More than 100 leading robotics experts are urging the United Nations to take action in order to prevent the development of "killer robots".
In a letter to the organisation, artificial intelligence (AI) leaders, including billionaire Elon Musk, warn of "a third revolution in warfare".
The letter says "lethal autonomous" technology is a "Pandora's box", adding that time is of the essence.
