Tamiya 70068 Wall Hugging Mouse STEM Learning Kit  [70068]

Tamiya 70068 Wall Hugging Mouse Learning Kit

The Tamiya 70068 Wall Hugging Mouse is part of the STEM lineup, offering a compact build that demonstrates mechanical feedback and switching. Its two-motor configuration propels the model while a sensor rod contacts a wall to operate a micro switch, producing the characteristic zig-zag tracking. The project gives clear insight into elementary robotics and circuitry.

Core Mechanism

The mouse makes use of two RE-140 motors that alternate steering when the sensor rod senses a surface. Contact triggers the micro switch which adjusts the motors so the chassis can continue alongside the wall. This straightforward arrangement is useful for understanding how sensors influence motion in simple robots.

Assembly Notes

Components are moulded from sturdy polycarbonate and plastic, and the kit is presented in a way that suits newcomers and experienced builders. It is a practical educational model for demonstrating motion, control and basic electronic switching in a compact package.
