Abstract

This research project proposes to develop and evaluate a new robotic exoskeleton for lower limbs, anatomical and adjustable with multiaxial joint at the hip, from the Exo-TAO. In this sense, this work will study possible solutions both from a mechanical and ergonomic point of view and develop methods to solve the main existing problems, allowing the user to use the exoskeleton in a safe, comfortable and efficient way.It is intended to carry out a study of the materials, their properties and manufacturing methods, seeking a compromise between characteristics such as resistance, flexibility, freedom of form, mass and costs; besides a rapid prototyping methodology through 3D printing, which together with CAE and CAD analyses, will be used for the development and refinement process of the anatomical structures, the multiaxial hip joint and other parts involved in the project. The new mechanisms developed will act in conjunction with the variable impedance control of the exoskeleton and the developed walker to support walking and promote motor rehabilitation. The new systems and the exoskeleton will be evaluated with healthy volunteers.
