  • Publication number: 20120179322
    Abstract: An autonomous navigation system for a tracked or skid-steer vehicle is described. The system includes a path planner (54) that computes a series of waypoint locations specifying a path to follow and vehicle location sensors (82). A tramming controller (60) includes a waypoint controller (62) that computes vehicle speed and yaw rate setpoints based on vehicle location information from the vehicle location sensor and the locations of a plurality of neighbouring waypoints, and a rate controller (64) that generates left and right track speed setpoints from the speed and yaw rate setpoints. A vehicle control interface actuates the vehicle controls in accordance with the left and right track speed setpoints.

  • Publication number: 20120024605
    Abstract: Forming a sequence plan for a machine to travel to a series of specified locations is described. An initial cost table (414) and a pattern of locations (412) is inputted to a Sequential Ordering Problem (SOP) solver (402). The resulting sequence (410) is processed by a motion planner (404) to derive by a motion planning procedure a plan of machine motions through the sequence. A cost table update (408) is performed based on the motion plan, which is then used for another iteration of the SOP solver (402).
