Well, it's back to square 2.5, as the robot... Imploded, really. The place where the bars joined was melted, not welded, so as I was drilling (Managed to break a drill bit, and hurt me thumb ) The side snapped in on itself. Tomorrow, I'll be ordering a 1000 by 500 mm by 12mm Sheet of HDPE, and I'm going to make something hopefully working. A four wheel (Chain Driven) Two motor axe bot. Made from HDPE and a layer of steel.
