Japanese hotel chain sorry that hackers may have watched guests through bedside robots

Japanese hotel chain HIS Group has apologised for ignoring warnings that its in-room robots were hackable to allow pervs to remotely view video footage from the devices.
The Henn na Hotel is staffed by robots: guests can be checked in by humanoid or dinosaur reception bots before proceeding to their room.
Facial recognition tech will let customers into their room and then a bedside robot will assist with other requirements.
The hotel is one of a chain of 10 in Japan which use a variety of robots instead of meat-based staff.
So far the reference is only to Tapia robots at one hotel, although it is not clear if the rest of the chain uses different devices.
