PhD Thesis: Design and control of an exoskeleton for knee.

Advisors: S. Salazar, J. Torres, R. Lozano



The goal is to study, to design and to build biomechanisms (exoskeleton) in order to amplify the force of a human leg. This exoskeleton has medical, civil and military applications, for example it can be used to rehabilitation or load heavy objects.

In the first approach, a human lower limb exoskeleton with two degrees of freedom was built (knee and ankle), based on series elastic actuators that are easy to produce and have more torque by its mechanical structure. They have a position sensor who measures the spring’s deflection to estimate the human force applied to exoskeleton.




Ricardo López was born in Puebla, Mexico, on November 26, 1983. He received the B.S. degree in electronics engineering in 2007 and the M.S. degree in electrical engineering in 2010, from the Benemérita Universidad Autónoma of Puebla, Puebla, currently studying the Ph.D. degree in Automatic Control from the Centro de Investigación y de Estudios Avanzados (CINVESTAV), Mexico City. His current research interests include underwater autonomous vehicles, and exoskeletons.
