Campaigners against the development of fully autonomous weapons, known as "killer robots", have urged the United Nations to draft a global treaty outlawing their use.
Prof Noel Sharkey, from the International Committee for Robot Arms Control, travelled to Geneva to lobby members of the Convention on Conventional Weapons.
It will vote on Friday on whether it should consider imposing a moratorium on unmanned weaponry.
Prof Sharkey told the BBC's Today programme that the launch of pilotless planes like the US navy's X-47B moved the world a step closer to the deployment of fully autonomous weapons.
It made aviation history in July by successfully landing on a aircraft carrier, without any human involvement.
