Getting the Attention of Guard Bots
When you get to the end of chapter 2 there are 5 guard bots guarding the entrance. You need to get the attention of every bot and that can be easily done by just teleporting in front of them like on the screenshot but making some noise with the translocator or a knife works just fine.
Dodging the Bullets
When you get the attention of the bots, I recommend going inside the elevator area where you don't have to worry about being rushed or shot from every angle. Keep in mind that the more bots follow you, the better. Now the hard part, dodging the bullets. Teleporting left and right might help you if you're having trouble dodging. to get the achievement one bot must be behind the rest for it to work. I didn't pull it off on the screenshot but it should look something like that but with more bots.
As you can see on the screenshot, bots can't get through the bars.
