Aplicação da lei de Fitts na avaliação de um sistema robótico controlado por joystick

Abstract

This work presents the development of robotic arm system, composed of a robotic arm, power supply and control box, in which the user performs the control with joystick movements programmed using an Arduino. In order to illustrate the application of the system, tasks related to Fitts’ Law were performed. For this, a graphical interface was implemented in C#, with a page to fill in information from the researcher and the volunteer and another page with information about the execution of the tasks, providing feedback to the volunteer. Data acquired by the author during tests with the graphical interface was saved to a local SQL database for easing later access. The information collected was analyzed, comparing the different objects and difficulty indexes according to the criteria of Fitts’ Law. Thus, the usability of the system was assessed, together with its wide variety of applications, and can assist students of the Biomedical Engineering course of the Federal University of Uberlândia.
