Desenvolvimento de músculos artificiais através de polímeros eletroativos

Abstract

Researchers are always in search of new technologies. In field of robotics there is no different. ; There is a constant exploration for new materials, mechanisms, actuators and components in general. But there is a challenge that has not been overcome, it is the development of artificial muscles, which is capable of playing the roles and have the same characteristics as natural muscles do. This material will represent a great evolution in robotic movement in the way such as ones made by human or our machines, because it would be possible to replace current components such as electric motors, pneumatics and drive mechanisms. The research is justified in the fact that with the artificial muscles it is be possible to create a new generation of robots, eliminating problems such as friction, wear components, impacts and vibrations. The properties required for an artificial muscle are a quick response to the stimulus, strong force relative to its size, precise movements and constant properties regardless of the size of the muscle, which allows the construction of robots extremely smalls. Due to little of exploration in this field in Brazil it would be expected a high possibility of technological evolution in Brazil. Our research started with a literature review on books, articles, journals and dissertations. After knowing the necessary knowledge for the production of artificial muscles specific equipment and tools became crucial. The actions realized include: design and manufacture of a platform for two-dimensional tests, tests to find out the properties of the polymer used; elaboration of a high voltage circuit that is responsible for triggering muscle and; construction of an artificial muscle. This work has suggested methods to be adopted in the manufacture of artificial muscles.
