Need advice on what to buy for my project

Hi all!

I want to build a robot that would automate picture taking of coins.

The structure is built out of Legos to facilitate and I would need some motors/servos to capture all the details. I also saw PTZ camera that could remove this need. Not sure what is better.
PTZ Cam could be : ArduCam PTZ Lens and Controller
While I target ElecFreaks motor/servo for their Lego compatibility

I can’t be certain of the best camera for the project. Either a PTZ to remove servo needs or a fixed one that I would move around programatically. It must take very detailled pictures since details are very small and take whole coin as well. What camera should I use?

I guess I would also need LEDs for lightning. Again, I look into Electrofreaks material.

Then I need a microcontroller. I have some experience with micro:bit programming. But I think it may be a lot for it to control (3-4 motor/servo, a camera, some LEDs…) What do you think? Should I rather go with a Pi or even maybe connect it directly to a PC?

I’d take any advice you guys can give me at this point as I don’t have much experience.

Thanks a lot!
