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

What the Tamiya 69931 Chain-Program Robot Teaches

The Tamiya 69931 Chain-Program Robot is an instructional model aimed at newcomers to mechanical systems and hobby builders. The blue and yellow components are easy to identify during assembly and help illustrate how parts interact to produce motion.

Practical Chain-Program Mechanism Explained

This kit shows how a chain-program arrangement can direct movement. It comes with three chain link variations that control different steering patterns. When the chain cycles through the gearbox the rear wheels change direction, demonstrating programmable motion without electronic controls.

Display Potential and Educational Merit

Beyond its teaching value, the Tamiya 69931 has a neat colour contrast with white accents that make the assembled robot suitable for display in a study or workshop. It highlights mechanical thinking in a compact package.
