This description provides an autonomous or semi-autonomous excavation vehicle that is capable of navigating through a dig site and carrying out an excavation routine using a system of sensors physically mounted to the excavation vehicle. The sensors collects any one or more of spatial, imaging, measurement, and location data representing the status of the excavation vehicle and its surrounding environment. Based on the collected data, the excavation vehicle executes instructions to carry out an excavation routine. The excavation vehicle is also able to carry out numerous other tasks, such as checking the volume of excavated earth in an excavation tool, and helping prepare a digital terrain model of the site as part of a process for creating the excavation routine.

A work machine includes a work device having a boom, an arm, and work equipment and a controller that sets a target surface, and calculates a work equipment-to-target surface distance on the basis of signals from a position sensor and a posture sensor, and controls the boom and carries out deceleration control to decelerate the arm to keep the work equipment from excavating ground beyond the target surface when operation of the arm is carried out and the work equipment-target surface distance has become shorter than a predetermined distance. The controller determines whether or not there is a possibility that the work equipment enters the target surface when operation of the arm is carried out based on the set target surface and the signals from the position sensor and the posture sensor, and does not carry out the deceleration control even when the work equipment-to-target surface distance is shorter than the predetermined distance in the case in which it is determined that there is no possibility that the work equipment enters the target surface.

The present disclosure provides a work machine capable of providing operation assistance matching an operator's intent in consideration of a rotating motion. A control device 80 includes a storage device 81 and a central processing device 82. The storage device 81 has stored therein construction target information for a work device 10 and determination criteria information for the work content of the work device 10 based on the amount of operation of a rotating device 30. The central processing device 82, based on the position and attitude of the work device 10 detected by a sensor 60, the amount of operation of the rotating device 30 detected by an operation amount detection device, and the determination criteria information stored in the storage device 81, determines the work content of the work device 10, calculates a correction value for the construction target information based on the determined work content, and controls a drive device 50 based on the construction target information and the correction value to assist an operation by an operator.

A controller may receive information identifying an area of interest from a plurality of candidate areas of interest including locations on the machine and external to the machine. The controller may obtain, using the one or more first sensor devices, data identifying material located at the area of interest; and generate a graphical representation based on the data. The controller may determine, using the one or more second sensor devices, at least one of a position or an orientation of one or more portions of the machine; and identify a portion of the graphical representation based on the at least one of the position or the orientation of the one or more portions. The portion may correspond to the material located at the area of interest. The controller may determine, using one or more computational models, a volume of the material based on the portion of the graphical representation.

Systems and methods for compensating dipper swing control. One method includes, with at least one processor, determining a direction of compensation opposite a current swing direction of the dipper and applying the maximum available swing torque in the direction of compensation when an acceleration of the dipper is greater than a predetermined acceleration value. The method can also include determining a current state of the shovel and performing the above steps when the current state of the shovel is a swing-to-truck state or a return-to-tuck state. When the current state of the shovel is a dig-state, the method can include limiting the maximum available swing torque and allowing, with the at least one processor, swing torque to ramp up to the maximum available swing torque over a predetermined period of time when dipper is retracted to a predetermined crowd position.

When an EMV performs an action comprising moving a tool of the EMV through soil or other material, the EMV can measure a current speed of the tool through the material and a current kinematic pressure exerted on the tool by the material. Using the measured current speed and kinematic pressure, the EMV system can use a machine learned model to determine one or more soil parameters of the material. The EMV can then make decisions based on the soil parameters, such as by selecting a tool speed for the EMV based on the determined soil parameters.

System (1-3) for earth moving machinery (100), comprising: a plurality of wear elements (10-15) adapted for coupling with a blade (111) of digging implements (110) of an earth moving machine (100); one or more sensors (20) for measuring forces, each sensor of the one or more sensors (20) being arranged in one wear element of the plurality of wear elements (10-15) or between two wear elements of the plurality of wear elements (10-15); and central control means (50) for processing measurements of the one or more sensors (20) in order to calculate force withstood by the wear elements (10-15).

A shovel includes a traveling body, an upper turning body turnably provided on the traveling body, an attachment including a boom, an arm, and a bucket and attached to the upper turning body, and a processor. The processor is configured to correct a motion of the boom cylinder of the attachment in such a manner as to control a lift of the rear of the traveling body with the front of the traveling body serving as a tipping fulcrum. The processor is configured to correct the motion of the boom cylinder based on a rod pressure and a bottom pressure of the boom cylinder.
