About
John Fletcher is a leading researcher in robotics and precision mechatronics, with a primary focus on developing high-performance sensing and actuation systems for modular robotic joints. His most impactful work introduces a novel high-resolution optical encoder that employs an axially stacked coded disk, ingeniously designed using graph theory-based Hamiltonian cycles. This breakthrough enables absolute position sensing with exceptional resolution while maintaining a remarkably compact form factor—a critical advancement for lightweight, modular robotic arms. The 2018 paper detailing this innovation has garnered 24 citations, reflecting its significance in addressing the longstanding trade-off between encoder resolution and physical size in robotics. Fletcher’s contributions are particularly notable for their rigorous integration of physical modeling with experimental validation, bridging theoretical design principles and real-world application. His work directly supports the development of more dexterous, space-efficient robots for manufacturing, medical assistance, and collaborative automation. By solving a fundamental challenge in joint-level sensing, Fletcher has provided a foundational technology that enables engineers to build smaller, more capable robotic systems without sacrificing precision or reliability.
