Projeto de um manipulador robótico de baixo custo

Abstract

Although the use of robotic manipulators is interesting in all sorts of areas, such as inside houses or commercial stores, mainly because it possesses the capacity of moving objects from one point to another, this is not being seen, and all of the low cost manipulators nowadays are mainly being used only for recreational and educative purposes, because of their low reliability and capability to do satisfactory tasks. Taking all of this into consideration, this paper developed a kinematic, structural and dynamic design of a robotic manipulator with a configuration similar to low cost ones, using the same theory and the same concepts that are used for the project of industrial manipulators, where algebraic equations were developed and Matlab functions were implemented. Also, all the components were designed using SolidWorks and a functional prototype was built. From the result obtained from this, an analysis of the designed manipulator was made to identify capabilities, limitations and possible future improvement points. With this, this paper made it clear that the use of robotics theory in the design of even the simplest of low cost manipulators is a powerful tool to identify capabilities and limitations of this kind of robot, and from that find out possible points that could upgrade the whole design to a new level. It also created characteristic project procedures that can be useful in the development of similar robots.
