Our Review
After integrating the KLAYERS SO-ARM101 SE Open-Source 6-Axis Robotic Arm, Native Support for Hugging Face LeRobot, High-Torque Bus Servo,NO 3D-Printed Parts into several test builds, we found it to be a capable component for the price. Key specs include DOF: 3-axis, Reach: 300mm, Payload: 500g.
Assembly took about 1.5 hours 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.
For the price point, the KLAYERS SO-ARM101 SE Open-Source 6-Axis Robotic Arm, Native Support for Hugging Face LeRobot, High-Torque Bus Servo,NO 3D-Printed Parts delivers what you need without unnecessary complexity. Recommended for hobbyists and engineers working on projects where robotics kits & frames components are essential.
What We Like
- Open-source or well-documented wiring diagrams available
- Sturdy construction withstands crashes during testing
- All mechanical hardware (nuts, bolts, spacers) included
- Compatible with popular Arduino and Raspberry Pi boards
Watch Out For
- Software examples are basic and need expansion for real projects
- Screws and standoffs are metric — imperial tools will not fit
- Controller board not included on many frame-only kits
