So you instantly moved on to a new bot, without listening to advice? Please. Do not stray down my path. It is filled with spiders and downrep. And Chain Of Impending Doom. Anyways, Taz wheels are not good, use 2 ants with some battlepacks for electricity, the pistons seem too wide, You could easily make a row of beaters or sledgehammers instead of this specific system, and the bot wideness is unnecessary.
