Cadeira retrátil automática

Abstract

This work deals with the development of an automation system of a retractable seat, in order to control access by users to stadiums numbered seats. Currently, there isn’t similar technology in Brazil and the absence of this type of product in the market makes it interesting to develop a prototype. In order to create this prototype, a commercial existent model for stadium chair was purchased and adapted. A mechanical system for the automatic movement of the seat was formulated, as well as a drive and control system, also programed the firmware to Microcontroller, according to the desired logical operation. In order to receive an external identification signal, a simple interface was left to interconnect the modules. After adjustments and prototype validation through testing, it was noted that it is feasible to manufacture this product on large scale.
