Resumo
Este trabalho apresenta um estudo inicial para avaliar e testar um exoesqueleto passivo para membros superiores em uma linha de produção automotiva. Os testes foram realizados na área da pintura e de montagem durante um dia de produção e nos dois turnos de trabalho com a participação de diferentes setores da empresa. Ao todo, sete operadores participaram dos testes e seis postos de trabalho foram avaliados. Observou-se que em ambas as áreas, o uso do exoesqueleto não apresentou alteração no tempo ciclo das atividades executadas pelos operadores. Nas atividades que exigem sustentação dos membros superiores, o exoesqueleto se mostra mais favorável. Porém, nas atividades nas quais o operador necessita abaixar e elevar os braços diversas vezes ao longo do ciclo de trabalho, o equipamento se mostra desfavorável, pois o operador encontra resistência para abaixar o braço. É necessário aprofundar os estudos com outros modelos de exoesqueleto existentes no mercado e realizar testes com maior tempo de duração.

Abstract
This work presents an initial study to evaluate and test a passive exoskeleton for upper limbs in an automotive production line. The tests were carried out at the painting area and at the assembly area during a day of production compound of two work shifts with the participation of different sectors of the company. A total of seven operators participated in the test and six workstations were evaluated. It was observed that in both areas, the use of the exoskeleton did not change the cycle time of the activities performed by the operators. In activities where the operator needs to maintain the arms raised, the exoskeleton is more favorable. However, in activities where the operator needs to lower and raise the arms several times during the work cycle, the equipment is unfavorable, because the operator finds resistance to lower the arms. It is necessary to deepen the studies with other exoskeleton models available on the market and carry out tests with a longer duration.
