500 years of robots go on show in London

Why do humans build machines that resemble them - and what does that say about us? A London exhibition opening on Tuesday is surveying 500 years of simple to sophisticated robots to find out. Take a lip-syncing monk from the 16th century or a cartoon-like humanoid avatar that helps children with autism today. They and 100 other robots on display at the Science Museum chart an evolution of machines that fascinate and terrify in equal measure.
"One of the big issues with doing a show like this is people's preconceptions that robots come in, they destroy the world and they enslave us all," lead curator Ben Russell told AFP.
Studying robots is a good way to learn what society was like at any given point, the exhibition argues.
A 16th-century articulated manikin - a little model of a man - allowed its owners to explain and explore the human body.
A monk statue built on behalf of King Philip II of Spain, also from the 16th century, was designed to impress. It is able to pray, walk across a table while moving his lips, and raise a crucifix.
And dating from 1773, a stunning Silver Swan moves with grace thanks to three separate clockwork mechanisms.
Science fiction has fed for more than a century on fears that humans might be overtaken by the machines they create, and the robotisation that is increasingly a part of everyday life still stirs up debate.
A report from the Reform think tank this week predicted 250,000 British public service jobs could be lost to robots over the next 15 years.
In France, a presidential candidate wants to create a "robot tax".
Artificial intelligence (AI) has also divided the scientific community, with renowned physicist Stephen Hawking saying AI could be "either the best, or the worst thing, ever to happen to humanity."
