 I hope that kids will stop asking us if we build Battlebots and start asking us if we build Transformers. To that, I will answer with a resounding yes. - Madison [more] |

It isn't pretty (yet), but extremely rigid.
All welds were done with MIG welder equipped with a spool gun. Still some more welding to do, but until then .. enjoy. I'm not sure of the weight as it is in that picture, but its somewhere in the neighborhood of 15~20lbs. Aluminum used, 2x1" 1x1" and 3/16" plate. The tubing is 1/8" wall.

Diggin the chassis there. I would never even think about trying to weld and get the wheel shaft holes to line up.

Ok, so maybe we cheated a little bit. Maybe these will clear it up ..
Basically, we took a solid aluminum rod, turned the outsides down enough to fit into the holes we drilled into the frame, and drilled out the center of the rod (all this was done on a mill and a lathe). Stick the 2 frame rails together, and it lines up perfectly. Clamp and weld. Once we welded the 4 2x1 braces in (you can see them in the top picture), we cut out tubes. Milled it down so 1/16" is outside the frame (so we didn't cut the entire weld off). Our wheels are going to be driven off the hub on the wheel, so the shaft doesn't have to spin. It took alot of machining, and work to get it right, but the final result is something that is dead on straight. Nothing worse than a robot that doesnt drive straight.

I'm impressed that it was done with MIG. I've only ever seen anyone attempt something like that with TIG. Great job guys!
