Sharp release 1800 RoBoHon droid that is a walking robot as well as phone

R2-D2 may have played a part in defeating the Empire in Star Wars, but it didn't have a phone and its dance skills were terrible. However, soon you could call your friends on your very own droid that's small enough to fit in a backpack. Sharp showed off the prototype earlier this year - but today confirmed it will start selling it in Japan - for 1800. The gadget is an alternative to a conventional smartphone and has its own SIM card to make calls without having to be linked to a mainstream device. Sharp's robot contains a SIM card so it can make calls.
