Construction vehicles using a teach and repeat system can ascertain boundaries of a task area while working, without knowing a perimeter of the task area before starting the task. The system maps a first path of the vehicle by recording a position of a vehicle moving from a first start position to a first end position. A second path is predicted, based on a shape of the first path, the second path having a second start position and a second end position. A third path is mapped from a third start position to a third end position. Boundaries of the task area are ascertained based on the first path, the first start position, the second start position, the third start position, the third path, the first end position, the second end position, and the third end position.

A mobility platform is configured to execute one or more tasks in a worksite including a first passive landmark and a second passive landmark. The mobility platform may include a chassis, a drive system supporting the chassis, a first laser rangefinder disposed on the chassis at a first location, a second laser rangefinder disposed on the chassis at a second location, and at least one processor. The at least one processor may be configured to determine a position and orientation of the chassis based on a first distance measured by the first laser rangefinder between the first location and a first known landmark position, a second distance measured by the second laser rangefinder between the second location and a second known landmark position, and yaw angle information from at least one of the first and second laser rangefinders.

A method is provided, which includes receiving an indication from a first safety system associated with an isolated operating area that a safety operation is to be performed for the work machine operating in the isolated operating area, determining, in response to receiving the indication, a status of a second safety system associated with the work machine, determining, based on the safety operation and the status of the second safety system associated with the work machine, an adapted safety operation, and controlling operation of the work machine based on the adapted safety operation.

A hauling vehicle including a vehicle body, a distance meter that measures the distance to an obstacle, an in-vehicle controller that controls the vehicle body, and a communication device that communicates with a management controller that manages the vehicle body is provided. In the hauling vehicle, the in-vehicle controller executes primary determination of whether or not the distance meter is in a dirt-presumed state in which dirt of an objective surface of the distance meter is presumed, commands the vehicle body to stop at a current position when determining that the distance meter is in the dirt-presumed state in the primary determination, executes secondary determination of whether or not the distance meter is in the dirt-presumed state after the elapse of a set time from the execution of the primary determination, transmits an alarm to the management controller through the communication device when determining that the distance meter is in the dirt-presumed state in the secondary determination, and commands the vehicle body to resume travelling of the vehicle body when determining that the dirt-presumed state has been eliminated in the secondary determination.

A system for delivering beams to predetermined locations of a work site includes a sorting assembly, a work machine, and a control system. The sorting assembly receives the beams in loose batches and arranges them in a predefined arrangement. The work machine includes an implement having haul elements. The control system receives an instruction to transfer the beams to the predetermined locations and issue a command to move the work machine for operative engagement with the sorting assembly. Further, the control system generates a retrieval command to alter the implement and switch the haul elements to a first condition to retrieve the beams from the sorting assembly. Also, the control system provides a notification to haul the beams to the predetermined locations. The control system generates release commands at the predetermined locations to release at least one beam correspondingly at the predetermined locations in a preset orientation.

Described herein are embodiments of a positioning device for positioning a target in an environment for use by a system in localization in the environment. The positioning device comprises a base, a rod extending along a longitudinal axis of the base, an alignment spike attached to a first end of the rod, and at least three legs connected to the base. The alignment spike comprises a tip for contacting a point on a surface that the positioning device is placed upon. Each of the legs is configured to extend radially from the base and retract radially towards the base.

A mobility platform is configured to execute one or more tasks in a worksite including a first passive landmark and a second passive landmark. The mobility platform may include a chassis, a drive system supporting the chassis, a first laser rangefinder disposed on the chassis at a first location, a second laser rangefinder disposed on the chassis at a second location, and at least one processor. The at least one processor may be configured to determine a position and orientation of the chassis based on a first distance measured by the first laser rangefinder between the first location and a first known landmark position, a second distance measured by the second laser rangefinder between the second location and a second known landmark position, and yaw angle information from at least one of the first and second laser rangefinders.

In many embodiments of the invention, a video monitoring system for construction sites includes one or more stereoscopic cameras configured to capture image data from multiple viewpoints over time, one or more 360-degree cameras configured to capture 360-degree image data, an edge device configured to receive the image data from the stereoscopic cameras and the 360-degree cameras, generate three-dimensional point clouds from the image data, recognize fiducial markers within the image data, identify objects and estimate movement of the objects in the point clouds using a plurality of machine learning models, and generate alerts based on the identified movement of the objects, and one or more client devices configured to receive the alerts from the edge device.

A remote operation system includes: a work machine including an imaging device that captures a video around the work machine, a detection device that detects additional information other than the video, and a first communication device that transmits the video and the additional information; a remote operation room including an operation device, a second communication device that transmits operation information from the operation device to the first communication device and receive the video and the additional information, a display device that displays the video, and an output device that outputs the additional information; and a control device that performs control to transmit or receive essential information and the additional information between the first communication device and the second communication device. The control device controls each of the essential information and the additional information differently based on a communication status between the first communication device and the second communication device.

A method includes providing, from a positioning sensor on a loader vehicle for loading the autonomous load-carrier vehicle, a control signal indicative of a current position of the loader vehicle; determining a point on the pre-set path closest to the current position of the loader vehicle; setting a loading position for the autonomous load-carrier vehicle at a point along the pre-set path based on the point on the pre-set path that is closest to the current position of the loader vehicle; wherein the suitable loading position corresponds to the point closest to the current position of the loader vehicle or is a point in the immediate surroundings of the closest point so as to, when the autonomous load-carrier vehicle stops at the suitable loading position, allow pre-set aligning of a part of the autonomous load-carrier vehicle in relation to the loader vehicle when the loader vehicle is positioned close to the pre-set path; and controlling the autonomous load-carrier vehicle to move along the pre-set path and stop at the suitable loading position.
