Mini 3PI Car N20 Universal Castor Ball Wheel

The Mini 3pi generally refers to a smaller variant or derivative of the Pololu 3pi robot design. While Pololu doesn't officially produce a "Mini 3pi," many robotic hobbyists and manufacturers create miniature versions of the 3pi concept, optimizing it for ultra-compact projects.

Key Features of a Mini 3pi Robot (Hypothetical or Custom Build):

1. Compact Size:

   • Smaller than the original 3pi, making it suitable for tight spaces or smaller tracks.

   • Typically designed to retain the circular shape for balance and movement.

2. Simpler Hardware:

   • May use smaller motors like N20 gearmotors for mobility.

   • Lightweight components like mini caster wheels or plastic chassis to reduce weight.

3. Core Functionality:

   • Includes line-following or maze-solving capabilities, similar to the full-sized 3pi.

   • Equipped with essential sensors like IR reflectance sensors but fewer in number.

4. Lower Cost:

   • By scaling down the components and features, a Mini 3pi is usually more affordable.

   • Ideal for beginners or budget-conscious robotics enthusiasts.

5. Examples:

   • Some DIY projects label their scaled-down 3pi-inspired robots as "Mini 3pi."

   • Mini robots often pair well with small wheels, compact chassis, and lightweight ball castors like the Mini 3PI Car N20 Caster Robot
