The 4DOF Acrylic Mechanical Arm Robot Manipulator Claw is an excellent DIY learning kit for anyone interested in robotics and mechanical engineering.
This unassembled version does not include servo motors, giving users full freedom to choose their preferred servo models for customization and performance.

Made from durable transparent acrylic, it allows you to clearly observe the movement and mechanism of each joint. Once assembled, it provides four degrees of movement – base rotation, shoulder, elbow, and claw grip. The structure is designed for easy installation with standard screws and nuts, making it an ideal choice for Arduino-based robotics projects and STEM education.

What is This Product?

This is a 4DOF Acrylic Mechanical Robotic Arm Kit, designed for educational robotics projects.
It helps you understand servo mechanics, robotic movement, and control systems. By programming it with Arduino, you can simulate real-world robotic applications like object picking, sorting, and automated tasks.

How to Use:

Start by carefully assembling the acrylic parts according to the included guide. Mount your chosen servo motors into the pre-cut slots and connect them to your control board (like Arduino).
Once connected, upload your servo control code to test each joint movement — base rotation, shoulder lift, elbow bend, and claw grip. With fine-tuning, you can make the arm perform tasks such as grabbing, moving, or stacking small objects.

Applications:

• Robotics learning & experimentation
• DIY Arduino-based automation systems
• Engineering & design training
• University or school robotics projects
• Maker lab & hobby projects

FAQ:

• Q1: Does it include servo motors?
  A1: No, servo motors are not included. You need to purchase them separately.
• Q2: Which servo motors are compatible?
  A2: Standard servo models such as SG90, MG90S, or MG995 are compatible.
• Q3: Can it be controlled by Arduino?
  A3: Yes, this kit is fully compatible with Arduino and similar controllers.
• Q4: Is this kit suitable for beginners?
  A4: Absolutely! It’s perfect for beginners, students, and hobbyists interested in robotics.
• Q5: Is the arm strong enough to lift heavy objects?
  A5: The lifting capacity depends on the type of servo motors you install. Heavy-duty servos can improve strength.
