Toilet roll shaped robots help in sticky situations

Tiny robots that jump and roll around and are "shaped like toilet rolls" (for what reason we don't know) are at this very moment being developed by the US police and military to spy on suspects in dangerous situations.

Students at the University of Minnesota are developing the robots which measure about four centimetres in diameter and are designed to scout around buildings. They can even jump up stairs to locate a dangerous criminal.
