During your second visit to Planet Orxon, you will be playing as Ratchet and not Clank. What you want to do is get the Nanotech Vendor at the very end of the mission (will reach the vendor for the story, so it's not hard to find). Once you get there operate the vendor and buy the premium one for 4,000 bolts (if you collected all boxes in the level you should have this total). Simply buy it and the trophy will unlock shortly afterwards. If you don't want to buy it right now you can always come back to this room later via the shortcut tunnel near your ship.
