Tamiya 89901 Mechanical Rabbit Educational Display Model  [89901]

Introduction to the Mechanical Rabbit

The Tamiya Mechanical Rabbit is a Robocraft-style finished model that showcases basic mechanical movement for hobbyists and educators. The design uses a crank and link-rod mechanism so left and right legs move together, transforming motor spin into a stepping action. An internal gearbox eases the motor rotation for controlled motion.

Transparent construction and learning points

The almost-clear body offers a full view of the moving linkages and gear train, making it useful for demonstrating mechanical concepts in a tangible way. The motor and battery compartment are located at the front so the rear legs are free to operate without obstruction.

Compact size for display

With an overall length of 115mm, the Mechanical Rabbit fits neatly on a shelf or workbench while still providing visible engineering detail. It is intended for display and educational use rather than performance running.
