Tamiya 70259 - Penguin Walker and Swimmer STEM Kit  [70259]

Introduction to the Tamiya 70259 penguin kit

The Tamiya 70259 Walking & Swimming Penguin brings the Robocraft series to life with a hands-on build that demonstrates simple mechanics. Designed to imitate a penguin's gait and swimming stroke, this kit is suitable for hobbyists and young model makers who want to see motion conversion in action on land and in water.

Mechanical layout and motion

On dry surfaces the model moves using a clever linkage that converts the supplied submarine motor's rotation into coordinated leg and wheel action. Side wheels attach to each leg and a central front wheel helps create the penguin's distinctive wobble as it advances. In the water, the same drive turns the flippers while a neck float maintains buoyancy and stability.

Operation on land and in water

The build allows simple steering adjustments by changing wheel or flipper orientation, making it useful for demonstrating directional control in both environments. Parts are plastic and can be painted for personal styling, letting builders customise the finished model.
