A machine for road work can comprise a frame, a plurality of ground engaging units, a plurality of vertically moveable legs, each leg connecting one of the plurality of ground engaging units to the frame, a pair of spatial sensors, such as global navigation satellite system (GNSS) sensors, and a controller configured to, in response to a three-dimensional signal received from each of the spatial sensors, activate at least some of the plurality of vertically moveable legs.

A method and system for estimating surface roughness of a ground for an off-road vehicle to control ground speed comprises detecting motion data of an off-road vehicle traversing a field or work site during a sampling interval. A pitch sensor is adapted to detect pitch data of the off-road vehicle for the sampling interval to obtain a pitch acceleration. A roll sensor is adapted to detect roll data of the off-road vehicle for the sampling interval to obtain a roll acceleration. An electronic data processor or surface roughness index module determines or estimates a surface roughness index based on the detected motion data, pitch data and roll data for the sampling interval. The surface roughness index can be displayed on the graphical display to a user or operator of the vehicle, or applied to control or execute a ground speed setting of the vehicle.

A system for generating a work plan for autonomous operation of a compactor in tandem with an earthmoving machine includes a first controller that receives information pertaining to a work area on which the earthmoving machine is required to perform at least one operation. The system also includes a central controller that receives, from the first controller, information pertaining to the work area on which the earthmoving machine is required to perform the at least one operation and analyzes the work area for virtually segmenting the work area into a plurality of virtual work areas. The central controller also receives, from the first controller, data indicative of a movement of the earthmoving machine through each virtual work area from the plurality of virtual work areas and determines an optimal direction of movement for the compactor based on the data indicative of the movement of the earthmoving machine.

A screeding system for use with a screeding machine during screeding of an uncured concrete surface includes a control and a plurality of sensors. The sensors are disposed at the screeding machine, which has a screed head assembly that is movable over uncured concrete to screed the concrete surface. The sensors include elevation sensors that sense an elevation of the screed head assembly relative to a reference plane established at the concrete area. The control processes data captured by said plurality of sensors while the screeding machine is screeding the uncured concrete surface. Responsive to the data processing of captured data, the control estimates a flatness or levelness or quality of the surface of the concrete being screeded. While the screeding machine is screeding the uncured concrete surface, the control generates an output indicative of the estimated flatness or levelness or quality of the surface.

The disclosed technology relates to an intelligent motion control system that utilizes onboard sensors and processing to guide a surface manipulation machine along a path of travel on a surface, confirm a position of the machine with respect to the surface, and actuate a surface manipulation tool to achieve a desired surface profile or locate a point of interest. The system may include a first and second surface profiler that is configured to scan a surface on which the system travels and a positional sensor configured to generate positional data representing a position of the machine. The processor is configured to generate topography data based on output received from the first surface profiler, generate intermediate data based on output received from the second profiler, compare the intermediate data with the topography data to calculate an offset; and control motion of the system based on the offset.

A method for adhering a tubular body onto a surface that includes smoothing a portion of the surface to create a smoothed segment of the surface and applying a tubular body directly onto the smoothed segment of the surface after the smoothing of the portion of the surface. The surface at the smoothed segment is smoother than the remainder of the surface. The method further includes applying an uncured protectant onto the tubular body while the tubular body is on the smoothed segment of the surface and curing the uncured protectant into a cured protectant while the uncured protectant is on the tubular body on the smoothed segment of the surface. The cured protectant protectively encases and adheres the tubular body to the surface.

Soil compactor including a compaction drum rotatably supported by a compaction roller frame, wherein the compaction drum frame comprises two longitudinal members arranged in a direction longitudinal to the compactor on both sides of the compaction roller and supporting said compaction roller, and, connecting the two longitudinal members together, two cross members arranged in a direction perpendicular to the compactor and along both sides of the compaction roller, wherein the compaction roller frame is connected to a compactor main frame via one of the two cross members, and wherein at least one sight opening is provided within the other of the two cross members.

Method for laying down a pavement consisting of paving material with a road paver screed in which a compaction unit pre-compacts the paving material at cyclical work cycles with a selectable stroke and at a selectable frequency while the pavement is laid down at a selectable paving speed and at least the stroke is automatically adjustable in response to paving parameters.

The disclosure relates to a road paver with a height-adjustable screed for installing a pavement layer and at least one support device for carrying and positioning at least one sensor unit. The support device comprises a center bar, at least one extension bar for the center bar, and at least one attachment unit which detachably attaches the extension bar at one end of the center bar. The center bar and the extension bar are by way of the attachment unit relative to one another—when viewed in the vertical projection plane—at a first mounting angle connectable to one another, and the center bar and the extension bar are by way of the attachment unit connectable to one another—when viewed in the vertical projection plane—at at least one further mounting angle.

A method includes receiving sensor data indicative of a paved surface, and identifying a defect associated with the paved surface based at least in part on the sensor data. The method also includes determining that the defect is of a defect type based on determining that a value associated with the defect is within a value range associated with the defect type. The method further includes generating a command associated with the defect that, when executed by a machine, at least partially remedies the defect. The method also includes providing the command to an electronic device via a network.
