  • Apparatus and method of cell-based path planning for mobile body
    Patent number: 9116523
    Abstract: Disclosed are an apparatus and method of cell-based path planning for a mobile body and a computer-readable recording medium storing the method therein. The method includes receiving a configuration space including a start point and a goal point of the mobile body and position information of obstacles, determining a search order of the obstacles located in the configuration space, performing cell decomposition by repeatedly connecting a vertex of one of the obstacles to a vertex of another obstacle according to the determined search order, and performing cell decomposition by making an extended line from each of non-connected vertices in a direction of dividing vertical angle of each of the non-connected vertices into two.
