Projeto da estrutura e da transmissão de um robô para uso em ambiente hospitalar

Abstract

This work presents an innovative way of using robotics in hospital environments, leaving the traditional method and implanting technology in the involvement of health professionals with hospitalized people. The objective of this study was the elaboration of a robot project designed by teachers in the areas of Electrical Engineering and Psychology. Development began with the search for existing models that could contribute to the project. From the classical methodology of the Product Development Process, the designs of the propulsion systems and the structure of a robot were developed. Project requirements along with their target values supported the choices that defined the project. In this way, two traction wheels, driven by independent, but identical transmissions created from three pairs of gears, were chosen to reduce the speed and increase the torque generated by independent electric step motors. For the other support points, silly wheels were used. For general structure, commercial tubular profiles of reduced thickness were selected, together with steel plates, mostly perforated, with the intention of reducing the weight of the assembly, destined to the closing. The structural system will be responsible for behaving all components and characterizing the physiognomy of a robot, it will also be conditioned to a finite element analysis. The specifications and final formats were presented in the form of drawings and tables of materials. Finally, it was concluded in a comparative way the fulfillment of the most important design requirements, highlighting those of greater importance (sic).
