Product Description

The 70 x 12mm BO Motor Wheel is a high-performance movement solution engineered for precision and durability in mobile robotics. Specifically designed for the "Battery Operated" (BO) gear motor series, this wheel features an upgraded rubber tread pattern that provides superior friction on both smooth indoor tiles and rugged outdoor surfaces. At Robogears, we prioritise mechanical stability; hence, these wheels utilise a reinforced nylon hub, which offers significantly better impact resistance than standard ABS plastic. Whether you are building a high-speed line follower or an autonomous explorer in your Pimpri workshop, these wheels ensure your robot maintains its path with maximum grip.

Detailed Key Features

  • Maximum Traction Tread: Equipped with a soft rubber tyre featuring an anti-slip pattern to prevent "spinning out" during rapid acceleration.

  • Reinforced Nylon Core: The inner rim is made from heavy-duty nylon, providing a rigid foundation that won't warp or crack under heavy project loads.

  • Precise Push-Fit Bore: Features a 6mm D-hole centre bore for a secure, tool-less connection to standard yellow plastic gear motors.

  • Optimised Ground Clearance: The 70mm diameter ensures your robot can navigate over small bumps and uneven terrain without bottoming out.

  • Integrated Vibration Damping: The flexible rubber compound acts as a natural shock absorber, protecting sensitive onboard sensors and microcontrollers.

All Technical Details

  • Tread Design: Zigzag or standard anti-slip pattern for multi-terrain versatility.

  • Weight Profile: Optimized for low rotational inertia (~35g) to extend motor life and battery runtime.

  • Shaft Interface: Designed specifically for the "Double D" output profile of plastic gear motors (5.4mm round / 3.5mm flat edge).

  • Load Rating: Capable of supporting up to 2.5 kg when distributed across a standard 4-wheel robotic platform.

Prototyping & Engineering Tips (Robogears Exclusive)

  • Secure Installation: To install, align the flat edge of the BO motor shaft with the internal flat of the wheel hub. If the fit feels too tight, a quick 10-second blast from a hairdryer on the hub can make the nylon more pliable for a perfect seated fit.

  • Traction Restoration: If the wheels lose their "tackiness" due to dust, wipe the rubber tyres with a damp cloth or a small amount of isopropyl alcohol to restore original grip.

  • Balanced Design: For 4WD systems, ensure all wheels are pushed equidistant onto the motor shafts to prevent the robot from "pulling" to one side.

  • Gearing Considerations: A 70mm wheel provides a higher top speed compared to a 65mm wheel but requires more motor torque. Ensure your BO motors are 150-300 RPM for the best performance.

Package Includes

  • 1 x 70 x 12mm BO Motor Wheel
