Re: pic: What about this???

I would step down to 1/8" (except for the L brackets) and then use plenty of standoffs to make a more rigid robot. Make the drive axles double as standoffs, put some in between the wheels... just add some and you'll have a lot less problems. Don't forget cross bracing between the two sides.

I would see if you could make your chassis shorter. Why all that height? That's just more material and more weight.

Are you able to cold roll flanges into sheet metal (do you have a brake)? If so, they will dramatically improve your resistance to bending.
