[en] ANALYSIS AND DEVELOPMENT OF AN ROBOTIC MANIPULATOR TO STORAGE OF STANDARDIZED CONTAINERS / [pt] ANÁLISE E DESENVOLVIMENTO DE UM MANIPULADOR ROBÓTICO PARA ARMAZENAMENTO DE VOLUMES PADRONIZADOS

JOEL VIEIRA DOS SANTOS JUNIOR 05 November 2002 (has links)
[pt] Grande parte das indústrias e do comércio atacadista e varejista, depara-se com problemas referentes à estocagem de seus produtos em galpões. Visando otimizar as operações de armazenamento e recuperação destes produtos (livros, remédios, CDs, caixas, pallets etc) e melhorar a utilização dos espaços vagos, foi idealizado o desenvolvimento de um protótipo que busca funcionalidade operativa associada a baixo custo.O presente trabalho consiste na construção de um manipulador robótico, controlado através da porta paralela de um microcomputador e composto por guias lineares estruturais, fixadas a um módulo de armazenamento com escaninhos. Para a execução dos movimentos é utilizada a tecnologia de motores de passo, onde dois motores horizontais efetuam os movimentos na coordenada X e um motor vertical, na coordenada Y. Um mecanismo de garras, acionado por motoredutor, foi desenvolvido para a captação dos volumes padronizados (containers). Finalmente, um programa para gerenciamento dos movimentos também foi implementado, com o objetivo de minimizar as operações do manipulador. / [en] A great part of the industry and of the wholesaler and retailer commerce sector, is dealing with some problems related to the storage of their products in sheds. The development of this prototype was initiated in order to improve the products (books, medicines, CDs, boxes, pallets) storage / recovery operations and the use of the vacant spaces. This development also searched to satisfy functionality associated to the low cost. The presented work is based upon the construction of a robotic manipulator. It is controlled by the computer parallel port and composed by structural linear guides that are fixed on a storage module with small partitions, similar to drawers. The movement execution uses the technology of step motors. Two horizontal motors execute the coordinate X movements, and a vertical motor executes the coordinate Y movements. It was developed a end effector mechanism, activated by a motor reducer, in order to capture the standardized containers. It was also implemented a program for the movements management. It looks for the reduction of the manipulator operations. The document s finalization shows and comments the obtained results.
