4-Finger Robotic Arm Mini Mechanical Gripper Kit with N20 Motor DIY

The 4-Finger Robotic Arm Mini Mechanical Gripper Kit with N20 Motor is a compact and educational mechanical claw designed for robotic arm projects, DIY robotics, and mechanical training. Built with durable 3mm black acrylic plates and 3D printing Technology and powered by a 6V N20 motor, this mini gripper provides smooth and realistic gripping motion, ideal for teaching mechanical structures or integrating into custom robotic arms.

The model features a 4-finger gripping mechanism that operates simultaneously through the motor’s transmission system, providing reliable control for lightweight gripping and motion demonstrations. It’s suitable for desktop display, school experiments, and robotics research, and can also be mounted onto robot arms or custom-built mechanical platforms.
