Abstract: A system and method for marking a boundary while defining an autonomous worksite includes receiving first information indicative of a first maneuvering distance from a side of a machine and activating an indicator. The indicator, representative of the first maneuvering distance, is positioned at the side of the machine to be visible to an operator of the machine. The machine is positioned on a worksite surface along a path to be traversed when executing a work plan. After a control system receives a verification from the operator that the machine may operate outside the worksite area and within an outer boundary defined by the first maneuvering distance, a worksite perimeter is defined to include the path, and a geofence for the machine is determined to substantially overlay the outer boundary.

Abstract: The disclosed technology provides solutions for improving the operation of construction robotics, such as paving machines. In some aspects, the disclosed technology encompasses a paving machine that includes a first surface profiler configured to scan a surface on which a cart travels, a second surface profiler disposed on an actuating tool, a positional sensor configured to generate positional data representing a position of the cart. The paving machine can also include a processor configured for receiving the positional data from the position sensor, receiving surface profile information from the first surface profiler and the second surface profiler, filtering the surface profile information to remove one or more extraneous motion artifacts, and creating a topographic map of the surface based on the positional data and the surface profile information. Computer-implemented methods and machine-readable media are also provided.

Abstract: In a method for determining an area milled by at least one construction machine or at least one mining machine by means of a milling drum (2) by means of working a predetermined area in several milling trajectories by at least one machine (1), determining the length of the milling trajectories along which a milling operation has taken place by evaluating the continuous machine positions, adding up the previously milled partial areas taking into account the length of the milling trajectory and the installed width of the milling drum (2), wherein the partial area currently milled along the milling trajectory is checked, either continuously or subsequently, for overlapping or multiple overlapping with any previously milled partial areas, and any partial areas which overlap are deducted, as overlapping areas, from the added-up previously milled partial areas, the total added-up partial areas milled minus the total overlapping areas established give the milled area.

Abstract: A road finisher comprises a tractor, a material hopper configured to receive material, and a screed mounted to the tractor by towing arms so as to be pivotable around a towing point. The road finisher further comprises a control system comprising a height detection device configured to detect vertical movements of the screed with respect to a height reference and, to generate a height signal based on the detected movements, and an adjusting cylinder connected to the tractor and one of the towing arms and being configured to adjust a height of the towing point relative to the tractor. The control system is configured to compare the height signal to a target value and thereby calculate a control deviation, to limit an adjustment displacement of the adjusting cylinder to a maximum value based on the control deviation, wherein the maximum value is proportional to the control deviation.

Abstract: A memory stores, in advance, target line information indicating an arrangement target of an object to be conveyed and related to a target line denoted by at least one of a curve or a polyline. A controller is configured to: calculate, based on the target line information, target information which is at least one of information about a target coordinate of the object and information about a target direction of the object; calculate, based on the at least one of the coordinate of the object and the direction of the object detected by the detector, detection information which is comparable with the target information; calculate a deviation of the detection information from the target information; and cause a display to display a moving direction of the object which allows the deviation to decrease.

Abstract: A system adjusts an instantaneous turn center for a paving machine having a tow vehicle and a screed assembly towed by the tow vehicle such that no portion of the screed assembly moves backward over freshly laid pavement when the paving machine paves around a curve. The system receives an input from an operator, a sensor, and/or a database. The input includes a distance and a direction from a first vertical axis defined by a traction device of the tow vehicle on a side of the tow vehicle facing the curve, to a second adjusted vertical axis defined by a point at least as far from the first vertical axis as an outer edge of the screed assembly that touches the curve. The system receives the input, and adjusts the instantaneous turn center for the paving machine to coincide with the second adjusted vertical axis.

Abstract: A smart steering control system a paving or texturing machine receives path elements corresponding to current and future positions of the machine. By comparing the current and future elements, an expected completion time is derived for exiting the current position and entering the future position; the smart steering control system synchronizes adjustments of the machine's steerable tracks from the current path to the future path. The smart steering control system functions as a virtual tie rod, preventing damage, enhancing the traction control and pulling power of the machine, and preserving the operating life of its components.

Abstract: A construction machine system comprises a self-propelled construction machine and a total station. The construction machine possesses a machine frame, a drive means and a working means for altering the terrain. A position-determination means determines the position of a reference point on the machine in a first coordinate system independent of the machine. The position-determination means receives satellite signals from a global navigation satellite system (GNSS), wherein in normal operation the machine is controlled using the GNSS such that a reference point on the machine moves along a set target travel path. In a total station control mode, the machine is controlled without the GNSS and only using the total station based on a position of the standpoint and orientation of the total station ascertained in the GNSS control mode, and the position-determination of the construction machine occurs in a second coordinate system based on the total station.
