Abstract:
We study alternative paths’ planning problem for an unmanned vehicle. It constitutes a key part of a bigger problem – that of multi-agent path planning, i.e., finding a non-conflicting path set for a coalition of vehicles. We propose a new path-planning technique, which indirectly takes into account vehicle movement dynamics and guarantees feasibly of resulting paths. We also elaborate a number of extensions of the method proposed. We conduct an empirical study of all introduced algorithms by running the large number of experiments simulating nap-of-the-earth flight of a compact multirotor unmanned aerial vehicle in urban environment.
Keywords:unmanned vehicle, multirotor, quadrotor, navigation, intelligent control system, planning, path planning, path finding, alternative paths, k shortest paths, angle-constrained path planning, heuristic search.
