Automated store for bottles

Dear Engineer,
I would like to build a prototype, from concept to realization with real components.
The idea is to build an automated store of wine bottles.
In the back of the store we have a vertical storage room where wine bottles are stored.
In front of the store the client through a touch screen select the wines.

Our automated machine should pick the bottle of wine from behind and provide it to the customer.
Between the back and the front there is a wall.

Thanks.
