What are the names of the Portal 2 co-op robots

Yes, the progress is automatically saved and synced to the Steam Cloud individually - so when you next join a co-op game it will have stored which levels you have completed. This also means that your progress is shared across any computer you play Portal 2 on.

It's worth noting that progress is never saved during a test chamber though, only upon successful completion.

You will be able to pick which level to start at next time you start the game - if you go to the specific chapter you want to play and use the buttons until you've selected the level you want, then go into the assembly machine as usual.

All the facts can be found in the subtitles file at \steamapps\common\portal 2\portal2\resource\subtitles_english.txt (or _czech, _danish...). Open it up and search for bits of what you remember, e.g. "dental".
