The Wall Mite
This is an improvement on the same concept that my "Eldritch Abomination" uses, that robot can be found here: http://robocraftgarage.com/robot/abptyBIT
Unlike the Abomination the Wall Mite is much, much tanker. It still dies rather quickly if attacked, but won't die from single bomber droppings. It dose not use any rudders which makes it hard to control some times, but gives it great speed.
Like it's predecessor it sticks to walls in order to get the stability it needs to snipe. Its orientation is kept constant trough helium at the top part and normal blocks at the bottom part.
