Implementación de un robot cartesiano, para la elaboración de figuras en relieve enfocado a personas con discapacidad visual.

Abstract

A cartesian robot was implemented to the elaboration of relief figures, focoused for people with visual disability, the prototype pretends to be a low cost alternative to one conventional braille printer. The project intents to get a positive social impact in teachers and parents who have visual disability students by having a tool for a personalized instrution. The prototype allows to create braile figures and text in on A4 standart sheets of paper of 120 grams , the elements which make up the project are the Host that is a computer which is loaded with a program that allows to do a treatment of the image and braille symbology, and generate the commands which later will be sent through the USB communication to the robot, an Arduino MEGA 2560 reads the commands that were sent by the Host and transfers all the electrical signals to the acting part of the prototype. The relief generation is elaborated using a punch, which based on a solenoid generates the enough strong in the plunger which to hit the sheet of paper to generate the relief that will conform the braille element. From the tests performed it was establish that the power consume of the implemented prototype is of 55.65 W, that represents a 28% of the power that a conventional printer needs. It was determined that, the braille shapes and writing, elaborated by the prototype conform to the INEN norm 2850 aplyed to devices with similar characteristics. Consequently it can conclude that the implemented prototype can be built as a aid tool for the elaboration od braille didactic material that is similar to commercial equipments. It is recommended to implement a compact modules system with plactic protection of high resistance that reduces the weight, facilitates its transportation and improves its aesthetics.
