The 3-DOF robotic arm features a linkage structure arranged in a parallelogram configuration. This design eures that the Gripper remai parallel to the ground throughout operation. In this project, I used a Nema 23 Stepper motor for State 1, and two DS5160 Servo moto for State 2 and 3. Additionally, I used 16mm Aluminum shafts (with 2mm wall thickness) and 6mm Aluminum shafts for structural components. The other parts were fabricated using 3D printing 3-DOF robotic arm was designed quite some time ago. At that time, my experience, knowledge, and overall design skills were still limited. As a result, there are several fundamental design flaws in this veion. Therefore, this drawing should be used for reference purposes for your attention.
