Bob has a micromouse robot he designed, but unfortunately it had one fatal flaw... no, it diddn't have a broken good/evil switch (all Bob's robots come with only evil mode), It diddnt know when its battery was running low, so sometimes, it'd just die, killing the (expensive!) LiPo batteries in the process.

He wrote today's March Madness program to add basic battery monitor functionality to his robot, so he can stop bankrupting himself buying new batteries!
