About
George C. Karras is a prominent robotics and control systems researcher whose work has significantly advanced the fields of autonomous underwater vehicles (AUVs), underwater vehicle manipulator systems (UVMSs), and model predictive control. His research tackles some of the most challenging problems in marine robotics, including trajectory tracking under real-world uncertainties, robust navigation in obstacle-laden environments, and cooperative multi-robot manipulation. Karras's most influential contribution — his 2016 paper on prescribed performance control for underactuated underwater vehicles — has garnered over 210 citations, demonstrating its substantial impact on the robotics community. By innovatively extending prescribed performance control theory to underactuated systems, he provided a mathematically rigorous framework for handling model uncertainties and external disturbances. His subsequent work on nonlinear model predictive control (NMPC) for autonomous navigation and cooperative transportation of multiple UVMSs has further cemented his reputation, accumulating hundreds of additional citations collectively. Beyond marine robotics, Karras has made notable contributions to fault-tolerant control for omnidirectional mobile platforms and vision-based control schemes. His development of self-triggered visual servoing approaches and unsupervised online system identification methods reflects a versatile research portfolio bridging theoretical rigor with practical autonomous systems applications.
