Robotics Expert/Fallout 3

Robotics Expert is a perk in Fallout 3.

Effects
A flat +25% damage bonus against all robotic enemies. In sneak mode, the player can shut robots down. Shutting a robot down will award 10 experience and prevent targeting it in V.A.T.S. The robot can then be destroyed as normal for the usual experience and loot rewards, and since it's inactive, entering stealth will guarantee sneak attack critical hits.

The following robots are affected:
 * Automated turrets
 * Chimeras
 * Eyebots
 * Guardian drones
 * Protectrons
 * Robobrains
 * Masterbrain
 * Sentry bots
 * Mister Handies
 * Mister Gutsies
 * Support drones

Additional interactions
The perk also unlocks a number of special interactions:
 * Roosevelt Academy: Reprogramming Dean Dewey to gain passage.
 * Underworld: Allows for shutting down Cerberus' combat inhibitor, making it go berserk.
 * National Archives: Forcing Button Gwinnett to shut down and clearing the way for the Declaration of Independence.
 * Nuka-Cola Plant: Reprogram Milo to recognize the Lone Wanderer as an employee.
 * Wasteland Survival Guide: Allows for skipping the trip to the RobCo facility without losing any points for the good version of the guide.
 * Mobile base crawler: Allows for reprogramming the crawler mainframe to turn the security robots on the Enclave and ignore the player, and also unlocks a bonus dialogue option with Stiggs mentioning that.

Bugs

 * Sentry bots may glitch and become stuck in their shutdown animation.
 * Due to the way the detection system works, it's possible for alerted robots to be shutdown, which may seem like a bug instead of a feature.
 * When shutting sentry bots down, a Talk prompt may appear. It does nothing, however.
