![]() ![]() Our recommendation is to test each component separately. Also, we didn't found the same brass pipes so we ended up printing them. It would be valid to place any nut with some silicone coating to prevent its displacement, or to place Teflon or some similar component. We didn't have all those elements the creator had (in the original project) so we decided to replaced them with M3 screws and an elastic rubber at the end of each screw, so we get the nut fixed in place. The last problem was with the screws, nuts and washers. Due to the precision/configuration and the type of 3D printer used, we to had to sand most of the printed parts to make them fit together, especially the gears. ![]() With the gripper and the rest of the arm we had the same printing problem. We had a problem with the space between the base and the lid, which we filled with EVA (Ethylene Vinyl Acetate) rubber as it's shown in the last picture. As an illustration, we will show some of the parts of the process in the assembly of the robot arm and advice you, so you won't make the same mistakes we did.įirst of all, let's start with the base. Link.Īs for the construction of the arm, we have followed the same steps as the link. In order to unify content, manage document versions, code and so on, we have decided to create a GitHub repository. The main idea, the structure of the robotic arm, the starting code and the tools/utilities can be found in this link. The whole project has been carried out by Clara Rubio Almagro, Laura Sánchez Sánchez and Daniel Bazo Correa, students of Electronic Systems Engineering at the University of Málaga □. This project has arisen for the development of the final practice of the subject of Creative Electronics, a subject belonging to the University of Malaga (UMA), School of Telecommunications. The robotic arm can etiher be operated directly through the Manual Mode or reproduced an Automated programmed movement or even a Party move □□. The main reason for using the Arduino Mega is because of its large number of I/O pins plus extra GND and VCC sockets. This project consists on building and programming a robotic arm able of performing movements manually by joystick control and repeating recorded movements, all controlled by an Arduino Mega. ![]()
