Abstract
Recent advances in communications, sensing and computation have made possible the development of mobile sensor networks and unmanned vehicles for remote exploration and monitoring tasks. The development of cooperative motion strategies has been fueled by this increasing demand. However, many dynamical models for these autonomous vehicles or sensors remain simple and are not accurate representations of a vehicle where such cooperative motion strategies may be physically implemented. In addition, deployment poses numerous challenges due to the limited computing and communication capabilities of these systems. In this talk, we review the problem of cooperative deployment of autonomous sensor networks subject to various constraints imposed by remaining power supplies, nonholonomic dynamics, and constraints due to external environmental forces. We also discuss how the self/event-triggered principle by which computations and/or communications are employed only when needed can be exploited in these settings.

Short bio:
Sonia Martínez received her Ph.D. degree in Engineering Mathematics from the Universidad Carlos III de Madrid, Spain, in May 2002. Following a year as a Visiting Assistant Professor of Applied Mathematics at the Technical University of Catalonia, Spain, she obtained a Postdoctoral Fulbright Fellowship and held appointments at the Coordinated Science Laboratory of the University of Illinois, Urbana-Champaign during 2004, and at the Center for Control, Dynamical systems and Computation (CCDC) of the University of California, Santa Barbara during 2005. From January 2006 to July 2010, she was an Assistant Professor with the department of Mechanical and Aerospace Engineering (MAE) at the University of California, San Diego (UCSD). Since 2010, she is an Associate Professor at MAE UCSD.

In a broad sense, Dr Martínez' main reseach interests include networked systems, distributed control, nonlinear control, and robotics. In particular, she has focused on the modeling and coordination of robotic sensor networks, the development of distributed optimization algorithms for networked systems such as the power grid, the geometric control of mechanical systems and motion planning. For her work on the control of underactuated mechanical systems she received the Best Student Paper award at the 2002 IEEE Conference on Decision and Control. She was the recipient of a NSF CAREER Award in 2007. For the paper "Motion coordination with Distributed Information," co-authored with Jorge Cortés and Francesco Bullo, she received the 2008 Control Systems Magazine Outstanding Paper Award.
