they are worth it early on when your struggling to build the skylab as fast as possible....not the uri ones..the credit ones.....
ideally..you should build the lab in stages...so each early stage is one level ahead of the next..that way..you shouldnt run out of ingredients for each next stage..if your sending rock to sell or boost lazers n stuff..you'll need the little extra boost the bots supply..
you wont need to use many if your doing things right...and it doesnt cost too many creds....the uri ones just speed it up a little bit more...but if your doing things right in the first place..you wont need the uri ones...
i usually set them going when i start a new account to get things shuffling along at the early stages..
there is no way to speed up production of sep...once its at level 20..thats it..as fast as it will go...takes about 2 days to fill up...
