As your creation breaches the south wall of the first bank of YourTownVille, it continues northward towards the vault, when suddenly, your nemesis comes in from the east and shorts out your high-amperage H-Bridge with a hero-themed thrown metal projectile, frying the MCU with back-voltage and costing you thousands in robot parts and lost potential loot from the bank, while saving the day and getting the girl. Typical hero stuff.
If only you had had the foresight to install a vision system that could have panned with the extra analog stick on that gamepad you were driving the machine with from your yacht afloat in international waters...
Well, here is one way to build such a system. (I hope no one got tired of the evil mad scientist scenario above)
