Solving Coverage Problems with Embedded Graph Grammars
(Georgia Institute of Technology, 2007-04)
We show how Embedded Graph Grammars (EGGs) are used
to specify local interaction rules between mobile robots in a natural manner. This formalism allows us to treat local network topologies, geometric
transition conditions, ...
From Empirical Data to Multi-Modal Control Procedures
(Georgia Institute of Technology, 2005)
In this paper we study the problem of generating control programs, i.e. strings of symbolic descriptions of control-interrupt pairs (or modes) from input-output data. In particular, we take the point of view that such ...
Optimization of Multi-Agent Motion Programs with Applications to Robotic Marionettes
(Georgia Institute of Technology, 2009-04)
In this paper, we consider the problem of generating optimized, executable control code from high-level, symbolic specifications.
In particular, we construct symbolic control programs using strings from
a motion description ...
Conflict Resolution for Autonomous Vehicles: A Case Study in Hierarchical Control Design
(Georgia Institute of Technology, 2002-09)
In this paper we consider the problem of conflict avoidance for autonomous systems using a hierarchical control strategy that we establish using the notion of predicate consistent abstractions. We apply our proposed ...
A Software Tool for Hybrid Control
(Georgia Institute of Technology, 2008-03)
In this article, we introduce the MODEbox tool for automatically producing hybrid, multimodal control programs from data. In particular, given an I/O string, four distinct operational units are introduced. The application ...
Executive Decision Support: Single-Agent Control of Multiple UAVs
(Georgia Institute of Technology, 2009-05)
One challenge facing coordination and deployment of unmanned aerial vehicles (UAVs) today is the amount of human involvement needed to carry out a successful mission. Currently, control and coordination of UAVs typically ...
Controllability of Multi-Agent Systems from a Graph-Theoretic Perspective
(Georgia Institute of Technology, 2009-02)
In this work, we consider the controlled agreement problem for multi-agent networks,
where a collection of agents take on leader roles while the remaining agents execute local,
consensus-like protocols. Our aim is to ...
Data-Driven Generation of Low-Complexity Control Programs
(Georgia Institute of Technology, 2004)
In this paper we study the problem of generating control programs, i.e.
strings of symbolic descriptions of control-interrupt pairs (or modes) from
input-output data. In particular, we take the point of view that such ...
Feedback Can Reduce the Specification Complexity of Motor Programs
(Georgia Institute of Technology, 2003-02)
In this paper, we show that when it is possible to use
feedback in the specification of "motor programs," the length of the
descriptions of the instruction sequences for carrying out a given
task can be reduced by a ...
