The system includes a controller configured to receive data associated with a speed of the at least one traction device of the work machine and determine a slippage condition of the at least one traction device based on the data. The controller is further configured to activate a visual overlay over a virtual image, of the at least one traction device, displayed in a video feed to represent the slippage condition on the remote operator interface. The video feed is a real-time video feed, indicating one or more operations of the work machine, displayed on the remote operator interface.

Abstract: The real time state and stability of a machine are determined and the future stability of the machine is predicted based on different potential machine operations. Sensor inputs including machine speed and acceleration, lift height of a payload, an articulation angle of the machine, a position of the machine, a pitch angle and a roll angle of the machine are used to generate a model for estimating a time series of real time and future values for the degree of stability of the machine by solving a kinematic equation and inputting other machine operational parameters during a timestep of a series of timesteps based at least in part on an estimate of the location of the center of gravity of a first portion of the machine in combination with the payload carried by the machine relative to a predetermined point, and the location of the center of gravity of a second portion of the machine relative to the predetermined point in a subsequent timestep.

Abstract: In a mobile equipment with an articulated front portion having a worktool, a fisheye camera with a wide field of view, containing the front portion, is often mounted in a fixed direction on a rear portion of the mobile equipment. Thus, when the front portion moves (e.g., rotates) relative to the rear portion, a view around the front portion may be compromised due to inherent cropping in fisheye-distortion correction. Digital panning of panoramic video is disclosed that rotates a projection surface, in accordance with movement of the front portion, and generates a projected video on the projection surface, utilizing information that may have otherwise been cropped, to expand the visible area around the worktool. The digital panning in the projected video may mimic an operator turning their head to look down the longitudinal axis of the front portion while using the worktool.

Abstract: A worksite controller can automatically track movement of material on a worksite, based on location information and work event information provided by vehicles on the worksite. The worksite controller can determine and/or use a location of a work tool of a vehicle, rather than coordinates determined by a location sensor mounted elsewhere on the vehicle, to determine when the work tool is located within defined boundaries of work zones associated with material. When the worksite controller determines that the vehicle performed a work event to interact with material while the work tool was within a particular work zone, the worksite controller can automatically update material tracking information associated with the work zone.

Abstract: A payload weight of a load of material carried by an implement of a machine may be estimated taking into account angular acceleration of the payload. A lift cylinder pressure differential and a lift arm angular acceleration may be determined as the implement is raised through a weigh range. An angular acceleration compensation factor may be determined from the lift arm angular acceleration, and a compensated differential pressure may be calculated by multiplying the lift cylinder pressure differential by the angular acceleration compensation factor. The estimated payload weight may then be determined based on the compensated pressure differential and a head end cross-sectional area of the lift cylinder.
