Pareto Optimal Coordination on Roadmaps
نویسندگان
چکیده
Given a collection of robots sharing a common environment, assume that each possesses an individual roadmap for its C-space and a cost function for attaining a goal. Vector-valued (or Pareto) optima for collision-free coordination are by no means unique: in fact, continua of optimal coordinations are possible. However, for cylindrical obstacles (those defined by pairwise interactions), we prove a finite bound on the number of optimal coordinations. For such systems, we present an exact subquadratic algorithm for reducing a coordination scheme to its Pareto optimal representative.

Nonpositive Curvature and Pareto Optimal Coordination of Robots
Given a collection of robots sharing a common environment, assume that each possesses a graph (a 1-d complex also known as a roadmap) approximating its configuration space and, furthermore, that each robot wishes to travel to a goal while optimizing elapsed time. We consider vector-valued (or Pareto) optima for collision-free coordination on the product of these roadmaps with collision-type obs...
متن کاملComputing Pareto Optimal Coordinations on Roadmaps
We consider coordination of multiple robots in a common environment, each robot having its own (distinct) roadmap. Our primary contribution is a classification of and exact algorithm for computing vector-valued — or Pareto — optima for collision-free coordination. We indicate the utility of new geometric techniques from CAT(0) geometry and give an argument that curvature bounds are the key dist...
متن کاملExact Pareto-Optimal Coordination of Two Translating Polygonal Robots on a Cyclic Roadmap
We consider planning optimal collision-free motions of two polygonal robots under translation. Each robot has a reference point that must lie on a given graph, called a roadmap, which is embedded in the plane. The initial and the goal are given for each robot. Rather than impose an a priori cost scalarization for choosing the best combined motion, we consider finding motions whose cost vectors ...
متن کاملAnytime Geometric Motion Planning on Large Dense Roadmaps
For real-world robotic systems, the ability to efficiently obtain motion plans of good quality over a diverse range of problems, is crucial. Large, dense motion-planning roadmaps can typically ensure the existence of such good quality solutions for most problems. This thesis proposes an algorithmic framework for anytime planning on large, dense motion-planning roadmaps. The size of the roadmap ...
متن کاملAnytime Motion Planning on Large Dense Roadmaps with Expensive Edge Evaluations
We propose an algorithmic framework for efficient anytime motion planning on large dense geometric roadmaps, in domains where collision checks and therefore edge evaluations are computationally expensive. A large dense roadmap (graph) can typically ensure the existence of high quality solutions for most motion-planning problems, but the size of the roadmap, particularly in high-dimensional spac...
