How robots could help verify compliance with nuclear arms agreements

Ensuring that countries abide by future nuclear arms agreements will be a vital task. Inspectors may have to count warheads or confirm the removal of nuclear weapons from geographical areas. Those hotspots could include underground bunkers and require confirmation that no weapons exist in a location at all. Now, researchers at Princeton University and the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have devised an automated way to ensure compliance.
