"Autonomous Military Robotics: Risk, Ethics, and Design" By Ethics + Emerging Sciences Group at California Polytechnic State University, San Luis Obispo, sponsored by the Department of the Navy
In this report, we will present: the presumptive case for the use of
autonomous military robotics; the need to address risk and ethics in
the field; the current and predicted state of military robotics;
programming approaches as well as relevant ethical theories and considerations
(including the Laws of War, Rules of Engagement); a framework for technology
risk assessment; ethical and social issues, both near- and far-term;
and recommendations for future work.
and "Malak" by Peter Watts
Inside the mind of an autonomous drone with a conscience, but as usual with Watts it all goes wrong.
