Experts assemble for U.N.-hosted meeting on 'killer robots'

GENEVA – Experts from scores of countries are meeting to discuss ways to define and deal with "killer robots" -- futuristic weapons systems that could conduct war without human intervention. The weeklong gathering that opened Monday is the second at U.N. offices in Geneva this year to focus on such lethal autonomous weapons systems and to explore possibilities for regulating them, among other issues. In theory, fully autonomous, computer-controlled weapons don't exist yet, U.N. officials say. The debate is still in its infancy, and the experts have at times grappled with basic definitions. The United States has argued that it's premature to establish a definition of such systems, much less regulate them.
