Biography

Hyongju Park was born in Seoul, South Korea. He received the B.S. and M.S. degrees in mechanical engineering from Korea University, Seoul, South Korea, in 2007 and 2009, respectively. He is currently working toward his Ph.D. degree in mechanical science and engineering at the University of Illinois at Urbana-Champaign. His research interests include coordination control of robotic networks, distributed sensor networks, and fault-tolerant multi-robot systems.

Research

Hyongju Park's research goal is designing distributed coordination algorithms for multi-robot systems (i.e., multi-agent systems) that are resilient to possible robot failures. Those failures include random failures experienced by individual robots, as well as the possibility of malicious behavior by some of the robots. Compared to other problems of designing distributed coordination strategies for multi-robot systems, his problem has its own difficulty due to faulty robots being indistinguishable members of the multi-robot system.

Thus, Park's problem is different from multi-robot game theory problems where each robot computes the best strategy knowing that other robots will do the same where the typical objectives of these studies are to find the, e.g., Nash equilibrium. Also, his problem is much different from the robust control problems where the main concern is robust design of a control system that is insensitive to modeling errors/uncertainty.
