A pair of rubber-tyred ABS wheels designed to fit N20 mini metal gearmotors and compatible Solarbotics metal gear motors. The hub features teeth that can be used with a reflectance sensor for encoder feedback, adding speed and position sensing to your robot.
The wheels press-fit onto the gearmotor output shaft — initially sliding in easily, then achieving a snug fit at the far edge of the hub. For Solarbotics motors with shorter shafts, mount from the opposite side where the fit is tighter.
Key Features
- Rubber Tyre – Good grip on smooth surfaces
- Encoder-Ready Hub – Built-in teeth for reflectance sensor feedback
- Press-Fit Mounting – Fits N20 and compatible gearmotor output shafts
