Tamiya 70248 Roller Skating Robot Educational STEM Kit  [70248]

Practical STEM learning with the Tamiya 70248 kit

The Tamiya 70248 Roller Skating Robot provides a clear demonstration of simple mechanical motion via an accessible assembly process. It is designed to help learners and hobbyists understand movement and linkages in a compact model.

Movement pattern and steering explanation

The unit uses a swizzle style motion where the legs open and close to generate forward travel. Steering is managed by small adjustable rudders on the skate plates so you can tune left or right bias. The transparent blue body exposes the drivetrain while the plain white shell is aimed at those who want to decorate or paint their model.

Assembly notes and power details

Assembly combines snap-fit components with a few screws, keeping it approachable for a wide range of skill levels. It is driven by a Type 130 motor and requires one AA battery (sold separately), giving a top speed of about 33.3 cm/s. There are optional universal arms available separately for rail-based demonstrations.
