Experience life with an endearing, big-eyed robot with lifelike features — including artificial body temperature and affectionate personality — that is being marketed as an alternative to pet ownership in Japan.

At an event for families that kicked off Tuesday, several Lovot robots developed by Tokyo-based venture Groove X Inc. frolicked with visitors to the EQ House facility in Tokyo's Roppongi district.

Upon entering the exhibition room, one of the 43-cm robots wheeled over to reporters and flapped its arms, beckoning to be held.
