Tamiya 70068 Wall Hugging Mouse Educational Kit

The Tamiya 70068 Wall Hugging Mouse is a hands-on STEM kit aimed at curious builders and hobby enthusiasts. Its two-motor drive lets the model travel alongside walls while a sensor rod triggers a switch to change direction, producing the signature zig-zag motion. This setup gives a straightforward demonstration of simple circuits and mechanical response.

How It Navigates

The mouse uses two RE-140 motors that shift steering when the sensor rod touches a wall. The rod actuates a micro switch which alters motor function so the mouse can follow the wall. Watching the sequence helps illustrate cause and effect in motion control systems.

A Simple STEM Build

Constructed from resilient polycarbonate and plastic parts, the kit is accessible for beginners yet satisfying for more practiced builders. It works well as a first step into robotics and basic electronic switching for workshop sessions and classroom projects.
