Prototipado y construcción mediante impresión en 3D de un brazo inalámbrico para procesos industriales de alto riesgo.

Abstract

The project of wireless arm for industrial processes of high irrigation is a part of a meticulous study of the anthropometric movements of a person; these parameters allow specifying the values of reaches, field of action and turns that the arm must reproduce. This prototype is commanded by a sensory glove equipped with flex sensors placed in each of the fingers; intercommunication and reproduction of movements of the fingers, hand, elbow, and shoulder are driven from the glove placed on the operator and located at a maximum distance of 20 meters considered safe for the worker; all these movements are results of a simulation of Matlab and reproduced by the Arduino boards in their physical connection; wireless communication takes place via Bluetooth with a HC05 master-slave and scope of range tested between 15 to 20 meters of separation man-work center. Each element that makes up the wireless arm is designed, tested and simulated in the CAD program Solidworks. The prototype is printed on material PLA the impression parameters were selected in accordance with the use of elements, at the same time there was realized the assembly of the whole structure and the movement mechanisms were placed (servomotors, cables) for the movement of the wireless arm. The maximum force of lifting tested is 3,35lb. The end result is to safeguard the integrity of the workers as it relates to the elements of occupational health and safety in environments with conditions of handling toxic substances.
