About

GR Dunlop’s research is centered on the design, control, and calibration of parallel robotic systems, with a particular emphasis on walking robots and novel kinematic mechanisms. His major contributions include the development of the “restrictedness” concept for hexapod robots, which enables omnidirectional walking and efficient gaits such as the tripod gait—a foundational idea in legged locomotion. He also pioneered calibration methods for parallel topology robots, including the Stewart platform and the more complex Delta robot, advancing precision in robotic manipulation. His work on foot design for large walking Delta robots and geometric modelling for general parallel mechanisms further underscores his impact in robotic kinematics and control. Notably, his novel antenna mount for orbital satellite tracking and marine communications, based on parallel manipulator principles, solved the “keyhole” problem in conventional tracking systems. Dunlop’s most cited paper (18 citations) and his retrofitting of path control to a Unimate 2000B robot demonstrate his practical engineering contributions. His research has influenced both academic robotics and real-world applications in automation and satellite tracking.
