Aplicação de metodologia de engenharia reversa proposta para documentação de um robô móvel real

Abstract

This work proposes a reverse engineering methodology to create a detailed documentation of an already developed mobile robot. Basic concepts and a brief legislation review are presented as the basis of the applicable methodology proposition, which is an adaptation of Ingle (1994) and Sharples’ (2010) propositions. The practical case analyzed for the reverse engineering process is the analysis of a mobile robot that uses a laser system (LIDAR) to obtain environmental images. The four proposed steps were project reconnaissance, robot analysis, conclusions and documentation. Their detailed description through this work allows the methodology replication. Finally, the generated documentation exposes the results of the application of reverse engineering process in the robot, Nanook. It includes both hardware and software (embedded and user’s interface program) systems. This guarantees that knowledge and understanding acquired during this project are accessible to everyone interested. The comprehension facility is one of the benefits of this process. As a physical investigation would imply in partially disassembling the robot and in spending time in something already done, the needless of these steps are an advantage. Therefore, investments and efforts can focus on generating new results, contributing to the advance of new projects. Aligned with the documentation, hardware schematics were developed using AutoCad®. Hence, there is a safe way (non-invasive) to permit people to understand the robot’s system and to implement improvements in Nanook. Ultimately, the contextualization of the reverse engineering application that derives positive results seeks to contribute to its diffusion as a valid field of study, allowing a final product’s improvement, modification, and documentation, which encourages innovation in the academic and professional environment.
