BhattacharyaRobots play an important role in tasks related to surveillance. Teams of mobile robots and autonomous vehicles are often deployed in civil as well as military scenarios for intrusion detection and monitoring purposes. Resilience of the underlying communication network is a key issue in the design of these cyber physical systems. In this talk, I will present several scenarios of adversarial intrusion in teams of autonomous vehicles, and unfold the subtle interplay between communication, control and mobility in networked control systems under adversarial attack. Since secure communication is an essential requirement in mobile distributed multi-agent systems, my talk will focus on formation control problems that arise when a mobile intruder inflicts a jamming attack on the communication network present within a team of autonomous vehicles. Motivated by principles of pursuit and evasion among biological species, I will propose a game-theoretic framework for optimal control and motion planning in autonomous mobile platforms that provides network resilience in the face of adversarial intrusion. The relevant tools are based on ideas from differential games, algebraic graph theory and dynamical systems. I will conclude my talk with some future challenges that need to be addressed in order to resolve issues related to resilience and situational awareness in robotic networks.

 

Sourabh Bhattacharya received his B.Tech in Mechanical Engineering from Indian Institute of Technology, Bombay. He received his MS in Electrical Engineering, MA in Applied Mathematics, and PhD in Electrical and Computer Engineering from the University of Illinois at Urbana-Champaign. After a two year postdoc at Coordinated Science Lab at University of Illinois at Urbana-Champaign he joined Iowa State University as Assistant Professor in the department of Mechanical Engineering. He holds the Henry Black Faculty Fellow in the College of Engineering, and is associated with Virtual Reality and Applications Center at ISU. His research interests are in games and control theory, robotics and compressed sensing.
