Replacement 3pi Ball Caster with 1/2″ Plastic Ball

The Pololu Replacement 3pi Ball Caster with 12.7mm Plastic Ball is a versatile and essential component that was initially designed as a replacement part for the popular 3pi robot. This product also fits perfectly as a replacement part for the newer 3pi+ robot, which has the housing for the ball built directly into the chassis. The ball caster can also be used as a general-purpose ball caster, providing versatility and flexibility for your robotics projects.

One of the key usage examples of this ball caster is when it's mounted through a hole in a chassis that uses Pololu's micro metal gearmotors and 32x7mm wheels, similar to the 3pi robot setup. In such a configuration, this ball caster maintains the right height to keep the chassis level. This makes it an excellent choice for those looking to build their own robot designs or replace parts in existing robots.

One of the key benefits of this ball caster is its compatibility with both the 3pi and 3pi+ robots. This means that it can be used as a reliable replacement part, ensuring that your robot functions optimally. Its general-purpose functionality also allows it to be used in a variety of other applications, providing you with the flexibility to use it as you see fit.

What sets this ball caster apart is its unique design and high-quality construction. With a 12.7mm plastic ball, it is robust and durable, ensuring longevity and reliable performance. Whether you're a hobbyist or a professional, the Pololu Replacement 3pi Ball Caster with 12.7mm Plastic Ball is a valuable addition to your robotics toolkit.
