Tamiya 70232 Chain-Program Robot STEM Kit for Beginners  [70232]

Tamiya 70232 Chain-Program Robot: Hands-On STEM Build

The Tamiya 70232 Chain-Program Robot brings practical robotics into a compact kit that is ideal for new builders and hobbyists exploring engineering basics. The assembly process highlights mechanical principles through step-by-step construction and visible moving parts.

Chain-Based Movement System

This model uses a chain-programming setup with three link types for forward, left and right moves, letting you assemble a physical program that guides the robot along a preset path. All assembly parts are supplied and the unit operates from one AA battery.

Modular Compatibility and Upgrades

The drive is powered by two Type 130 motors and the chassis features 3mm mounting holes to mate with other Tamiya Educational Construction Series components like plates and arms. There is room to install a small microcomputer for more advanced control, and the design can be converted to radio control with a separately sold 2-channel transmitter and double gearbox.

Learning Outcomes for Builders

Beyond being a model, the Tamiya 70232 Chain-Program Robot serves as an entry point to programming logic and simple circuitry, helping younger builders develop problem solving and hands-on skills in STEM contexts.
