Tamiya 71121 2-Legged Walking Robot - Wind-Up Robocraft Kit  [71121]

Tamiya 71121 - Wind-up Two-Legged Walker

This Tamiya 71121 kit delivers a practical build experience for hobbyists and STEM students. The two-legged walker runs without batteries by using a wind-up generator, and can be configured to mimic either an ostrich or a duck for a blend of learning and display value.

Mechanics and Movement

The design highlights simple mechanical principles so builders can see how motion and energy conversion work. A hand crank generator provides the drive, allowing the model to move forward or reverse with a turn of the handle. A 50cm cable links the generator to the walker for flexible positioning during operation.

Learning Benefits and Hobby Use

Well suited to classroom projects or weekend builds, this kit encourages hands-on exploration of gears and linkages. The choice of two bird styles adds a creative element, making the finished model suitable for demonstration or gentle play with supervision.
