“his “level up” from your basic brainless bristlebot has the capacity to seek out or “run away” from light sources. Its great fun to lead through a maze with a lighter or torch - like a moth to the flame. Install the light sensors the other way around and it takes on cockroach characteristics, moving away from the light. This design also employs a capacitor to power the motor, allowing for endless recharges. A great “next step up” project for fine tuning your soldering techniques. In my experinece total beginners (11 year olds with no previous soldering experience) can manage these but need a little support and guidance here and there.”
