Overview
The 68mm TT Motor Wheel is the standard wheel used in 90% of hobbyist robotics kits worldwide. Designed specifically to fit the “Double-D” output shaft of yellow plastic gear motors (TT motors), it provides a secure, snap-on fit without the need for additional hardware. Each wheel consists of a durable plastic hub and a removable rubber tire with a deep tread pattern, ensuring your robot doesn’t slip when navigating smooth surfaces or climbing small obstacles.
Key Features
Universal Fit: Perfectly compatible with all standard Yellow TT Gear Motors (single or dual shaft).
High-Grip Tread: The soft rubber tire offers excellent friction on tiles, wood, and concrete.
Tough Construction: The reinforced plastic hub is designed to withstand the bumps and crashes of early-stage robot programming.
Easy Assembly: No screws required—simply align the flat sides of the motor shaft with the wheel’s center and press-fit.
