A paving machine may include a frame, a screed, sensor devices, and a control unit. The screed may include a main section, a first extension, and a second extension. The sensor devices may output a first sensor signal corresponding to a position of the first extension and a second sensor signal corresponding to a position of the second extension. The control unit may receive the first and second sensor signals, determine a screed width based on the first and second sensor signals, receive location data corresponding to a location of the paving machine, determine locations of the first and second extensions based on the screed width and the location data, generate a boundary map based on the locations of the first and second extensions, and cause an action to be performed based on the boundary map.

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.

A screed assembly includes an auger, a cylinder, and a vibratory screed. The screed assembly may be included in an undercarriage. The undercarriage may be coupled to a carriage. The carriage may travel along a length of a framework. One or more sensors may be used to determine height information of the screed assembly relative to a surface to be paved. One or more actuators may be used to selectively adjust the height of the screed assembly based on the height information.

An autonomous ground maintenance system comprising a vehicle comprising a chassis supported upon a ground surface by ground support members, a container supported by the chassis, the container defining a discharge outlet operable to disperse treating material held within the container to a target area of the ground surface, a gate adapted to selectively open and close the discharge outlet, a sensor adapted to identify the target area, and an electronic controller supported by the chassis, the controller being in communication with the sensor and the gate. The controller is adapted to position the chassis at a location proximate the target area such that the discharge outlet is capable of delivering the treating material to the target area and energize the gate to open the discharge outlet.

A soil compactor machine can include: a machine frame; at least one cylindrical roller drum rotatably coupled to the machine frame and rotatable about a drum axis oriented generally transverse to a direction of travel of the compactor machine; a plurality of sensors mounting locations on the machine frame for mounting one or more lidar sensors and cameras; and a plurality of brackets, wherein, one of each of the plurality of brackets is positioned at each of the sensor mounting locations for mounting the lidar sensors and the cameras, wherein the bracket at each of the sensor mounting locations has a similar design as the other of the plurality of brackets.

A paving machine includes a mold coupled to a telescopic frame member, by which the mold side-shifts relative to a main frame. A tight clearance between the paving machine and a surface being paved may be achieved by the ability to side-shift the mold. The paving machine may also include a number of vibrator motors. A flow to the vibrator motors may be controllable by a manifold controller. The manifold controller is located on an end of the telescopic frame member. By locating the manifold controller on the telescopic frame member, an operator of the paving machine may both stand on the telescopic frame member to watch the paving mold and adjust the settings of the vibrator controller. This is advantageous in allowing the operator to achieve proper concrete consolidation by visual feedback without leaving the telescopic frame member.

An autonomous articulated soil compactor machine can include: a machine frame; at least one cylindrical roller drum rotatably coupled to the machine frame and rotatable about a drum axis oriented generally transverse to a direction of travel of the compactor machine; a first lidar sensor on a front of the machine; a second lidar sensor on a first side of the machine; and a third lidar sensor on a second side of the machine; wherein the first, second and the third lidar sensors are positioned such that 360 degree lidar coverage is provided around the articulated compactor machine.

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.

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.

A compactor machine can include a machine frame; at least one cylindrical roller drum rotatably coupled to the machine frame and rotatable about a drum axis oriented generally transverse to a direction of travel of the compactor machine; a plurality of cameras mounted to the machine frame so as to provide a 360° bird's eye view of an area around the machine; a display showing the 360° bird's eye view; and a controller; wherein, the controller is configured to determine certain conditions regarding a compacting operation of the compactor machine and the controller overlays a highlight symbol on the 360° bird's eye view on the display notifying a machine operator of the certain conditions.
