Robots are to be placed into the homes of people with dementia as part of a pilot on the Western Isles, but it is just one of many uses machines are being put to in Scotland amid a wider debate on robotics.
NHS Western Isles is the first health board in Scotland to try out Giraff.
The 1.5m (4ft 11in) tall, wheeled robots have a TV screen instead of a head.
A relative or carer can call up the Giraff with a computer from any location. Their face will appear on the screen allowing them to chat to the other person.
The operator can also drive the robot around the house to check that medication is being taken and that food is being eaten.
