Tamiya 69931 Chain-Program Robot Kit Blue and Yellow  [69931]

Overview of the Tamiya 69931 Chain-Program Robot

The Tamiya 69931 Chain-Program Robot is a hands-on STEM model that encourages young engineers and hobbyists to learn core mechanical ideas. Its blue and yellow parts give the assembled robot a bright, workshop-ready look while the build teaches basic motion and programming principles through manual assembly.

Hands-On Mechanical Programming Basics

This kit explains engineering fundamentals using a chain-program mechanism. It provides three types of chain links that determine the robot's movement sequence. As the chain advances through the internal gears it shifts the rear wheel direction to steer the robot, offering a clear demonstration of mechanical programming without electronics.

Visual Appeal and Educational Display

The Tamiya 69931 balances function and style with vivid blue and yellow components plus white accents. Beyond lessons in mechanics, the finished model serves as an attractive display piece that highlights practical design and simple engineering.
