Final resting place of the robot

If you walk north-northeast starting at the entrance of Propulsion you will see a monument and a Prometheus Spark on top of a high platform next to a fan activated by a pressure plate. In order to switch the fan walk around the monument and you will see a small, mouse-like robot. Interact with it and it will slowly walk towards the plate and it will stop on top of it, activating the fan which you can use to jump and get the spark.
