About

Chase G. Frazelle is a robotics researcher whose work centers on continuum manipulators — flexible, snake-like robotic structures capable of navigating complex, congested environments where traditional rigid-link robots cannot reach. His most influential contribution, "Dynamic Control of Multisection Three-Dimensional Continuum Manipulators Based on Virtual Discrete-Jointed Robot Models" (2020, 74 citations), tackled one of the field's most persistent challenges: achieving reliable, model-based closed-loop control of inherently soft and flexible robotic bodies. Complementing this, his vine-inspired robot exploration work (2018, 56 citations) drew from plant biology to devise novel movement strategies for accessing unstructured environments, demonstrating his creative cross-disciplinary thinking. Frazelle has also made substantial contributions to teleoperation, developing kinematically similar master devices and haptic interfaces purpose-built for extensible continuum robots — work that collectively represents a comprehensive framework for human-robot interaction in this domain. Beyond manipulation, he has extended continuum robotics principles into assistive technology, including robotic furniture for aging-in-place support, and motion planning for continuum-based robotic systems. His exploration of reinforcement learning for autonomous inspection signals a forward-looking research agenda with applications in deep-space environments. Across more than 270 cumulative citations, Frazelle's body of work has meaningfully advanced both the theoretical foundations and practical deployment of continuum robotic systems.
