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) WebFor buffered Voronoi cells as defined in [28], [29], the weighting is w ij= (r i+ r j)kp i p jk; (5) which creates a gap of (r i+ r j) between agent boundaries as a safety radius buffer. Buffered Voronoi Cells guarantee agents with extent will not collide when situated on their boundary, where the buffer is generated around the original ... pullasos ole
