This is the other achievement that pairs with Promotion for the two alternate endings at the end of Chapter 5. Instead of placing the broken robot in the incinerator, fly up higher and place it on a small receptacle and activate the switch so the security scanner scans it, which will open up the exit up and to your right. This allows you to escape and unlock Escapist.
