About

A.D.K.H. Pragnathilaka is a robotics researcher whose work centers on assistive and rehabilitative exoskeleton technologies, with a particular focus on lower-limb biomechanics and human–machine interaction. His most notable contribution is the development of the C-JAE, a three-degree-of-freedom robotic ankle exoskeleton designed with compatible joint axes to mimic natural triplanar motion. This device uniquely integrates externally powered plantarflexion-dorsiflexion and inversion-eversion, while allowing passive internal-external rotation, enhancing both comfort and biomechanical fidelity. The C-JAE paper has garnered 12 citations, reflecting its relevance in the growing field of wearable robotics for gait rehabilitation and human augmentation. Pragnathilaka’s work addresses critical challenges in exoskeleton design—namely, joint misalignment and range of motion—offering a more anatomically compatible solution that could improve clinical outcomes for individuals with ankle impairments. His research sits at the intersection of mechanical engineering, control systems, and rehabilitation science, and his contributions are particularly valuable for students and researchers exploring the next generation of lightweight, adaptive exoskeletal devices.
