Need advice on what to buy for my project

Let's Make Robots Beginners
1

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!

@Pascal_PAN Has this project progressed at all? If not, as you mentioned, it really is a software intensive project. You’ll need to device the procedure you want the follow: how does each coin get to the place they need to be photographed, what stops the process to then have the camera photograph each coin and save it somewhere, then move it to a bin and into the next one. A microcontroller can control a conveyor belt etc., but won’t do much for capturing and saving the image(s) in a file on your computer.
