TekBud Metal Ball Caster Wheel for Arduino Robotics Chassis DIY Bots

Durable & Compatible Design
Engineered for DIY enthusiasts and STEM projects, this caster features a hardened steel ball housed in a durable metal casing. Its low profile is perfectly matched to standard N20 and BO motors, keeping your chassis level to prevent sensor errors. Compatible with Arduino and Raspberry Pi kits, it offers a smooth, reliable glide for all your automated creations.

• ?? TRUE OMNIDIRECTIONAL MOVEMENT: Enables instant 360-degree rotation for differential drive robots. Eliminates drag to ensure precise turning for Line Followers and Maze Solvers.
• ?? OPTIMIZED FOR N20 & BO MOTORS: Low-profile design matches standard gear motors. Keeps your chassis plate perfectly level to prevent sensor tilt and ensure consistent traction.
• ??? LOW FRICTION STEEL CONSTRUCTION: Polished hardened steel ball minimizes starting resistance. Reduces torque load on micro-motors to maximize battery life.
• ?? PERFECT FOR STEM & DIY: Ideal for Arduino, Raspberry Pi, and ESP32 projects. Provides a stable third contact point for Smart Cars and autonomous bots.
• ?? EASY CHASSIS INTEGRATION: Pre-drilled holes allow quick attachment to acrylic or wood plates. A smoother, professional alternative to standard plastic drags.
