Tamiya 70223 Friction Powered Snail Classroom Model  [70223]

Practical STEM building with the Tamiya 70223 snail

The Tamiya 70223 Friction Powered Snail is an accessible assembly project that helps users grasp mechanical fundamentals by constructing the model. Part of Tamiya's Educational Construction Series, it shows how friction can power motion without relying on batteries.

Transparent drive and adjustable motion

The friction assembly is housed in a clear casing so the rotating components and linkages can be inspected while running. Changing the crank base alignment alters the snail's wag and nod, allowing simple tests in motion variation.

Durable parts and obstacle response

The body and shell are formed from two polypropylene sheets for a durable but light build. Functional antennae help guide the model around small obstacles and a clutch protects the gears from overload.
