Subject: [alt-beam] Re: My walker ain't walkin'
On my bots, to balance them, I try to get it so I can get it to sit on
three legs, and if i tilt it, it'll sit on 3 legs in the opposite angle.
If it falls back quickly or forcibly, you need to move your weight away
from where it falls. It is OK if it falls back lightly, usualy. That's
how I generaly do it anyway.

everyone thinks they are dead :) I have just been REALLY busy working on
tons of different projects. I have been working on the page here and there
getting ready for a big update. I don't know when it will be though. I'd
like to at least finish off all the pages (circuits page, PCB's page...).
Sorry I haven't been updateing.
