About

Gregory Bell is a pioneering roboticist whose work has fundamentally shaped the field of visual servoing—the use of computer vision to control robot motion. His landmark 1996 paper, "Relative end-effector control using Cartesian position based visual servoing," with over 620 citations, established a complete design methodology for controlling robots using a single camera mounted on the end-effector. This foundational work introduced the explicit calculation of relative position and orientation (POSE) of target objects, enabling robots to precisely interact with their environment without external sensors. Bell further advanced the field by developing coordinated Cartesian-space LQR controllers that simplified the design of three-dimensional visual servo systems, as demonstrated in his 2002 work. Demonstrating the practical impact of his research, Bell also explored medical applications, co-authoring a 1999 feasibility study on robot-assisted diagnostic ultrasound. With over 730 total citations across his most influential papers, Gregory Bell’s contributions remain essential reading for anyone working at the intersection of robotics, computer vision, and control systems.
