Embodiments of a learning-based excavation planning method are disclosed for excavating rigid objects in clutter, which is challenging due to high variance of geometric and physical properties of objects, and large resistive force during the excavation. A convolutional neural network is utilized to predict a probability of excavation success. Embodiments of a sampling-based optimization method are disclosed for planning high-quality excavation trajectories by leveraging the learned prediction model. To reduce simulation-to-real gap for excavation learning, voxel-based representations of an excavation scene are used. Excavation experiments were performed in both simulation and real world to evaluate the learning-based excavation planners. Experimental results show that embodiments of the disclosed method may plan high-quality excavations for rigid objects in clutter and outperform baseline methods by large margins.

An excavator attachment is attached to a rotating platform of an excavator. A display unit visually displays a predicted stability indicating stability of the posture of the excavator after the excavator is manipulated.

Drive control of an actuator is performed by using an operation amount versus control value map so that the actuator can be driven at a speed corresponding to an operation amount of an operation member, even if there is difference in load conditions or the like or deterioration over time. An operation amount control unit that determines an operation amount to be input into the operation amount versus control value map is provided. Said operation amount control unit is provided with a speed requirement computing unit that determines a speed requirement from an operation detected value of the operation member, a main map for determining an operation amount from a speed requirement, a sub-map for correcting an operation amount based on influencing factors that have an influence on drive speed of the actuator, and main map updating means for updating main maps, and sub-map updating means for updating sub-maps so as to decrease the speed difference between actual speed and speed requirement of the actuator, and is configured to determine an operation amount by using updated main map and sub-map.

A site-aware controller and various sensors determine if objects are located within a safety dome surrounding a machine such as a construction vehicle. The site-aware controller compares data from the various sensors to determine if the machine or independently moveable implements located on the machine are capable of impacting objects within the safety dome and/or travel of the machine into restricted areas. Detection of objects within the safety dome can trigger alerts (e.g., visual and/or audible) to an operator of the machine of a particular situation. Detection of objects within the safety dome can also prevent further movement of the machine or independently moveable implements located on the machine to prevent impacting the objects. The system can also prevent movement of the machine into restricted areas.

The invention relates to civil engineering underground equipment comprising at least one work element for ground work, at least two actuation units, at least one measuring device for determining at least one current actuation parameter for each actuation unit, and a controller which is designed for controlling the actuation units, wherein the controller is connected to the measuring devices and, in order to prevent a tipping of the civil engineering underground equipment, is designed to limit a further actuation of the actuation unit or to display to an operator that the limit actuation parameter has been reached and/or the limit actuation parameter, on the basis of previously calculated limit actuation parameters for the actuation units which define exactly one permissible operating range, when a limit actuation parameter of at least one actuation unit is reached. It is intended for at least two different individual operating ranges to be stored in the controller, wherein each individual operating range comprises a different set of limit actuation parameters for the actuation units, and for the controller to be able to determine a combined permissible operating range.

A device may receive sensing data that is produced by an environment associated with a fiber optic cable. Based on the sensing data, the device may determine a sensing profile, which indicates a measure of vibration as a function of distance along the fiber optic cable and as a function of time. The device may receive new sensing data produced by the environment. The device may determine that the new sensing data satisfies a vibration deviation criteria, relative to the sensing profile, for a duration threshold. By satisfying the vibration deviation criteria for the duration threshold, the new sensing data may indicate that the environment includes an activity associated with an increased likelihood of damage to the fiber optic cable relative to the sensing data. The device may perform one or more actions based on the new sensing data satisfying the vibration deviation criteria for the duration threshold.

A control method for a work machine, includes: detecting a posture of a working unit driven by a hydraulic cylinder in a movable range; determining whether the working unit at a stop position of the movable range has started moving based on an operation of the working unit; setting a deceleration section including an end position of the movable range and a deceleration ratio of the working unit in the deceleration section, based on the posture of the working unit in a stopped state at the stop position, and a threshold determined in advance; and outputting a command signal to a control valve, which is capable of adjusting an amount of a working oil supplied to the hydraulic cylinder, such that the working unit moves from the stop position to the end position based on the deceleration section and the deceleration ratio.

A control system for an implement associated with a machine, the machine operating on a work surface lying in a surface plane, is disclosed.

The system may further include an orientation leveling system which includes an orientation sensor, one or more plate actuators for altering orientation of the base plate, and an electronic controller. The electronic controller is configured to determine if the plate plane is substantially parallel with the surface plane and actuate the one or more actuators to alter orientation of the base plate to position the base plate such that the plate plane is substantially parallel with the surface plane, if the plate plane is not substantially parallel with the surface plane.

A system for setting a dump height of a work implement includes a linkage assembly and a linkage position sensor. In one embodiment, a controller stores an identifying code corresponding to the dump body, stores a desired dump height, associates the desired dump height with the identifying code, and subsequently receives the identifying code. In another embodiment, the controller stores a plurality of linkage positions corresponding to a plurality of desired dump heights, receives data indicative of a minimum lifting height of the dump body, and determines a desired dump height at which the linkage assembly is to be positioned. In both embodiments, the controller generates a command to position the linkage assembly at the desired dump height and generates a command to dump material within the material engaging work implement into the dump body.
