Evaluating Computational Approaches to Metabolic Cost Estimation in Gait Assistance with a Passive Exosuit*

Vahid Firouzi, Oskar von Stryk, André Seyfarth, Seungmoon Song, Maziar Ahmad Sharbafi
IROS 2025

Lower limb exoskeletons and exosuits have shown promise in augmenting human physical capabilities, with applications ranging from rehabilitation to performance enhancement. Accurate evaluation of their impact on metabolic energy expenditure is crucial for optimizing design and control strategies. Wh

Exploring the Virtual Pivot Point in Unilateral Transfemoral Amputee Locomotion: Implications for Prosthetic Development

Omid Mohseni, Serajeddin Ebrahimian, Vahid Firouzi, Morteza Khosrotabar, Mario Kupnik, Maziar Ahmad Sharbafi +1
IROS 2025

The virtual pivot point (VPP), a theoretical convergence point of ground reaction forces during gait, has gained attention for its potential to uncover underlying locomotor control strategies. Here, we present the first investigation of VPP in individuals with unilateral above-knee amputation, using

Morphological Computation in Robotic Hopping: The Role of Monoarticular and Biarticular Muscle Configurations

Marc Murcia, Omid Mohseni, André Seyfarth, Gregory S. Sawicki, Maziar Ahmad Sharbafi
IROS 2025

Human locomotion exhibits extraordinary adaptability and robustness, yet the mechanisms by which lower limbs adjust to sudden environmental disruptions remain poorly understood. To address this, we employed the bioinspired human-sized EPA-Hopper II robot to examine how lower-limb joints recover from

Adjustable Compliance and Force Feedback as Key Elements for Stable and Efficient Hopping

Rustam Galljamov, Arjang Ahmadi, Omid Mohseni, André Seyfarth, Philipp Beckerle, Maziar Ahmad Sharbafi
RA-L 2021

Achieving efficient and human-like hopping motions with consistent consecutive patterns requires proper mechanical design and control. In this regard, we introduce a new bioinspired design and control approach comprised of a hybrid actuation system and force-based compliance control. Combining an el
