IEEE ROBOTICS AND AUTOMATION LETTERS, 7(2), 2549–2556.

By: W. Liu  n, J. Zhong *, R. Wu *, B. Fylstra n, J. Si* & H. Huang n 

Contributors: W. Liu n, J. Zhong *, R. Wu *, B. Fylstra n, J. Si* & H. Huang n 

author keywords: Learning from demonstration; reinforcement learning; wearable robotics
TL;DR: This study proposes a new inverse approach from observed human-robot walking behavior to infer a human- robot collective performance objective represented in a quadratic form and introduces a new tool to the field of wearable lower limb robots. (via Semantic Scholar)

2022 journal article

Is there a trade-off between economy and task goal variability in transfemoral amputee gait?

JOURNAL OF NEUROENGINEERING AND REHABILITATION, 19(1).

By: I. Lee n, B. Fylstra n, M. Liu n, T. Lenzi * & H. Huang n 

Contributors: I. Lee n, B. Fylstra n, M. Liu n, T. Lenzi * & H. Huang n 

author keywords: Mechanical energy; Goal equivalent manifold; Transfemoral amputee; Energy recovery rate; Walking
MeSH headings : Amputees; Artificial Limbs; Gait / physiology; Goals; Humans; Walking / physiology
TL;DR: This study investigated how unilateral transfemoral amputees regulate step and stride variability based on the task to achieve energy economy and found a negative relationship between energy recovery rate and non-goal-equivalent variability. (via Semantic Scholar)
