Rubber Wheel 136×24mm (Kit)

DFRobot 136mm Rubber Wheel Kit is a durable mobility solution designed for indoor service robots and custom mobile platforms. The robotics wheel set integrates two large‑diameter rubber tires, precision shaft couplings, and mounting hardware to simplify drivetrain assembly. Engineered specifically for smooth indoor operation, the traction‑optimized tire pattern improves grip on common floor surfaces while maintaining stable motion and low rolling noise. Designed to pair directly with DFRobot HCR (Home Care Robot) platforms and similar robotic bases, this mobile robot wheel system provides a reliable mechanical interface for building service robots, research prototypes, and autonomous indoor transport platforms.

Enhanced Indoor Traction Design

This robotics wheel assembly features custom‑molded rubber tires with anti‑slip surface indentations that improve grip across a range of indoor environments. Extensive testing across multiple floor conditions validates stable traction and reliable maneuverability for service robots and mobile research platforms. The 136 mm outer diameter helps maintain smooth movement while overcoming small floor transitions, making the mobility component suitable for indoor navigation tasks that require consistent contact with polished floors, tiles, or laminated surfaces.

Integrated Coupling System for Easy Installation

The robot wheel package includes dedicated shaft couplings, washers, and M8 screws, forming a ready‑to‑install drivetrain interface. The internal M8 threaded coupling and shaft collar structure secure the motor shaft firmly and reduce slippage during operation. Compatibility with the 12V high quality and quiet DC Motor from DFRobot simplifies integration with common robotics drive systems, while also allowing custom couplers when alternative motor shafts or mechanical configurations are required.

Designed for HCR and Custom Robot Platforms

Originally developed for the HCR - Mobile Robot Platform, this large rubber wheel pair also supports a wide range of indoor robotic chassis builds. The mechanical structure and mounting hardware enable quick integration into DIY robot bases, educational robotics experiments, and prototype service robots. As a versatile indoor mobility component, the wheel system supports reliable motion control for robotics research labs, maker projects, and robotic platform development.

Typical uses include indoor service robots, custom mobile robotics platforms, and experimental robot bases requiring stable traction and simple drivetrain assembly. The large rubber wheel design combined with integrated couplings provides a practical mechanical foundation for robotics mobility development.
