Design and Validation of a Lightweight, Low-Profile Powered Knee Prosthesis with Quasi-Direct Drive Actuation
Ross J. Cortino, Ryan Posh, Emily G. Keller +1
Fully-powered knee prostheses, unlike traditional passive knees, can perform controlled positive work, reducing the need for compensatory behaviors by users during energy-intensive…
A Replay-Constrained Simulation Framework for Personalization of Powered Knee--Ankle Prosthesis Controllers
Duong Le, Ryan Posh, Shihao Cheng +2
Personalization of impedance controllers for powered prosthetic legs is critical to accommodating individual gait biomechanics but remains challenging. Existing methods rely on tim…
Simultaneous Locomotion Mode Classification and Continuous Gait Phase Estimation for Transtibial Prostheses
Ryan Posh, Shenggao Li, Patrick Wensing
Recognizing and identifying human locomotion is a critical step to ensuring fluent control of wearable robots, such as transtibial prostheses. In particular, classifying the intend…
Hybrid Volitional Control of a Robotic Transtibial Prosthesis using a Phase Variable Impedance Controller
Ryan R. Posh, Jonathan A. Tittle, David J. Kelly +2
For robotic transtibial prosthesis control, the global kinematics of the tibia can be used to monitor the progression of the gait cycle and command smooth and continuous actuation.…
