    • The Find-Path Problem in the Plane 

      Nguyen; Van-Duc (1984-02-01)
      This paper presents a fast heuristic algorithm for planning collision-free paths of a moving robot in a cluttered planar workspace. The algorithm is based on describing the free space between the obstacles as a network ...

    • The Synthesis of Force-Closure Grasps 

      Nguyen; Van-Duc (1985-09-01)
      This paper addresses the problem of synthesizing planar grasps that have force closure. A grasp on an object is a force closure grasp if and only if we can exert, through the set of contacts, arbitrary force and moment on ...

    • The Synthesis of Stable Grasps in the Plane 

      Nguyen; Van-Duc (1985-10-01)
      This paper addresses the problem of synthesizing stable grasps on arbitrary planar polygons. Each finger is a virtual spring whose stiffnes and compression can be programmed. The contacts between the finger tips and the ...
