I have started on my next bot and thought my Idea might help a couple of you.
I build a design frame first out of styrophor. It is alot easier to work with than metal or wood. It is also alot cheaper!!!
I was able to change and test all my measurements before I start with the real frame.
Maybe this will help a couple of beginners in the planning. and only cost about 3 euros and a little glue.
