A talking robot which chats to elderly people, reminding them to take their medication and stay active, has been launched in London.

Elli.Q, which is one of the most advanced social companion robots in the world, has been designed to convey emotion through different speech tones, lights and body language to be as engaging as possible.

The little robot suggests activities such as reading, going for a walk, playing games to keep mentally active or phoning friends and family.
