About

R. M. Broughton is a researcher specializing in the control and application of shape memory alloy (SMA) actuators, particularly NiTi (Nickel-Titanium) alloys, for advanced robotic systems. Their key research areas include self-sensing actuation, robust control strategies, and mechanical amplification for SMA-based devices. Broughton’s major contribution is the development of a dual measurement self-sensing technique for NiTi actuators, enabling these components to function simultaneously as both actuators and position sensors. This breakthrough addresses a long-standing challenge in the field—achieving reliable self-sensing under varying temperature and loading conditions—thereby reducing cost and enabling miniaturization in robotics. Their most cited work, "Dual measurement self-sensing technique of NiTi actuators for use in robust control" (2017, 22 citations), demonstrates this innovation’s potential for robust control applications. Additionally, Broughton has explored Bowden tube-based SMA actuators with linear parameter varying models and sliding mode control to overcome strain amplification limitations. With a focused body of work, Broughton’s research advances practical, efficient SMA integration in robotics, offering significant impact for students and researchers interested in smart materials and mechatronics.
