About

Hanz Richter is a prominent robotics and control systems researcher whose work sits at the intersection of advanced control theory and assistive technology, with a particular focus on active prosthetic limbs for transfemoral amputees. His research has made significant strides in developing robust, adaptive control strategies that enable prosthetic legs to move naturally, maintain stability under uncertainty, and accommodate real-world environmental forces. Among his most influential contributions is the development of impedance and tracking control frameworks for prosthetic systems, including robust model reference adaptive controllers and composite adaptive impedance controllers, with his 2014 dynamic modeling paper accumulating 78 citations. Richter has also pioneered the integration of energy regeneration into robotic control, proposing novel methodologies for semi-active joints that recover and store energy during motion — work that has drawn considerable interest across the robotics community. His application of nonlinear Kalman filtering techniques to estimate ground reaction forces further demonstrates his commitment to practical, sensor-efficient solutions for real-world prosthetics. With a body of work spanning dynamic modeling, passivity-based control, adaptive systems, and energy-aware robotics, Richter has established himself as a key figure in making next-generation prosthetic technology safer, smarter, and more responsive to the needs of amputees.
