Does the robot's 6-cost development counters count towards Galactic Federation?
No.  


  Add the robot's VP chips and tableau VPs, scoring each 6-cost development card or counter as 6 or 9 VPs, depending on the selected game difficulty.


Galactic Federation, as well as any other such development card, will always count for 6 or 9 VPs.  Don't try to count based on the contents of the tableau.
