WebJun 1, 2024 · In this paper, we introduce several best-known distributed collision avoidance algorithms and present the Voronoi-based method in detail, which assigns optimal dominance regions for robots using the Voronoi diagram, constrains robot motions within the buffered Voronoi diagram, and follows right-hand rule when deadlock happens … WebThe work builds upon the previously proposed Buffered Voronoi Cell (BVC) approach. We introduce a probabilistic formulation to construct a family of BVCs with specified safety levels, which take into account uncertainty in sensor measurements among the robots. The safety level of a PBVC represents the probability that the area is contained ...
WebOct 15, 2024 · We initially present a greedy capturing strategy for an obstacle-free environment based on the Buffered Voronoi Cell (BVC). For an environment with obstacles, the obstacle-aware BVC (OABVC) is defined as the safe region, which considers the physical radius of each robot, and dynamically weights the Voronoi boundary … WebMar 15, 2024 · Green area shows buffer & problem with buffering into bordering land.

We propose a novel algorithm Deadlock … 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)
WebFeb 26, 2024 · We present a decentralized collision avoidance method for dense environments that is based on buffered Voronoi cells (BVC) and reciprocal velocity obstacles (RVO).
