Tamiya 89902 Finished Mechanical Turtle Model - STEM Robot Creature  [89902]

Mechanical Turtle in the Robocraft Lineup

This finished Tamiya model showcases basic mechanical engineering in an accessible format. The Mechanical Turtle appeals to model collectors and those exploring simple robotics, providing a clear example of motion transfer in a small package.

Linkage and Motion

Power from a compact motor is routed through crank plates to the leg assemblies, producing the alternating leg movement. The front leg plate is attached with a ball joint, creating a pivot that helps the model crawl in a convincing manner.

Power Needs

The model runs on a single R03/AAA/UM4 battery, not included in the box. Because it uses a small cell, the turtle stays lightweight and easy to move when you want to show the mechanism to others.
