiments described herein provide for the control of an industrial machine dump operation by monitoring a position of the piston within a dump cylinder. The position of the piston is determined using a sensor within the dump cylinder. The sensor generates and provides an output signal to a controller. Based the output signal from the sensor, the controller is configured to limit the travel of the dump cylinder during the dump operation to reduce wear on the dump cylinder (e.g., by preventing damage caused when the dump cylinder is extending or retracting rapidly and the internal cylinder components make forceful contact with the rod or cap end).
