not really. the whole bot as seen from the side is a triangle.
the idea was to make it invertible, so no matter on what side it drives, and having a wedge as "backside", and the spinner on the (almost) vertical side of the triangle.
Now the diameter of the spinner is fixed by how high the bot is at half of that as distance to the bot.
For an angle of 45° for the wedge i got (17+r)*tan(22,5)=h
with 17cm the length of the rest of the bot including a small safety gap to the spinner, r being the radius of the spinner and h being the height of the bot at the point where the axis is.
The left side of that equation would be the overall length from tip of the wedge to the axis of the spinner.
Not included is some extra height since the wheels would of course make everything a bit higher than just the chassis. Only ways to change this would be:
use smaller internal parts (i couldn't find any) or making a sharper wedge (and the wedge-part is getting ridiculous long then, with a lot very flat, unused space on the inside, making weight for the armor much higher).
So to make the spinner scrape the ground no matter on which side i drive, i would need a value for r that gives me an x a little less than 2r would be.
(hope this works...)

you should be able to see a view from one side.
the small square are gearboxes/drive motors as seen from the side (wheels would be there), the bigger rectangle are both ESCs (brushed for drive, brushless for weapon) and the battery seen from the side. then the back wall (1cm HDPE), and those lines are the outlines to where the chassis would go, depending on weapon size and position.
Maybe this could make it a bit clearer if anybody is still interested in the overall concept.
Well... seems to be a concept not working (this way) anyway.
Will likely have to swap battery/escs and drive train, put everything in a box shape and go with a normal beater or something like that. Actually, that will only make me lose the wedge and the unique look. And i'll need a new name.
But will be way easier to build and drive, and likely more effective, too.
Maybe i can come back to that when i am more experienced, technology is advanced, and i could possibly have a few ideas how i could actually pull that off. Oh, and maybe even enough money to just try it and another bot to enter if it fails^^
Still, learned a lot just from this thread, will try to put it into use when planning this new bot (won't call it another version, too much change for that). Maybe it'll be something completely different.
