Tamiya 70198 Wall-Hugging Mouse

Tamiya’s wall-hugging mouse is a fun and easy-to-build kit that’s great for new robot enthusiasts, and it can serve as a unique, hackable robot chassis for more advanced users. The mouse has no digital electronics; rather, a simple wire bumper along its side directs current to one of two motors to keep the mouse moving along the wall. The mouse features a hard plastic shell and runs on one alkaline AA battery.
