This from the Daily Mail:

Jules has 34 internal motors covered with flexible rubber (‘Frubber’) skin, which was commissioned from roboticist David Hanson in the US for BRL.

It was originally programmed to act out a series of movements – as can be seen in the video – where ‘Jules’ talks about ‘destroying Wales’.

The technology works using ten stock human emotions – such as happiness, sadness, concern etc – that the team ‘taught’ Jules via programming.

The software then maps what it sees to Jules’s face to combine expressions instantly to mimic those being shown by a human subject.
