Hello,
I am plannig to make a project which includes moving objects (puppies) within area of 25m².
I'd like to see each object separately on the external screen as a moving object on the map.
Here's the scheme for the idea:
There would be about 7 moving objects. Do I have to use 7 arduinos or can I make it less?
Where should I start? Should I use wireless modules? is accuracy in centimeters possible?
Appreciate any tips!
Thanks!

Decide what technique you're going to use to detect the position of a tracked object. This is likely to be hard, and the only approach that seems promising to me is using image processing. An Arduino is no help for that.
Making a live version of LavaRand? 8^)
I think your image is a pretty good way to do it by incorporating PeterH's idea. Put different colored "sweaters" on each puppy, and use a webcam to periodically capture an image, use Matlab or some other image processing tool to find the "blobs" of different colors, find the centroid of the blobs and there you go.
ETA: The reason we suggest this is that no one has come up with a good way to track position in small areas, Arduino or not.
Wow, "sweater" makes sense to me! Thanks for the idea! I'm gonna definitely do it this way. It's not random number generator project but connection betweet animals analysis based on the collected data of position and time. Thank you!
Still, I'm curious - if I use bigger area like 100x100m - is it still too difficult to track with physical modules?
You might get by with differential GPS.
