I have a problem I cannot find the answer on the Internet. I want to achieve this figure in `(a)` in the attached image (of course I made this manually and has a lot of mistakes): Two misaligned circles, and inside them a bunch of circles that have the same distance from the outer circle to the inner circle. My first problem is that I don't know how to align objects between the two lines of the outer and inner circle (and I don't mean manually or measuring with the ruler). Perhaps moving the centers of the big circles (see `(b)` )to the edge? I suppose I have to create the black elements of `(c)` and then have a bend somehow to create the blue ones (?). But I am completely lost.

If I can borrow joojaa's image it would look something like this:
