This research aims to demonstrate the control of a robotic arm through a prototyping platform Raspberry Pi, in communication with the internet, demonstrating a simple and inexpensive solution for mechatronics applied to industry. Through a web service administered by the Raspberry Pi, the robotic arm can communicate from anywhere in an industry, using only one device that has a wi-fi connection and is connected in LAN. The Grab proposed in this paper serves only as an example, but any other device may be coupled actuator, thereby facilitating the adaptation of this project for several real situations.
Part of the difficulty in engineering education is to achieve aggregate theoretical knowledge to practice what therefore discourages the student. Trying to alleviate this difficulty, practical problems are created to encourage students to apply their knowledge in different ways; these problems can be computational order, resolved by programs through simulation, or physical, with the realization of models, prototypes, benches or interactive platforms with visual practical approach. From this, it was proposed to students of the Federal University of Pará-Campus Tucuruí through the Electric Power Systems and Mechanics Research Group, in order to apply knowledge arising from multidisciplinary fields of engineering in the construction of a prototype with reused materials and low cost enabling studies and analysis of vibrations in unbalanced motors. This system features an open source prototyping embedded platform Arduino to read values from the sensors used: accelerometers and potentiometers coupled to the engine, aiming to collect values and vary the supply voltage. The results are read by Arduino and computationally processed to be printed on an LCD display. Therefore, the aim of this is to provide an accessible way using simple techniques a prototype linking the theoretical and practical knowledge as the system of the bench that performs vibration analysis in an unbalanced motor interactively, and encourage research and development technologies in the Amazon region.
