Abstract: A method for depositing piles of material, by a machine, in a work zone of a worksite. The method comprising detecting, by a controller, a first area occupied by a first pile deposited in the work zone, determining, by the controller, an available area in the work zone based on a comparison of the first area with an area of the work zone, determining, by the controller, a remaining number of piles to be deposited in the available area based on the determination of the available area, determining, by the controller, a location for each pile of the remaining number of piles to be deposited in the available area such that each pile of the remaining number of piles are evenly spaced from each other; and generating, by the controller, a machine signal to operate the machine to form the remaining number of piles at the respective determined location.

Abstract: A computer-implemented method of responding to a missed cut during a pass made along a planned cut profile using an implement is provided. The computer-implemented method may include identifying the missed cut based at least partially on an implement position and a target cut point, predicting a performance value of the pass based at least partially on the missed cut and an implement load, and restarting the pass if the performance value is less than a minimum performance threshold and the implement load is less than a minimum load threshold.

Abstract: A system for controlling an operation of a machine is provided. The system includes a controller to communicate with a positioning module disposed on the machine and a sensor module associated with the implement. The controller determines a start location and an end location of the operation, and determines an operating path therebetween. Further, the controller engages the implement with a work surface and moves the machine from the start location. The controller further determines an interrupted location of the machine based on the positioning module and a load acting on the implement. The controller further resumes the operation of the machine from the interrupted location if a first distance between the interrupted location and the start location is greater than a first threshold distance and a second distance between the interrupted location and the end location is greater than a second threshold distance.

Abstract: A method for monitoring a work zone in a worksite is disclosed. The work zone includes an overburden region, a dump region having an incline of positive slope, and an initial pivot point at a junction of the overburden region and the incline. The method includes monitoring, by a controller, an elevation of the work zone based on an elevation data received from one or more sensors. Further, the method comprises detecting, by the controller, a location in the work zone having an elevation lower than an elevation of the initial pivot point based on the elevation data. Furthermore, the method comprises updating, by the controller, the detected location as a new pivot point if the detected location is within a predetermined distance from the initial pivot point.

Abstract: A computer-implemented method for determining a cleanup pass profile for a machine implement is provided. The method may include identifying a pass target extending from a first end to a second end along a work surface, determining a plurality of primitives of a cleanup pass profile extending between the first end and the second end where each primitive may be defined based at least partially on volume constraints, determining a cost value associated with moving the machine implement along the cleanup pass profile based on an optimization cost function, and adjusting the volume constraints associated with one or more of the primitives to minimize the cost value.

Abstract: A control system for controlling an earthmoving machine operating at a worksite is disclosed. The control system includes a receiving unit to receive a first input indicative of a terrain profile of the worksite, a second input indicative of a target terrain profile for the worksite, and a third input indicative of machine characteristics. The control system also includes a mission planning controller to generate an excavation plan based on the first input, the second input, and the third input. The controller controls operation of the machine, based on the generated excavation plan, to obtain an excavated terrain profile. Further, the controller determines whether the excavated terrain profile matches with the target terrain profile, and operates the machine based on inputs indicative of the excavated terrain profile, the second input, the third input, and an extent of match between the excavated terrain profile and the target terrain profile.
