About

Gregory J. Hamlin is a pioneering roboticist whose work has fundamentally shaped the field of modular and reconfigurable parallel robotics. His most influential contribution is the development of the **TETROBOT system**, a highly innovative, actuated robotic structure that can be disassembled and reassembled into countless configurations while retaining the same hardware and software architecture. This breakthrough, detailed in his seminal 1997 paper (103 citations), addressed critical needs in demanding domains like space exploration, undersea operations, mining, and construction. Hamlin’s key innovations include the **concentric multilink spherical (CMS) joint**, a novel mechanism allowing multiple struts to rotate about a single point, replacing traditional ball joints and enabling hyper-redundant parallel mechanisms. His experimental work, including prototypes with up to 18 nodes and 48 links (71 citations), demonstrated the system’s remarkable versatility and control. With over 360 total citations across his core publications, Hamlin’s research remains foundational for engineers designing adaptable, robust robotic systems for extreme environments.
