I found this device when I am just surfing on youtube finding projects for robotics. This project is done by design incubation centre in National University of Singapore (NUS). The project started with a question:

Would I feel the physical presence of my close ones?

While the internet provides a platform for text messaging and video calling, Roly Poly aims to offer I unique and spontaneous mode of communication exclusively between two individuals. One can be in Taiwan while the other can be in Canada and they call feel each other’s presence instantly.

How it works

With a gentle tap on one Roly Poly, it will affect its partner’s Roly Poly to rock the same degree. Likewise, If there is a sudden shake or rattle in one, the other will have a corresponding reaction instantly.
