  • Publication number: 20200332479
    Abstract: A method includes receiving information indicative of a first worksite plan, determining a travel path extending along a work surface, causing a mobile machine to traverse the travel path, and receiving first sensor information associated with the work surface from a sensor of the mobile machine. The method also includes generating a second worksite plan based at least partly on the first sensor information, and providing instructions to a slave machine which, when executed by a controller of the slave machine, cause the controller of the slave machine to control the slave machine to perform at least part of the second worksite plan. The method further includes receiving second sensor information determined by the sensor of the mobile machine, and generating at least one of a safety metric and an accuracy metric based at least partly on the second sensor information.

  • Publication number: 20200319646
    Abstract: A control system for an autonomous vehicle is disclosed. The control system may receive information that identifies distances, measured by a sensor of the autonomous vehicle, to different points of a roadway. The control system may generate a representation of a curve based on the information that identifies the distances. The representation of the curve may include a series of points that represent a curvature of the roadway. The control system may identify a point, of the series of points, that satisfies a condition based on the representation of the curve. The control system may store, in the memory, an indication that the point is a center point of the roadway.
