About

Craig D. McGray is a pioneering researcher in micro-robotics and self-reconfigurable systems, whose work bridges the gap between microscopic actuation and autonomous robotic collectives. His most celebrated contribution is the development of the first untethered, electrostatic MEMS micro-robot—a 60 μm by 250 μm device featuring a curved steering arm mounted on a scratch drive actuator. This globally controllable micro-robot, detailed in his 2006 paper (338 citations), demonstrated unprecedented maneuverability at the microscale, enabling new possibilities for in-situ sensing and manipulation. Earlier, McGray co-invented the "self-reconfiguring robotic molecule" (241 citations), a modular robotic unit capable of multiple locomotion and manipulation modes. This work laid the foundation for 3D metamorphic robots, where clusters of molecules autonomously reconfigure their shape and function—a concept with polynomial-time planning algorithms. His research has profoundly influenced the fields of distributed robotics, MEMS, and programmable matter, inspiring follow-up work in micro-assembly and swarm robotics. McGray’s achievements showcase a rare combination of nanofabrication ingenuity and systems-level thinking, making him a key figure in the evolution of autonomous micro-robots.
