  • Patent number: 10753755
    Abstract: A method controlling movement of an agent moving within an environment represented by a directed graph including vertices located at a border of an unknown portion of the environment, includes: guiding the moving agent via execution of at least one iteration of following successive operations: planning a path towards a destination vertex or border vertex, via a progressively increasing evaluation of a first heuristic of cost; controlling navigation of the agent towards the destination or border vertex returned by the planning; controlling an exploration in the unknown portion if the planning returns a border vertex as the destination. The planning includes, for each calculation of the first cost heuristic for a border vertex, calculation of a second heuristic of risk. The method provides, as the destination, the border vertex with lowest calculated heuristic risk evaluation as soon as the cost exceeds this heuristic risk evaluation before reaching the destination vertex.

    Abstract: A disc opener unit for an agricultural implement has a down pressure adjustment device that automatically adjusts the amount of down pressure applied on a furrowing disc based on strain measurements taken by a strain gauge or load cell. The strain gauge, which may be mounted to an arm that is used to set the position of a depth setting gauge wheel, provides feedback to a processor that in turn controls the amount of hydraulic fluid in a hydraulic cylinder to adjust the down force applied on the disc. The amount of down pressure is therefore adjusted in substantially real-time in response to changes in field conditions, which improves furrow depth consistency and reduces wear on the gauge wheel and its components.
