5-DOF Robotic Arm – NEMA 23/NEMA 17 with Timing-Belt Reductions · 模型 121113
This is a CAD model of a 5-DOF robotic arm designed for robotics research, prototyping, and educational applications. The arm provides the following movements: Base rotation Shoulder pitch Elbow pitch Wrist pitch Wrist yaw Motor configuration: Base: 1 × NEMA 23 stepper motor, 82 mm body length Shoulder: 1 × NEMA 17 4401S stepper motor Elbow: 1 × NEMA 17 4401S stepper motor Wrist pitch: 1 × NEMA 17 4401S stepper motor Wrist yaw: 1 × NEMA 17 4401S stepper motor Transmission system: Base rotation: 10:1 timing-pulley speed reduction Shoulder joint: 4:1 timing-pulley speed reduction Elbow joint: 4:1 timing-pulley speed reduction Wrist joints: Direct drive The pulley reductions increase the available joint torque and improve positioning resolution while reducing the joint speed. Please note that this upload primarily presents the mechanical design. Motor performance, payload capacity, accuracy, and structural strength should be verified before manufacturing or operating the arm with significant loads.
