Hi there, quick update. So I've been reading all of the responses posted so far, and they've given me a good perspective of the challenges this bot would face, as well as the difficulties of designing and building it as well. I still think the machine has potential, and I've already made a few adjustments to it (spikes on the sides (don't know why I forgot that in the original CAD), re-designing the wheels). I realize though that there are some things that I simply don't know enough of, such as pneumatics and gearing, that would make this type of build impossible for a first build. So I've decided that that I'll probably follow a different, far simpler path for my first featherweight, and put this one on the backburner. Linear actuators are something I didn't really consider, and I'd love to make a good control bot using them (I particularly like the design of the FW Aegis, building something like that would be nice). Hopefully I'll be able to learn a lot more at my first event, which I'm hoping will be before the end of the year. Thanks again everyone for the posts, they were of great help!
