A Stair Ascent and Descent Controller for a Powered Ankle Prosthesis
This paper presents a control system for a powered transtibial prosthesis that provides stair ascent and descent capability, as well as ability for user-controlled transitions between walking, standing, stair ascent, and stair descent.
IMU-Based Wrist Rotation Control of a Transradial Myoelectric Prosthesis
This paper describes a control method intended to facilitate improved control of a myoelectric prosthesis containing a wrist rotator.
Variable Cadence Walking and Ground Adaptive Standing With a Powered Ankle Prosthesis
This paper describes a control approach that provides walking and standing functionality for a powered ankle prosthesis, and demonstrates the efficacy of the approach in experiments with a unilateral transtibial amputee subject. Both controllers incorporate a finite-state structure that emulates healthy ankle joint behavior via a series of piecewise passive impedance functions.
Running With a Powered Knee and Ankle Prosthesis
This paper presents a running control architecture for a powered knee and ankle prosthesis that enables a transfemoral amputee to run with a biomechanically appropriate running gait and to intentionally transition between a walking and running gait…
