Robotics Expert (Fallout 3)

Robotics Expert is a Fallout 3 Perk.
 * Requirements: Level 12, Science 50%
 * Ranks: 1
 * Benefit: With the Robotics Expert perk, you do an additional 25% damage to any robot. But, even better, sneaking up on a hostile robot undetected and activating it will put that robot into a permanent shutdown state.

General
Unlisted Benefits: Additional dialog options with certain robots. This includes characters such as Button Gwinnett, President Eden and Cerberus. It also gives you the ability to bypass one of Moira Browns Wasteland Survival Guide quests.

Regardless of what the description states, you can still run up to a robot, enter sneak mode and deactivate it regardless of being detected or not.

Side Effect: Deactivating a robot will award no experience and will prevent the robot from being accepted as a target in V.A.T.S.. A deactivated robot can still take damage and destroying one will give the same experience and loot as normal. Every attack on a deactivated robot while sneaking will register as a sneak attack critical regardless of the player's location or Sneak level. Any weapon will damage a deactivated robot, but destroying a deactivated robot with bare hands and sneak attacks saves ammunition and will not degrade weapons.

Dialog Benefits
Additional dialog options with certain robots. These often bypass speech checks or give humerus results.
