|A Voronoi-Based Framework for Motion Planning and Maintainability Applications|
|Ming C. Linemail@example.com|
Abstract: We present a new approach for motion planning and maintainability studies in complex 3D CAD environments. It automatically computes a collision-free path for a moving object among stationary and completely known obstacles. Our framework uses a combination of analytic, criticality-based and probabilistic techniques to compute the path. It starts with a global strategy that uses an approximate Voronoi diagram of the workspace, computed using graphics hardware. It refines the resulting path with bridges computed by a localized path planner. The resulting system has been used for planning the path of free-flying rigid as well as articulated bodies. Applications of our system include robot motion planning, part removal, and assembly planning. We have implemented a simple planner within this framework and tested it on a number of benchmarks.
