Our Review
After integrating the Robot Arm Kit DIY 4 DOF Wooden Mechanical Arm with Sg90 Servos for Robotics Projects STEM Education SNAM1500 into several test builds, we found it to be a capable component for the price. Key specs include DOF: 3-axis, Reach: 200mm, Payload: 100g.
Assembly took about 1 hour following the included instructions. The fit and finish of the parts was acceptable — minor filing needed on a couple of pieces.
The platform provides a solid foundation for learning. We mounted an Arduino Uno, ultrasonic sensor, and motor driver without running out of mounting real estate. The acrylic frame is lightweight and easy to drill for custom mounts.
The Robot Arm Kit DIY 4 DOF Wooden Mechanical Arm with Sg90 Servos for Robotics Projects STEM Education SNAM1500 earns its place in the parts bin. Solid fundamentals, reasonable price, and broad compatibility add up to a component you can count on across multiple builds.
