MINI 3PI Car N20 Caster Robot Ball Wheel, Small Robotics Wheel

The MINI 3PI Car N20 Caster Robot Ball Wheel is a compact and lightweight support wheel designed for small mobile robots and mini robotic platforms.

It is specially suitable for 3PI robot cars and N20 gear motor based robots, providing stable rear or front support without affecting steering or drive performance.

The ball-type caster design allows smooth 360-degree free movement, helping the robot move easily in any direction while reducing drag and vibration.

Its small size makes it perfect for space-constrained robot chassis, lightweight vehicles and educational robotics kits.

This caster wheel improves overall balance and movement accuracy in line follower robots, smart cars, and small autonomous robots.
