A fully 3D-printed, two-axis robotic arm that utilizes SCARA topology to draw on an 8.5” x 11” sheet of paper. We implemented a system that processes G-code commands as input, enabling precise movements of up to 180 degrees at a speed of 4 inches per second. With a writing utensil and a sheet of paper, the robotic arm can draw any design. The system must meet the engineering requirements such as drawing at a speed of 4 inches per second, drawing a 10-inch straight line of +/- 0.25 inches in all directions, implementing SCARA topology with two rotating joints to control the arm actuation, including a stop mode to allow the user to safely replace the utensil and selecting when the system will return to normal operations (ON/OFF switches), operate using G-code commands (G0, G1, G90, G91, G20, G21, M2, M6 commands), and halt within one second after user input to emergency switch and return to normal operation when reset. The main challenges our group faced were time constraints, busy schedules, meeting deadlines, and meeting the engineering requirements of the robotic arm and the physical components of the robotic arm. However, we overcame these challenges by working on our assigned blocks early and maintaining frequent communication to address any questions or challenges the group had. Effective communication played a big role in ensuring everyone’s success. Managing conflicting schedules required us to make sacrifices and prioritize essential tasks to complete the project efficiently as a team. With challenges came significant accomplishments. The group has done a good job of communicating with each other when we encountered a problem and put in the effort to push the final product out before the deadline. This shows that we were determined to finish the project and that we are committed to working our hardest when we must. For future improvements, we would like to fix the stability of the robotic arm and instead of using polymer, we would like to use real material that’ll last longer and look better.
