Ortholeg 2.0 ‑ Design of a Transparent Active Orthosis

Abstract

In this work we propose a conceptual solution for performance limitation observed in many lower limb active orthosis. The concept is called transparent orthosis, and its objective is to improve the user walking experience to a more natural level, through the design of a lightweight and ergonomic mechanical structure, while using an autonomous and interactive software architecture. The details of transparency are shown through the design and development of a real transparent orthosis, called Ortholeg 2.0. Some aspects of the presented concept were tested in a previous developed device, the Ortholeg orthosis.
