Angled Chassis
 

Our team is considering using 8" wheels in the front and 4" wheels in the back to improve our approach angle when traversing the defenses. I don't see anywhere in the rules where this would be illegal as long as the bumpers were of legal height. Does anybody see this differently.

Sounds about right. This does bring up the question about bumper angle to the ground though; It says in the rules that "BUMPERS do not have to be parallel to the floor" so you might be ok unless I am interpreting that wrong.
Past years have required parallelism/perpendicularism IIRC.

Those years were long ago...

As long as the bumper is entirely in the Bumper Zone, you should be good.

Re: Angled Chassis
 

The only thing you gotta consider is the circumference of each wheel. One will have a faster linear speed than the other, so make sure you account for this with your mechanics and programming.

And either a skid plate or zero protrusions on that underbelly in the rear you may be dragging sometimes. Just so you don't get hung up on things. A stuck robot isn't a scoring robot.
