Surely any robot built by the U.S. government will be bound by Asimov's three laws of robotics.
</sarcasm>
A code of moral behavior for intelligent robots will be developed. Isaac Asimov’s Three Laws are insufficient (especially for military).
1. A robot will not harm authorized Government personnel but will terminate intruders with extreme prejudice.
2. A robot will obey the orders of authorized personnel except where such orders conflict with the Third Law.
3. A robot will guard its own existence with lethal antipersonnel weaponry, because a robot is bloody expensive.
