Product Description

Equip your mobile robot with superior traction using the 7x4 cm Robotic Wheels. These wheels are specifically designed for medium-sized robots that require stability and a wide contact patch to handle diverse surfaces. At Robogears, we recommend these wheels for "All-Terrain" hobbyist builds because the 4cm width provides a significant footprint, preventing your robot from sinking into soft surfaces like sand or thick carpets. The soft rubber tread features deep grooves for maximum friction, ensuring your robot can climb inclines without slipping. Whether you are building a wireless surveillance rover or an autonomous delivery bot at your Pimpri workshop, these wheels offer the perfect balance of durability and grip.

Detailed Key Features

  • High-Friction Rubber Tread: The outer tire is made of high-quality synthetic rubber that grips smooth tiles and rough asphalt with equal efficiency.

  • Reinforced ABS Rim: The internal hub is constructed from impact-resistant plastic, designed to withstand the torque generated by high-power gear motors.

  • Universal 6mm Bore: Fits most standard "BO" (Battery Operated) motors and metal gear motors with a 6mm D-shaft.

  • Track-Style Design: The wide 40mm profile provides "tank-like" stability for four-wheeled or six-wheeled robotic chassis.

  • Shock Absorption: The semi-flexible rubber helps dampen vibrations, protecting your sensitive onboard sensors like IMUs or Cameras.

All Technical Details

  • Coupling Compatibility: Features a standard center hole for 6mm shafts; some variants include a side-screw (grub screw) hole for extra secure fastening to metal shafts.

  • Directionality: Symmetrical tread design allows for consistent performance in both forward and reverse directions.

  • Environmental Resistance: The rubber is resistant to common oils and floor cleaners, making it suitable for indoor industrial floor-mapping robots.

  • Applications: Line-following robots, fire-fighting bots, RC heavy-duty trucks, and automated guided vehicles (AGVs).

Prototyping & Engineering Tips (Robogears Exclusive)

  • Shaft Fitment: At our Pimpri facility, we've noticed that different motors have slightly varying shaft tolerances. If the fit is too tight, heat the shaft slightly before pressing the wheel on. If too loose, a small drop of thread-locker or a thin layer of Teflon tape on the shaft will provide a firm seat.

  • Calculating Speed: To estimate your robot's speed, use the wheel's circumference: $C = \pi \times d \approx 3.14 \times 70mm = 219.8mm$. Every rotation of the motor moves your robot approximately 22cm.

  • Cleaning the Tread: Over time, rubber wheels pick up dust, which reduces grip. Wipe them with a damp microfiber cloth or a bit of isopropyl alcohol to restore their original "sticky" traction.

  • Torque vs. Speed: These 70mm wheels provide a higher top speed than standard 65mm wheels but require slightly more torque from the motor to start moving. Ensure your Motor Driver (like an L298N or TB6612FNG) can handle the startup current of your gear motors.
