Autonomous Weapons Systems and Meaningful Human Control: Ethical and Legal Issues

The review highlights the crucial role played by the robotics research community to start ethical and legal debates about autonomy in weapons systems. A concise overview is provided of the main concerns emerging in those early debates: respect of the laws of war, responsibility ascription issues, violation of the human dignity of potential victims of autonomous weapons systems, and increased risks for global stability. It is pointed out that these various concerns have been jointly taken to support the idea that all weapons systems, including autonomous ones, should remain under meaningful human control (MHC). Main approaches to MHC are described and briefly analyzed. Finally, it is emphasized that the MHC idea looms large on shared control policies to adopt in other ethically and legally sensitive application domains for robotics and artificial intelligence.
