Photos: Killer robots at Ceatec

Ifbot, also from Business Design Laboratory, is a helper robot. It talks and responds to voices. When you say "konichiwa," it responds in kind. Company representatives said Ifbot is made for use as an aid to elderly and homebound people, and as an educational device for children. It can make emergency calls and act as a recording device.
