Montagem e teste de um robô para uso em lavoura cafeeira

Abstract

With automation evolution, and also the populational growth, na increasing challenge for the food producers in the global scale and also for those who supply their work equipament is the technology development, in order to allow bigger productivity. Together with that, a new important direction being taken is the use of clean energy sources. In that context, this monography presents the assembly and test work developed for a robot to be used in the future on coffee crops. The robot moves using wheels, propelled two by two, by na eletric motor on each side. On this project were made the physical structure assembly, as well as the conception and assembly of the electro-electronic systems, both power and command-control. Both motors are driven individually, through OSMC boards, devices with a driver chip on it properlly designed to control high performance DC motors. Each motor has its own control board (OSMC), and the command is applied on them both using only one Arduino microprocessor. In order for the robot to perform its movement safely, both for itself and for any person or obstacle it may find on its way, it was instrumented with variable reading ultrasonic sensors, this way, within the sensor operating radius (up to 4m), the assembly can be configured to operate on various distances, according to the application and operation speed.
