The D++ algorithm: Real-Time and collision-free path-planning for mobile robot

This paper proposed an improved algorithm that we call “D++” which can be applied to real-time and collision-free path -planning to solve some problems of common methods at present. D++ algorithm combines the Dijkstra's algorithm with sensor-based method so that D++ algorithm can deal with problems of unknown, large, complex, or dynamic environment, and need only local environmental information initially to find a shortest path. In the later of this article, we demonstrated some examples to show that D++ algorithm is very efficient for path-planning and also very practicable on real mobile robot system.
