About
Abhra Roy Chowdhury is a robotics researcher whose work spans two compelling frontiers of bioinspired engineering: aquatic locomotion through robotic fish systems and terrestrial mobility through spherical robots. His most significant contributions lie in the mathematical modeling and control of underwater vehicles that mimic carangiform fish propulsion, applying Sir James Lighthill's slender body theory to bridge biological fluid dynamics with practical robotic design. Beginning with foundational design work in 2011, Chowdhury progressively advanced the field through increasingly sophisticated kinematic studies, dynamic modeling, and closed-loop control strategies for body-caudal fin (BCF) mode robotic fish, with his 2015 hydrodynamics study earning 21 citations — his most influential work to date. Simultaneously, he pioneered caterpillar-inspired locomotion for spherical robots, drawing from the rolling behavior of the Pleurotya caterpillar to develop novel gait generation mechanisms controlled through central pattern generators and second-order sliding mode control. His research consistently demonstrates a commitment to translating biological principles into engineered solutions, addressing critical challenges in underwater maneuverability, energy efficiency, and adaptive locomotion in unstructured environments — making his body of work highly relevant to researchers in biomimetics, marine robotics, and autonomous systems.
