Snappy: Take picture of objects and rearrange them again at same position.

It is a device called "snappy". It is a prototype made by a company of Japan: JST, ERATO
It have :-
A Camera
A Photo-Reader
A Robot



Now the process involved is...

First, the user take a picture of objects and now picture act as storage device which have the data of position of objects.
Whenever you want to arrange objects use picture taken by you in "photo-reader" and let the information fetched by the system.
Now a robot will come rearrange all the objects at the same place as shown in the picture.
In my way it is very impressive, especially think about the hard work they had done creating this device.
