Combat inhibitor

All robots in Fallout 3 have a combat inhibitor located on their back.

Uses
Destroying a robot's Combat Inhibitor will cause it to attack every entity with which it comes into contact. This is not unlike the frenzy that attacking the Giant Ant's or Fire Ant's antennae will cause (though much harder to accomplish, since the Combat Inhibitor is located at the back of the robot's body).Also it appears that robots "personality" are limited by a combat inhibitor as Cerberus will say that he hates ghouls but his inhibitor prevents him from killing them.
