Diseño y construcción de un sistema mecánico para la movilización de un robot terrestre con una estructura basada en PLA.

Abstract

The current problematic situation lies in the lack of an efficient solution that integrates 3D printing technology with PLA in the structure of the terrestrial robot, the research focused on the design and development of a mechanical system to facilitate the movement of a robot on land surfaces, adopting a structure based on PLA, for the design different 3D design software were used, such as blender and 3D builder, an image of a virtual robot was used as a reference, which allowed a friendly and minimalist design. After completing the design phase, the structure was printed and assembled. Rigorous tests to identify the need to reinforce areas of the print that, due to their angle, did not have enough material, which reduced their rigidity were carried out. The use of PLA in structures is very versatile because it is a low cost material, that is not toxic, besides being a biodegradable material, in the design of the structure it is necessary to take into account important aspects such as the size of the printing bed because if necessary the model must be cut to join it later without affecting its operation, it can be improved and optimize aspects such as printing times, either by using more printers, increasing the speed or using nozzles of larger diameters.
