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.

There is provided a technology capable of improving work efficiency of a work machine that is remotely operated by an operator through a remote operation apparatus. If a first condition is satisfied, that is, if an engine stop instruction for a work machine 40 is made through a remote input interface 21 of the remote operation apparatus 20, operation of an engine 460 is stopped in principle, but the operation of the engine 460 is exceptionally not stopped. Specifically, when an operator does not exist at a specified position at the time of operating a remote operation mechanism 211 in the remote operation apparatus 20, the operation of the engine 460 is stopped. On the other hand, when the operator exists at the specified position, the operation of the engine 460 is continued without being stopped even if an engine operation instruction is made.

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.

A computer system for preventing collisions between a first and a second vehicle operating at a work site is described, along with a corresponding computer implemented method and a computer program product.

In one aspect, a method for shared access of a machine for operator training, the machine including a traction device and an implement, includes receiving an authorization from an access device to share access to the machine, and entering a shared control state based on at least the authorization received from the access device. The method also includes receiving commands from a remote operation device during the shared control state and operating at least one of the traction device or the implement of the machine based on at least the commands from the remote operation device while an operator is present in the machine.

A first control unit outputs, to a work machine including work equipment, a first control signal of moving the work equipment to a position above a loading point before a transport vehicle including a dump body reaches the loading point. A transmission unit transmits, to the transport vehicle, an accessing instruction to travel the transport vehicle such that the dump body is located at the loading point. A second control unit outputs a second control signal of controlling the work machine or the transport vehicle such that a deviation between a waiting position of the work equipment and a position of the dump body when the transport vehicle arrives at the loading point based on the accessing instruction becomes small. The waiting position is a position of the work equipment holding an excavation object and waiting based on the first control signal.

A controller may configure the machine to operate in a plurality of modes including a manned control mode, a remote control mode, and an autonomous control mode. The controller may receive a request to cause the machine to perform an action; and determine a requested mode of operation of the machine associated with the request. The requested mode of operation may be one of the plurality of modes. The controller may selectively deny the request or enable the machine to perform the action based on a priority assigned to a current mode of operation of the machine and a priority assigned to the requested mode of operation.

In an aspect, the present disclosure describes a method comprising using at least one robot to fully autonomously position and assemble at least one solar module and its supporting structure at a sensed geolocation without aid from a user.

The invention relates to a demolition robot (1), comprising a cable (12) intended to be connected to an electric network to power a motor (21), a pump (22) that is powered by the electric motor for generating a hydraulic flow to consumers (13), wherein the motor (21) is activable at varying thermal load values (PT), depending on the current consumer's (13) need for hydraulic power, a control unit (24) arranged to receive information about the thermal load (PT) on the motor, to determine a partial thermal damage value (SL, SM, SH) at various thermal loads (PT) on the motor. To minimize the risk of thermal damage to the motor, the control unit (24) is adapted to compare said partial thermal damage values (SL, SM, SH) with a normative partial thermal damage (A) and is adapted to limit the thermal load (PT) on the motor (21) to a maximum allowable thermal load value (PTmax), if the partial thermal damage value (SL, SM, SH) exceeds the normative partial thermal damage (A) at a predetermined value (A′).

A point generating unit of a mobile terminal generates teaching point information associating a teaching position that teaches the work machine a position of the attachment in a series of movements to be performed by the work machine with orientation information indicating a target orientation at the teaching position, based on a slewing angle of an upper slewing body and on orientation information on the attachment. A point changing unit changes the generated teaching point information. When the teaching point information is changed, an instruction generating unit of the work machine generates an automatic operation instruction for automatically operating a slewing device and the attachment, based on the changed teaching point information. An operation control unit of the work machine automatically operates the slewing device and the attachment, based on the automatic operation instruction.
