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.

The fluid spray system may include at least a first fluid pump configured to supply fluid to a first fluid spray bar and a second fluid pump configured to supply fluid to a second fluid spray bar.

The controller may cause activation of the first fluid pump and the second fluid pump in accordance with the spraying timing.

The processing circuitry can operate the compactor based on the path plan.

Abstract: Non-line of sight (NLOS) remote control for machines is accomplished by a remote-control station with cellular connectivity to run multiple machines remotely. However, NLOS is expensive and may not work in areas with low cell tower coverage. Accordingly, the present disclosure pertains to providing on-machine remote control to operators of machines at a worksite. The on-machine remote control allows one machine to actively control another machine through connectivity between those two machines. For example, a tractor operator may use on-machine remote control to take control of a compactor, such that the compactor may be run using the tractor controls.

Abstract: Systems, methods, and apparatuses can determine weight of a machine using rolling resistance. The machine may be electrified, either all-electrically powered or partially electrically powered. The rolling resistance can be determined based on motor signaling from one or more motor sensors that sense motor characteristics (e.g., drawn current) from one or more electric motors that drive the machine. The weight of the machine can be determined using the determined rolling resistance. Weight information can be output for display on a display and/or for storing in computer-readable storage onboard and/or offboard the machine.
