Tamiya 70168 Double Gearbox Kit with Independent 4-Speed Control for STEM and Robotics  [70168]

Tamiya 70168 Double Gearbox - Practical STEM Gearbox for Hands-on Learning

The Tamiya 70168 Double Gear Box gives hobbyists and students a clear way to study mechanical advantage through building and testing. It offers four selectable gear ratios so you can choose either higher speed or greater torque, making it a solid pick for educational projects and small custom robots.

Dual Independent Drive for Testing

This double gearbox is set up with separate left and right drives, so each side can run a different gear ratio. That arrangement encourages experimentation with differential behaviour and helps demonstrate how gear choices affect motion and load handling.

Robust Parts and Included Motor

Made from sturdy plastic, the Tamiya 70168 is built for repeated classroom use. The kit includes an FA-130 type motor, a motor cover, and a crank arm so you can integrate it into a build right away.
