About

Ryan Coulter is a rising figure in soft robotics, specializing in the design and control of novel artificial muscles and compliant manipulators. His research focuses on creating lightweight, low-cost robotic systems that can safely interact with humans and delicate environments. Coulter’s major contributions include the development of a twisted string actuator-driven soft robotic manipulator, which demonstrated how simple, tendon-like mechanisms can enable dexterous, compliant motion without bulky motors. This work, published in 2021 and garnering 12 citations, has been influential in advancing accessible soft robotic hardware. He also pioneered the helically wrapped supercoiled polymer (HW-SCP) artificial muscle, a significant innovation that overcomes the strain limitations of conventional supercoiled polymers. By modeling and characterizing this new actuator design, Coulter showed how to achieve both high force and large contractions—a critical step toward practical robotic muscles. His 2020 paper on this topic has earned 9 citations, reflecting its impact on the field. Through these achievements, Coulter is helping to bridge the gap between soft actuator research and real-world robotic applications, making him a promising contributor to the future of safe, adaptive robotics.
