Buffered voronoi
WebThis paper introduces a distributed multi-robot collision avoidance algorithm based on the concept of Buffered Voronoi Cells (BVC). We propose a novel algorithm for avoiding deadlocks consisting of three stages: deadlock prediction, deadlock recovery, and deadlock recovery success prediction. Simple heuristics (such as the right-hand rule) are often …

WebDescription. [V,r] = voronoiDiagram (DT) returns the Voronoi vertices V and the Voronoi regions r of the points in a Delaunay triangulation. Each region in r represents the points surrounding a triangulation vertex that are closer to that vertex than any other vertex in the triangulation. The collection of Voronoi regions make up a Voronoi diagram.

WebFor a given buffered Voronoi decomposition of the space, any point p ∈ Rn can be inside of at most one of the buffered Voronoi cells. We use this property in order to avoid robot-to-robot collisions. Using the hyperspaces Sj i we can reformulate V i as follows: V i = j=i Sj i, where S j i = p: αj i ·p−β j i ≤ 0. (4)
