Want to carry a stack of 6 totes? You'll have to solve this problem.
15 lbs representative electronics (lower yellow area)
20 lbs representative front lift (vertical yellow area)
realistic drive train, with WCP gearboxes, 4 CIMs and battery in the very back.
45.4lb 73" red stack of totes.
Scale your ambitions accordingly!

Re: pic: 6 Stack Conundrum
Even if the robot was not designed exactly like this, does anyone worry about the axles on a west coast drive bending for the weight?

Cool, so it's a really hard engineering competition!! How great is that!
And here everybody thought it was going to be stupid boxes moving around with dozers.
Love me some hard engineering problems.....

This 'conundrum' makes the important assumption that you don't have outrigger wheels to stabilize, a counterweight, or a way of taking the boxes further into your wheelbase.

Forklifts are designed to tilt the stack a little backwards.

Jesse brought up a really good point which I haven't really thought of, the weight shifts substantially when with and without totes. I'm curious to see if going onto the scoring platform with the totes would cause us to tip.

I'm surprised more on the plausibility of picking 6 up in a single stack hasn't come up from a tote integrity point of view. One of the Ri3D videos had a good demonstration of the damage that happens to the bottom tote when multiple totes are stacked on top of it while it's lifted by the single finger.
