The little servo in the Hummingbird range. Lower torque and lower cost than the full-size units, and small enough to hide inside a cardboard puppet or a lightweight walking robot.
Good for expressive faces, flapping wings, moving arms and any build where the mass of a standard servo would be a problem. Plugs into a servo port on the Hummingbird controller; compatible with both the Hummingbird Bit and the Hummingbird Duo.
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.
