Join us in this enlightening episode as we chat with Dr. Gabert about his innovative work in the development of robotic leg prostheses. His pioneering research is set to enhance the mobility and quality of life of millions of individuals with lower-limb amputations.

Dr. Gabert presents a unique robotic leg prosthesis that not only emulates the essential biomechanical functions of the biological knee, ankle, and toe, but also manages to match the weight, size, and battery life of conventional microprocessor-controlled prostheses.

Learn about the impressive torque-sensitive mechanism powering the knee joint and the compliant, underactuated system operating the ankle and toe joints. These components allow for substantial mechanical energy regeneration and closely mimic the key biomechanical functions of the ankle/foot complex during walking.

Dr. Gabert further elaborates on the practical aspects of this prosthesis, discussing how all mechanical and electrical components are enclosed within a compact frame for improved robustness and efficiency.

With clinical tests showing promising results, this innovative prosthetic design holds the potential to significantly improve the real-world mobility of individuals with above-knee amputation.
