Custom 5-DOF Robotic Arm (Designed by a 9th Grader) This five-degree-of-freedom robotic arm was engineered entirely from scratch. The base rotation turret features a custom bearing assembly driven by a NEMA 23 stepper motor for high torque. - Axis 2 utilizes a NEMA 17 motor with a 16:60 belt-driven gear ratio for torque also. - Axis 3 is powered by another NEMA 17, dedicated to rotation. - Axis 4 introduces an angular joint mechanism, also actuated by a NEMA 17, enabling complex wrist-like movements. - Axis 5 provides another rotating motion, completing the arm's full range of motion. To print all the materials for my projects and exhibitions, I always prefer the Core One. It's fast, reliable, and more heavy-duty for materials like ASA, ABS, and CF. This project has all parts printed using a sponsored Prusa Core One. The filament I used was Overture ASA (sponsored as well).

Hi, I'm Siva. Currently (2025) a freshman at Amador Valley High School, and I’m passionate about building, designing, and hands-on engineering. I do most of my CAD work in Onshape—it’s been my go-to platform for everything from robotics mechanisms to event-ready prototypes.
