A Data Driven Approach for Predicting Preferred Ankle Stiffness of a Quasi-Passive Prosthesis

RA-L 2022

Emerging variable-stiffness ankle prostheses can modulate their stiffness to meet differing biomechanical demands. To this end, knowledge of the optimal ankle stiffness is required for each user and activity. One approach is to match the stiffness of prosthesis to the user’s preference, but t

Empirical Characterization of a High-performance Exterior-rotor Type Brushless DC Motor and Drive

IROS 2019poster

Recently, brushless motors with especially high torque densities have been developed for applications in autonomous aerial vehicles (i.e. drones), which usually employ exterior rotortype geometries (ER-BLDC motors). These motors are promising for other applications, such as humanoids and wearable ro…
