Reproduction
Servo Mini Arm
A reproduced servo arm extended with my own joystick circuit and control code to learn through a deliberately light-duty mechanism.

Original design files remain on MakerWorld; this page shows only my build and joystick-control evidence.
- Why I built it
- I wanted to understand why people build small servo arms and explore the control side for myself.
- My contribution
- I printed, assembled, and wired the arm, then built the joystick circuit and wrote the control code.
- Main constraint
- The original arm geometry and small servos limited stiffness and payload.
- Observed result
- Joystick control worked as intended. The arm could pick up and grab items below 20 g.
- What fell short
- Payload capability was very limited, and the arm was not stiff enough for heavier objects.
- Next iteration
- Design a stiffer, more robust arm from scratch.
