The team from Vinclu in Japan have developed a super cool 'virtual home robot' called Gatebox. Part assistant, part companion - Gatebox's central character Azuma Hikari is the star of the show.
What I think is incredible about this project is that Gatebox is not trying to compete with other home service robots, that help with shopping (i.e reordering washing powder) they are targeting a far greater problem, people living alone, and loneliness.
So why not have another friend? :)
