No. of bitstreams: 1 JobsonFS_DISSERT.pdf: 3147277 bytes, checksum: 9416518f7f32bb71bac0fdf3eb8002f3 (MD5) Previous issue date: 2012-06-08 / The present work shows the development and construction of a robot manipulator with two rotary joints and two degrees of freedom, driven by three-phase induction motors. The positions of the arm and base are made, for comparison, by a fuzzy controller and a PID controller implemented in LabVIEW? programming environment. The robot manipulator moves in an area equivalent to a quarter of a sphere. Experimental results have shown that the fuzzy controller has superior performance to PID controller when tracking single and multiple step trajectories, for the cases of load and no load / O presente trabalho mostra o desenvolvimento e constru??o de um manipulador rob?tico de juntas rotativas com dois graus de liberdade, acionado por motores de indu??o trif?sicos. Os posicionamentos do bra?o e da base s?o realizados, para efeito de compara??o, por um controlador fuzzy e por um controlador PID, implementados no ambiente de programa??o LabVIEW?. O rob? desenvolvido permite movimenta??o numa ?rea espacial equivalente a um quarto de esfera. Resultados experimentais demonstraram que o controlador fuzzy apresenta desempenho superior ao do controlador PID quando o manipulador rob?tico executa trajet?rias dos tipos degrau vari?vel e degrau unit?rio com carga e sem carga
