About

Georges Pagis is a robotics researcher whose work focuses on expanding the usable workspace of parallel robots—a critical challenge in automation and precision machinery. His primary contributions lie in understanding and overcoming Type-2 singularities, configurations where a robot loses control and its dynamic model degenerates. Pagis pioneered methods for safely crossing these singularities rather than avoiding them, effectively enlarging the robot’s operational envelope. His most cited paper, "Enlarging parallel robot workspace through Type-2 singularity crossing" (38 citations), established a foundational approach to this problem. He further advanced the field by analyzing the degeneracy conditions of parallel robot dynamic models (27 citations) and designing controllers that enable stable singularity crossing (10 citations). This work is notable for shifting the paradigm from singularity avoidance to active management, offering practical pathways for more versatile robotic systems. Pagis’s research is particularly relevant for applications requiring large, uninterrupted workspaces, such as machining, assembly, and surgical robotics. His contributions continue to influence the design and control of high-performance parallel manipulators.
