Buying guide
SG90 servo buying notes
The SG90-style micro servo is the budget choice for lightweight robot-eye tests, low-cost prototypes, and basic motion experiments. It is useful when the goal is to test geometry before choosing a quieter premium servo.
- Sold as a single servo; use quantity 6 for the dual-eye 4-DOF setup.
- Best for lightweight tests and simple prototypes.
- Use six matching servos instead of mixing servo models in one dual-eye mechanism.
Choose the right build path
| Build path | Best for | Choose when |
|---|---|---|
| Single-eye prototype | Low-cost movement tests and education demos | Noise is acceptable and the mechanism is lightweight. |
| Dual-eye budget setup | Paired-eye motion testing | You need six matching servos and want a lower total hardware cost. |
| Premium display build | Close-range animatronics and quiet robot faces | Choose the quiet digital servo instead if motor noise would hurt the final presentation. |
Product questions
How many SG90 servos do I need for dual-eye 4-DOF movement?
Use quantity 6 for the Robot Eye Kit dual-eye 4-DOF setup.
Is SG90 quiet enough for a finished animatronic head?
It can work for prototypes, but quiet digital servos are better for close-range finished displays where servo noise is noticeable.
Can I mix SG90 and quiet digital servos in the same frame?
It is better to use six matching servos so speed, centering, torque, and noise behavior stay consistent across the mechanism.
