Resumo
To enlarge the active participation of individuals with disabilities in society, some mechanisms
have been developed, such as crustches and wheelchairs. Wheelchairs are widely
used, either temporarily or even permanently, allowing greater mobility and independence
of the individual. However, the same is subject to the physical limitations of the wheels, requiring
regular and hard grouynd to ensure bettermobility. Thus, some studies have suggested
repacing the wheels on the legs, since the same part of the evolutionary process allows
many terrestrial animals and viable movement to the wheels. The mechanisms with legs given
the name of mobile machines. Among the most famous mobile machines are developed
by the dutch phisicist Theo Jansen, called by Strandbeest. This study evaluates the repacement
of the wheels of wheelchairs, for legs, trying to extend its use in less regular land. Also
shown is the pattern of locomotion strcture developed by Jansen and the development of
the Jansen similar structure using multiobjective optimizationmethods in order to ensure a
new optimum configuration, and obtain a prototype proposed to be coupled in a conventional
wheelchair. During the work it is proposed the method of wighted sumwith Pareto, this
method related to onedimensionalyzation objectives. It also presents a brief comparison
with two other methods –Weihted Sumand Pareto Ordination.
