Optimized hip-knee-ankle exoskeleton assistance reduces the metabolic cost of walking with worn loads

Journal of NeuroEngineering and Rehabilitation, 2021
Background Load carriage is common in a wide range of professions, but prolonged load carriage is associated with increased fatigue and overuse injuries.

The Effects of Incline Level on Optimized Lower-Limb Exoskeleton Assistance: A Case Series

IEEE Transactions on Neural Systems and Rehabilitation Engineering, 2022
For exoskeletons to be successful in real-world settings, they will need to be effective across a variety of terrains, including on inclines. While some single-joint exoskeletons have assisted incline walking, recent successes in level-ground assistance ...

Phase-Plane Based Model-Free Estimation of Steady-State Metabolic Cost

IEEE Access, 2022
The steady-state metabolic cost has been used to assess the performance of wearable robotic devices. Recently, real-time assessment of this metabolic cost has been employed in an objective function when optimizing robotic parameters for an individual ...

An EMG-Based Objective Function for Human-in-the-Loop Optimization

2023 International Conference on Rehabilitation Robotics (ICORR), 2023
Advancements in wearable robots aim to improve the users' motion, performance, and comfort by optimizing, mainly, energetic cost (EC). However, EC is a noisy measurement with a physiological delayed response that requires long evaluation periods and wearing an uncomfortable mask.

Optimal and Efficient Binary Questioning for Human-in-the-Loop Annotation

CoRR, 2023
Even though data annotation is extremely important for interpretability, research and development of artificial intelligence solutions, most research efforts such as active learning or few-shot learning focus on the sample efficiency problem. This paper studies the neglected complementary problem of getting annotated data given a predictor.

Framework for Personalizing Wearable Devices Using Real-Time Physiological Measures

IEEE Access, 2023
Personalizing wearable robots by incorporating user physiological feedback can improve energy efficiency and comfort. However, many current personalization methods are specific to a particular device and often require reprogramming, making them less ...
