If you bought a servo from us you probably got a bunch of plastic add-ons that you can snap onto the rotating part of the servo. These are called 'servo horns'. For many robotics projects you'll end up drilling or gluing to the horns to attach it to your armatures. But maybe you messed up, or you want to recycle the expensive motor part? This product comes with just the horns! No servo is included, so you can reuse the motors you've got.
They mate with 25-tooth servo axles. We've found they're compatible with our standard-size servo motors:
- Continuous Rotation Servo - Feetech FS5103R
- Standard Servo - TowerPro SG-5010
- Standard Size - High Torque - Metal Gear Servo
But it will not fit neither the Parallax Feedback 360 Degree High Speed Continuous Rotation Servo nor micro and sub-micro servos.
Jargon buster
Plain-language definitions for the technical terms used above.
- servo
- A servo is a motor with built-in position control, usually told to move to a specific angle by a control signal. It matters when you need repeatable movement, such as steering, arms, flaps, or linkages, rather than continuous spinning.
- Torque
- A twisting force that causes something to rotate, usually measured in newton-metres or kilogram-centimetres. It matters when choosing motors, servos, gears, and tools because higher torque is needed to lift heavier loads, turn larger wheels, or move mechanisms without stalling.
