Desarrollo de una interfaz cerebro ordenador para un módulo selector de metal y plástico

Abstract

This project aimed to develop a brain-computer interface for a metal and plastic selection module with the aim of adapting the machinery as an introductory tool for the research field oriented towards the incorporation of work. It started by determining the requirements of the system and detailing the four components that make up the system. Firstly, the input component with the ability to receive brain activity is physically represented by the EMOTIV EPOC + sensory headset. Secondly, the processing component with the attribute of Transformation converts the information from brain activity into a control signal. Thirdly, the output or application component is the metal and plastic selection module controlled by a PLC S7-1200. Finally, an integrating component represented by a graphical user interface was defined in order to communicate the three components in a user-friendly and easy-to-understand application. In the resulting software application, the user can program, train, and validate the brain-computer interface, and then physically and virtually apply the brain-computer interface to the metal selection module. Using functional tests, the time that the device invests in recording and processing brain activity was determined to be 0.314 seconds for each mental command. In addition, a critical time has been defined that the user must decide, corresponding to the route's starting point to the inductive sensor with a value of 7.979 seconds. An integrative system has been developed that can be used in future work as a research tool focusing on work integration, and it is recommended to put the brain-computer interface into practice in a work environment.
