Abstract

Current control applications necessitate in many cases the consideration of systems with multiple interconnected components. These components/agents may need to fulfill high level tasks at a discrete planning layer and also coupled constraints at the continuous control layer. Towards this end, the need for combined decentralized control at the continuous layer and planning at the discrete layer becomes apparent. While there are approaches that handle the problem in a top-down centralized manner, decentralized bottom up approaches have not been pursued to the same extent. We present here some of our initial results for the problem of combined, hybrid control and task planning from high level specifications for multi-agent systems in a bottom up manner. In the first part, we present some initial results on extending the necessary notion of abstractions to multi-agent systems in a distributed fashion. We then consider a set up where agents are assigned individual tasks in the form of Linear Temporal Logic (LTL) formulas and derive local task planning strategies for each agent. The results are supported by simulations and experiments in different robotic testbeds.
