Alex, are you able to supply a pic (or even a basic drawing) of what your crusher is going to look like just to make it easier to visualise each type of self-righter?

I found it an interesting task coming up with a self-righter for my crusher due to the shape of it. I bought an electric window mechanism which had a kind of swing-arm action that I was planning on mounting inside the rear half of the claw so that when the bot was on its side, the arm could turn and push it back up again. Only problem now is that it doesnt fit, plus Ive now altered the design of it a lot and it will require a new style of self-righter
