Abstract
This work presents the design of a robotic exoskeleton for lower limbs, called Ortholeg 2.0. This prototype has a main goal giving the capacity of walking, sitting, standing, climb up and down stairs to people with total or partial loss of lower limbs movements. The movements of the joints are produced by electrical motors equipped with mechanical reductions to produce smoother movements by reducing its speed and increasing torque. Projected to be lighter and more efficient than previous model, Ortholeg 2.0 was designed considering modern materials of premium quality to its construction, like carbon fiber, aluminum alloys and special polymers. This design processes resulted in a new tubular main frame structure, lighter than previous one, more ergonomic and with a better adjustment for user’s height.
