Tamiya 70198 Wall Hugging Mouse STEM Mini 4WD Kit  [70198]

Tamiya 70198 Wall Hugging Mouse STEM Kit Overview

The Tamiya 70198 Wall Hugging Mouse is an engaging educational kit that introduces core robotics ideas through build-and-run play. It combines simple assembly with visible mechanics so new builders can see how sensors and gearing work together.

Wall-Following Movement and Sensor Layout

This mouse-shaped Mini 4WD uses a basic sensing arrangement to detect walls and run in a zig-zag pattern along them. The transparent blue body gives a clear view of the internal parts, which helps learners study how the mechanism reacts to surfaces.

Quick Build with Screwless Parts

Assembly is straightforward thanks to a screwless construction and pre-wired components that reduce fiddly steps. That simplicity makes the kit accessible to beginners while still rewarding for more experienced builders looking to customise with other compatible parts.

Display Appeal and Run Time

Besides being an educational tool, the model has a fun look with stickers for eyes, ears and whiskers that make it great for display. It runs from a single AA battery (sold separately) and provides roughly six hours of operation on one fresh cell.
