Abstract: A material management system and method manages and tracks the progress of excavated material transferred through an excavation site by a conveyer system operating in cooperation with an in-pit crusher and conveyer (IPCC). The material management system distinguishes the material dispensed into the IPCC into identified material batches. To track the identified material batches, the material management system records data regarding the conveyer speed and the conveyer distance associated with the IPCC, as well as possible other data regarding the identified material batches. The material management system processes this to track the indentified material batches along the conveyer route.

Abstract: A system for evaluating a position of a target zone relative to a path of a material engaging work implement includes a rotatable implement system, an implement system pose sensor, and a target pose sensor. A controller determines a current pose of a portion of the implement system, determines a first pose of the target zone, determines a plurality of potential paths for moving the work implement to the first pose, and generates an alert command if a kinematic model and desired operating characteristics do not permit movement of the work implement to the first pose.

Abstract: A system for determining an error in a sensed position of a machine includes a position sensing system, a dead reckoning system, and a controller. The controller is configured to determine a difference between a sensed position and a calculated position determined by dead reckoning. The difference is compared to an error threshold defining a maximum acceptable distance between the sensed position of the machine and the calculated position of the machine and an error signal generated if the difference exceeds the error threshold. A pair of offset dead reckoning processes may be used.

Abstract: A method for detecting an obstacle along a known path of a machine can include relating the location of the machine with a map. The map can include a worksite with a known path or known paths that the machine can travel on. The stopping distance of the machine can be determined and based on these identified known path and its characteristics along with a traveling speed and a weight of the machine. A LIDAR region of interest can be determined based on the stopping distance, the position and orientation of the machine, and characteristics of the known path. The machine can include a LIDAR system that can be configured to be oriented with respect to the LIDAR region of interest. A concentrated LIDAR scan can be performed to detect if an obstacle is present within the LIDAR region of interest.

Abstract: A system for preparing a worksite for an additive construction operation includes a positioning system configured to determine positioning signals including topographical characteristics of the worksite. An additive construction plan includes, at least, structure placement data, configured for a desired location for constructing the structure, and toolpath instructions for guiding the implement to construct the structure. A controller is configured to determine a construction zone on the worksite based on the structure placement data and the topographical characteristics of the worksite. The controller is further configured for determining if the construction zone is readied for execution of the toolpath instructions at the construction zone and, if the construction zone is not readied for such execution, identifying one or more impediments to construction at the worksite, within the construction zone, based on the topographical characteristics of the worksite.

Abstract: A control system for a machine, operating on a worksite is associated with an implement, which perform additive construction operations in accordance with a pre-determined implement control plan. The system includes a positioning system, one or more implement control actuators, and a controller. The positioning system is configured to determine positioning signals associated with, at least, a terrain of the worksite and any worksite objects existing thereon. The controller determine an available zone, in which the machine and implement are capable of executing the additive construction operations within the available zone, based on the positioning signals and the pre-determined implement control plan, and determine an operation zone, relative to a desired additive construction site on the worksite, within the available zone, wherein parameters of the operation zone are based, at least in part, on the available zone, the machine configuration, and the pre-determined implement control plan.
