On-line Optimization-based Coordination of Multiple Unmanned Vehicles

The objective of this work is to investigate on-line optimization-based coordination strategies for robot teams to efficiently accomplish a mission (eg, reach a set of assigned targets) while avoiding collisions. The multi-robot coordination problem is addressed by solving an on-line receding-horizon mixed-integer program to find some suitable inputs for the vehicles. Simulations results verify the feasibility of our approach.

A Hierarchical Optimization Approach for Cooperative Vehicle Networks

This research presents a control algorithm for the cooperative control of unmanned mobile robots. The algorithm relies on continuously solving an open loop mixed integer linear programming optimization problem. Since the model can become quite complex when the number of robots and the complexity of the environment increase, computational problems can arise. To overcome these problems an approach involving a hierarchical decentralized formulation of the optimization problem is proposed.
