Will there ever be an 'ethical robot'?

Will a robot ever be able to make a decision based on ethical principles?

Professor Alan Winfield, from the University of the West of England, will address this question during a symposium in Birmingham.

Speaking on the Today programme, Professor Winfield said: "We need to be developing robotics - artificial intelligence - ethically."

First broadcast on BBC Radio 4's Today programme on Tuesday 2 September.
