ATHLETIC: Pseudo Anthropometric Exoskeleton with a Semi Passive Actuation System for Countermeasure

Abstract

This paper presents the ongoing ESA project ATHLETIC (AstronauT HeaLtH EnhancemenT Integrated Countermeasure) which aims to develop a new approach of integrated countermeasure device in the shape of an exoskeleton. It focuses primarily on the training of the lower limbs, which are the most heavily affected body parts while astronauts are exposed to microgravity. The ATHLETIC system enables High Intense Resistive Training exercises (HIRT), as well as plyometric exercises such as hopping and jumping. Development and validation shall give an answer to the question if exoskeleton technology is suitable for countermeasure in zero gravity and how such a system performs compared to existing countermeasure devices for zero gravity applications.
