APPARATUS AND METHOD FOR PRECISION CONTROL DURING GRADING OPERATIONS OF A WORK MACHINE
A work machine and method for grading a ground surface may include a frame, a ground-engaging attachment, an attachment coupler coupling the ground-engaging attachment to the frame, an actuator enabling movement of the ground-engaging attachment, an adjustable linkage to adjust a position of the ground-engaging attachment relative to the frame, an adjustable linkage, a sensor, and a controller. The adjustable linkage adjusts a position of the ground-engaging attachment relative to the frame. The adjustable linkage comprises of a first portion and a second portion, an enclosure encircling the second portion wherein the enclosure creates an annular chamber between the enclosure and the second portion. A sensor is coupled to the annular chamber and measures a pressure in the chamber. A controller may be configured to monitor the sensor signal, and perform one or more actions based on the sensor signal.
ON-MACHINE REMOTE CONTROL
Non-line of sight (NLOS) remote control for machines is accomplished by a remote-control station with cellular connectivity to run multiple machines remotely. However, NLOS is expensive and may not work in areas with low cell tower coverage. Accordingly, the present disclosure pertains to providing on-machine remote control to operators of machines at a worksite. The on-machine remote control allows one machine to actively control another machine through connectivity between those two machines. For example, a tractor operator may use on-machine remote control to take control of a compactor, such that the compactor may be run using the tractor controls.
EXCAVATING EARTH FROM A DIG SITE USING AN EXCAVATION VEHICLE
This description provides an autonomous or semi-autonomous excavation vehicle that is capable of navigating through a dig site and carrying an excavation routine using a system of sensors physically mounted to the excavation vehicle. The sensors collect 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 perform an excavation routine by excavating earth from a hole using an excavation tool positioned at a single location within the site. The excavation vehicle is also able to carry out numerous other tasks, such as checking the volume of excavated earth in an excavation tool, navigating the excavation vehicle over a distance while continuously excavating earth from a below surface depth, and preparing a digital terrain model of the site as part of a process for creating the excavation routine.
WORK MACHINE CONTROL SYSTEM, WORK MACHINE, AND METHOD FOR CONTROLLING WORK MACHINE
A distance calculation unit calculates a first distance that is a distance between a first bucket point being a point on a bucket and a target design surface representing a target shape of an excavation target. The distance calculation unit calculates a second distance that is a distance between the target design surface and a second bucket point. The second bucket point is on the bucket on a straight line passing through the first bucket point and is parallel to an edge of the bucket. A tilt control unit compares the first distance and the second distance to calculate a tilt control amount to rotate the bucket around a tilt axis.
REMOTE OPERATION SYSTEM FOR WORK MACHINE
A remote operation system for a work machine includes, at a remote place of the work machine: an image data reception unit that receives a first image in a first imaging range and a second image in a second imaging range at least partially overlapping the first imaging range; and a display control unit that causes a display device to display the first image and the second image including an object whose state changes in an overlapping range between the first imaging range and the second imaging range.
EXCAVATION LEARNING FOR RIGID OBJECTS IN CLUTTER
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.
Method For Controlling Work Machine, Work Machine Control Program, And Work Machine Control System
The method for controlling the work machine includes executing a restraint process of restraining an operation of the work machine based on a detection result of a detector detecting a detection target in a monitoring area around the work machine, performing switching between an enabled state and a disabled state of a function associated with the restraint process, and displaying a display screen including restraint state information indicating whether the function associated with the restraint process is enabled or disabled, on a display device.
Construction Vehicle Safety Mechanism
A safety mechanism for use on a vehicle is provided. The safety mechanism comprises a buffer and a sensor that is configured to send an electrical signal to processing circuitry in the vehicle when the sensor is activated. Sufficient movement of the buffer activates the sensor. A drive line may also be provided with the buffer connected to the drive line. Movement of the buffer may cause rotation of the drive line, and sufficient rotation of the drive line may activate the sensor.
Work Machine
Provided is a work machine capable of eliminating the inconvenience from the operator of the work machine as much as possible while deterring a contact between the work machine and workers, and suppressing a decrease in productivity of the work machine. A work machine 5 includes: an identification information recognition device 41 configured to recognize identification information on a person who enters a predetermined region R around the work machine 5; and a controller 7 configured to control the work machine in accordance with the identification information. When a person enters the predetermined region R under the condition that the work machine 5 is ready for operation, the controller 7 counts the number of times the person enters the predetermined region R as the number of approaches for each person distinguished with the identification information, and controls the work machine 5 based on the counted number of approaches in accordance with the identification information of the person who is in the predetermined region R.
