Robô inteligente para uso na agricultura urbana

Abstract

The population growth of the last decades has boosted the territorial increase in severals metropolis, the demand for food and organic food becomes more and more abundant due to such growth. The introduction of systems such as Artificial Intelligence - AI can lead agriculture to a faster and more efficient level of production with quality and sustainability. This work had as objective the development of a robot that performs the steps of the production of vegetables in an automated way. The robot performs tasks such as sowing, checking soil moisture, irrigating it, and eliminating weeds if necessary, with its working tools coupled to an arm that moves by the push of Step motors on the X, Y, and Z axes, counting also with a Raspberry Pi 3 computer, an Arduino Mega 2570 microcontroller and a CNC Shield board. With open source software, the scheduling of tasks to be performed is done on the manufacturer's website. When performing the programming, the coordinates are created for each tool, thus achieving its coupling to perform the work. The robot proved to be very efficient, moving with precision and smoothness, realizing the sequences of planting, irrigation and soil moisture measurement with perfection and accuracy, according to the programming made in the manufacturer's software. The equipment was adapted from a North American model, launched in 2014.
