Talons are lightweight robots used to detonate potential bombs in many countries, including Iraq and Afghanistan.
Talon is controlled by nearby remote control. The model can drive at high speeds and have arms that place small detonators used to disarm suspected bombs.
Sword replaces Talon's arm with a machine gun.
The inventors point out that a human is always in control of Sword, but that may soon change. The Pentagon Office of Naval Research issued a request in August asking for research on more complex machinery that could make its own decisions.
