Tamiya 71102 Mechanical Kangaroo STEM Robot Kit  [71102]

Interactive STEM mechanics for young builders

The Tamiya 71102 Mechanical Kangaroo blends simple robotics and mechanical engineering to introduce core STEM ideas. The kit reproduces the distinctive hopping motion of a kangaroo using an inventive gear-driven mechanism.

See the gearbox in action

Transparent components expose the internal drive train that powers the rear legs. Two gear choices let you switch between a combined front-and-rear walking mode or a tail-supported stance that moves forward.

Simple assembly and adjustment

The parts are designed for straightforward assembly with a mix of screws and snap-fit pieces, plus marked points to help with wiring. Adjusting the tail changes steering and balance, giving users practical insight into motion and stability.

Where it performs best

Use the model on flat, smooth floors for reliable operation and to avoid stressing the mechanism. The quirky gait provides both entertainment and a clear demo of mechanical principles.
