That thing is crazy. Im guessing ackerman steering. Definitely very cool
Hmmm that looks like the workroom at Waterjet cutting of Indiana.
If I know those guys, I would say you are wrong 
COOL! thats an awesome way to build a robot. What steps did you take to align the parts for welding?
Looks like a Rookie-All-Star chassis to me.
Oh dear. That is the hottest frame I have seen like, ever. My first thought was also ackermann/forklift drive.
Is the final going to be X-shaped or is there something around it? Looks like any bumper mount would be pretty weird in the current configuration…
WOW – how much does it wiegh?
I wouldn’t call it an Ackerman, but you’re going down the right path. It is a modified crab drive system with two steer motors and many options to go with it.
As for the welding, used a method with tabs and notches so the parts went together like a big puzzle. Weighs about 20-25lbs.
