Projeto de um braço robótico utilizando atuadores pneumáticos e elétricos controlados pelo sistema embarcado Arduino

Abstract

Brazilian industry finds great competition with products manufactured outside the country, which in most cases have superior manufacturing quality and prices that are more competitive with what is produced in Brazil. One of the variables that causes this loss is little or no automated manufacturing parks, leaving them with less efficient processes. Automated processes require a high level of investment and are not feasible for small businesses that want to produce on a large scale. Considering this deficit in the reality of the national industry, the project is a research project and project in the area of industrial automation, as well as related areas, as a starting point for the construction of low cost robotic manipulators. Therefore, the study, analysis and development of an electro-pneumatic robotic mechanical arm with 4 degrees of freedom was carried out to handle loads up to 500g. It combines the use of pneumatic cylinders, pitch motors and servo motors, such as actuators, controlled by a designed joystick. And it has the ATmega2560 microcontroller embedded in the Arduino MEGA R3 system, as the central processing module of the manipulator. Through a firmware developed the operations of control of the arm, having the functions of recording positions and perform movements in the automatic mode. The project has a cost in the range of R$150.00, most of its material comes from scrap and/or removed from the laboratories of UNIPAMPA, and its structure is built with wood place.
