Product Description

Optimize your robot's agility with the 7x2 cm Slim Robotic Wheels. These wheels are designed for builders who need a larger diameter for speed but require a slim profile to reduce friction and save space. At Robogears, we recommend the 7x2 cm size specifically for Line Follower and Micromouse robots where precise tracking and quick turns are essential. The slim 2cm width reduces the "scrub" effect during sharp rotations, allowing your motors to turn the robot with less resistance. Whether you are competing in a STEM robotics challenge or prototyping an autonomous navigator at your Pimpri workshop, these wheels provide reliable grip and consistent performance.

Detailed Key Features

  • Speed-Optimized Diameter: The 70mm height provides a higher top-end speed compared to standard 65mm wheels, perfect for racing applications.

  • Low-Friction Slim Profile: At only 20mm wide, these wheels offer less rolling resistance, which helps extend the battery life of your mobile robots.

  • High-Grip Rubber Compound: The tires are molded from a soft synthetic rubber that provides excellent "stikiness" on smooth surfaces like marble, wood, or competition mats.

  • Press-Fit 6mm D-Bore: Designed to slide securely onto standard yellow "BO" gear motors or metal gear motors with a 6mm D-profile shaft.

  • Lightweight Design: The spoke-style rim reduces rotational inertia, allowing your robot to accelerate and decelerate faster.

All Technical Details

  • Universal Hub: The center hub is compatible with a wide range of motor couplings, but it is optimized for the flat-sided 6mm D-shaft.

  • Removable Tire: The rubber tire can be removed from the plastic rim for easy cleaning or to replace it with custom silicon treads if needed.

  • Heat Resistance: The ABS rim is designed to withstand the ambient heat generated by motors during long-running robotic competitions.

  • Applications: Obstacle avoidance robots, Bluetooth-controlled cars, maze solvers, and educational physics experiments.

Prototyping & Engineering Tips (Robogears Exclusive)

  • The "Alignment" Check: At our Pimpri facility, we've noticed that slim wheels are more sensitive to axle alignment. Ensure your motors are mounted perfectly parallel; even a slight angle can cause a slim wheel to "wobble" more noticeably than a wide wheel.

  • Traction Maintenance: If your robot starts slipping on a smooth track, clean the rubber tires with a quick wipe of surgical spirit or soapy water. This removes the fine dust that builds up and restores the original grip level.

  • Speed vs. Torque: Remember that increasing wheel diameter increases speed but decreases the "pushing" torque. If your robot is very heavy, ensure your motors have enough torque (e.g., 150RPM or lower) to start the 70mm wheels from a standstill.

  • Securing the Shaft: If you are using high-torque metal motors, you can apply a tiny amount of hot glue or thread-lock into the D-hole before pressing the wheel on to ensure it never slips during sudden direction changes.
