Design of a lower-limb exoskeleton

Abstract

 In recent years, many mechanisms have been developed to 
help people with reduced mobility, especially for people who 
have injuries that do not allow the mobility of the lower 
body of the human body. In the present work, the properties 
and mechanical movements of a human being, angles of 
movement, extension and flexion of the hip, knee, etc. are 
described. A device has also been designed, using aluminum 
elements to give lightness and robustness to the exoskeleton. 
At the same time, an external casing made of PLA plastic has 
been developed, with all of which it has been tried to make 
a light exoskeleton with a low volume, with the aim that be 
of daily use for people with mobility problems. Five young 
students tested the exoskeleton in laboratory conditions. 
Different parameters have been evaluated as design, range of 
movement and the functionality. A series of characteristics has 
been defined such as the design improvement, functionality 
and navigation, the operating time, speed and data reading 
with myoelectric sensors after trials.
