You need Forward and LeftRight - Spin as well.Also Spin is a button not a switch.These bindings are for Pillar.py and FBS.PY - you can use Whipper that will use a smartzone, and no Spin command.Get Phil's (and Mad's) AI-Chart-2.3 if you're starting to AI.
Since the hammers aren't going through the chassis, shrink its length a bit (but the not width, you're gonna need the wide stance). And try using the longest ME and attach the perm to that. Maybe you'll have the weight for the motor armor.
the static axe will be like a tail. pushing against the ground so you can acually use it to move forward.that bot is tough! i battled him and it is extremely had to hit the chassis.
To answer your question, this kind of bot has been made before many times.
