that's awesome, wish he had a writeup on the build, very interesting tech solutions in that rig - the wheels are driven by chains, i thought it had hydraulic converters before i read the comments

This would also be possible with electric motors at each wheel.

I wonder what that thing would score on an RTI ramp!!!

It would have to be a very big ramp!

As a practical vehicle I'd rather have standard axles.  I've heard they did enter it in some comps but it was too cumbersome to drive.

Since one axle powers both, it's a bit of a week link. Pretty out of the box thinking thou.

Like just about anything mechanical it is a process of development.  With electric motors at each wheel, the mechanical complexity would come way down and the link design could be optimized without worrying about the chains running to each wheel. 

Active suspensions that move to keep near equal weight on each tire might greatly improve traction and could keep the vehicle more level compared to what we use now.  Imagine keeping a vehicle level on an off camber slope (much harder to roll it) or not losing traction on a drooping wheel (it should not be drooping but instead holding the vehicle up).  I really hope to see these things in use in coming years (but I'll stick to leaf springs anyway).

Thats awesome, I would use some hydraulic motors with some geared hubs, might not move very quick but it would def have some torque to it, although the JLG lifts I used to work on seemed like they could move pretty quick
