“You grind the gears of the machines and gain a damage bonus against robots.”— Fallout: New Vegas description
The Courier must kill 50 robots for one rank each time, three times.
- Rank 1: +3% damage
- Rank 2: +6% damage
- Rank 3: +10% damage
- This perk stacks with other damage perks such as Lord Death and Robotics Expert.
Although there are 3 ranks for this perk, a bug in the reward script makes it impossible to get the third rank. The same bug also causes the notification to misreport the rank that is given. When rank 1 is given, the notification says that you've been given rank 2, and when rank 2 is given, the notification says that you've been given rank 3. [verified]
