Multi-Agent Motion Planning and Object Transportation under High Level Goals

This paper presents a hybrid control framework for the motion planning of a multi-agent system including N robotic agents and M objects, under high level goals. In particular, we design control protocols that allow the transition of the agents as well as the transportation of the objects by the agents, among predefined regions of interest in the workspace. This allows us to abstract the coupled behavior of the agents and the objects as a finite transition system and to design a high-level multi-agent plan that satisfies the agents' and the objects' specifications, given as temporal logic formulas. Simulation results verify the proposed framework.Comment: To appear in the World Congress of the International Federation of Automatic Control (IFAC), Toulouse, France, July 201

Robust Connectivity Analysis for Multi-Agent Systems

In this report we provide a decentralized robust control approach, which guarantees that connectivity of a multi-agent network is maintained when certain bounded input terms are added to the control strategy. Our main motivation for this framework is to determine abstractions for multi-agent systems under coupled constraints which are further exploited for high level plan generation.Comment: 20 page

Decentralized Abstractions for Feedback Interconnected Multi-Agent Systems

The purpose of this report is to define abstractions for multi-agent systems under coupled constraints. In the proposed decentralized framework, we specify a finite or countable transition system for each agent which only takes into account the discrete positions of its neighbors. The dynamics of the considered systems consist of two components. An appropriate feedback law which guarantees that certain performance requirements (eg. connectivity) are preserved and induces the coupled constraints and additional free inputs which we exploit in order to accomplish high level tasks. In this work we provide sufficient conditions on the space and time discretization of the system which ensure that we can extract a well posed and hence meaningful finite transition system.Comment: 15 page
