Construcción de un prototipo de dispensador automático de fluidos utilizando visión artificial

Abstract

The automatic fluid dispensing prototype uses as hardware a Raspberry Pi module as the main controller and in the software part Open CV programed by Python programming, and it uses a webcam and a Pi camera V2 optical sensors. These cameras are responsible for evaluating frames. They detect either the level of a fluid by means of recognition of the color of a float in a tank or geometric figures such as square contours and circumferences. The entire system is mounted on a metal structure. In addition, it consists of a system of aluminum rails and telescopic rails with a band coupling to the motors and the data extracted by the sensors (optical and ultrasonic), is responsible for the general 3D movement of the dispensing device. For the tests, a car toy that has been conditioned on one of its sides, faces a surface that has a circumference (hole) inside a square. Finally, for visualizing the results, a screen was included, showing the processes of the system. Also, it is possible to control the system through a keyboard, which is in charge of the fluid selection, as well as its quantity.
