Diseño y construcción de un brazo robotico mediante impresión 3d y Arduino

Abstract

Currently, robotics has evolved unstoppably and with this they have attracted different types of machines or robots to facilitate or automate complex, dangerous or repetitive tasks for humans. That is why software has been created to control these robots from a computer or cell phone. There are different types of robots that can be found in industries or factories, among them we have the Cartesian robot that is characterized by its axes and its main function is the manipulation of objects The polar robot forms a polar coordinate system that allows welding, casting and handling of machines or tools to be carried out, the articulated robot that has at least three joints that allows it to rotate on itself and its main objectives are to weld to paint With spray, the parallel robot is made up of joints in the shape of a prism that is used for a mobile platform from the flight simulations, its level of rotation allows a large amount of movement to make the simulation more complex. Among other robots we have the robotic arms that allow us to do pick and place work, which in Spanish means to pick up and leave objects. Robotic arms are used in large companies to replace and perform the functions of employees, some of these functions can be to repeat a movement thousands of consecutive times without fatigue or to move an object to another side until the stock is full, this Automated processes will allow the partners or owners of the companies to have a greater profit and have their products in a shorter time. The present investigation consists of designing, building a robotic arm with four degrees of freedom, its main function is that of pick and place which means picking up and leaving objects, the control and monitoring process of the robotic arm will be based on an application mobile for cell phones with Android operating system. The prototype design was built by OnShape, which is cloud-based CAD computer-aided design software that allows you to create, model or edit designs from any device, be it a computer, a Tablet or from a cell phone. In addition, we can export the designs in STL, DWG format among others for 3D printing. For the 3D printing of the robotic arm parts we will use the CUBE3 printer, it is a portable printer with a plug and print design that means connect and print.
