Robot Car Rubber Wheel for TT Motor

Build a smoother and more reliable DIY robot car with this Rubber Wheel for TT Motor, a popular wheel-and-tyre assembly made for standard yellow TT/BO geared DC motors. It is commonly used in 2-wheel-drive and 4-wheel-drive robot chassis kits because it fits directly on the motor shaft without requiring a separate coupler, pulley or gearbox adapter. The outer rubber tyre improves traction on typical indoor surfaces such as tile, laminate, cardboard, acrylic sheets and classroom floors, helping your robot move with less wheel slip compared to hard plastic wheels. The wheel uses a lightweight plastic rim with a push-fit centre hub matched to the output shaft profile of common TT gear motors. Once pressed onto the shaft, it rotates with the motor to provide simple, low-cost drive for battery-powered robot platforms. It is suitable for Arduino, Raspberry Pi, ESP32, micro:bit and other controller-based projects when paired with a suitable motor driver such as L298N, L293D, TB6612FNG or a compatible DC motor driver board. This TT motor rubber wheel is a practical choice for line follower robots, obstacle avoiding cars, Bluetooth/ Wi-Fi controlled vehicles, maze solving bots, school science projects and prototyping small automation mechanisms. Makers can use two wheels plus a caster wheel for a 2WD robot, or four wheels with four TT motors for a 4WD chassis with better traction and load distribution. What you get: 1 piece robot car rubber wheel for TT motor. Motor, chassis, screws and electronics are not included unless specified separately. Pin notes are not applicable because this is a mechanical wheel; for best results, push the wheel straight onto the TT motor shaft and ensure both left and right wheels are aligned before running the robot.
