how much does the special projector cost?@newsoftxmc

The projector should cost ~600USD (from Ti website), and 1000-1200 USD on digikey.
That's sadly a NOGO for my involvement in this construction (Too expensive for personnal use and hard to deal with my company fablab)
Anyway the projector is roughly the price of 10-15 bots.

For use of this special projector (4.000Hz display), I think having understand this allows binary encoding every pixel on the surface. On 600x680 resolution, each dot should be blinking its own binary position code. I guess it could ensure a positioning rate ~400-100Hz.

I will try to spend more time clearly understanding positioning coding.

Owners have said it will be cheap if replace with IR-type scanner /projector.
But that will be another gist :)
From my recent thinks on this project, desired situation is: no central projector/scanner, each robot can locate themselves.
Why? That will make the robots can explore freely,no limit,no boundary.
Isn't attractive?
