Manual labour.
There are tape libraries with robots that can take a tape out of a slot, put it in a drive, and then put it back automatically without humans needing to do anything. If you want to move the tapes offsite, there is some manual work to move the tapes from the import/export slot to a container.
A large library like the StorageTek SL8500 can have up to 640 drives, 100'000 tape storage slots, and 2'880 import/export slots.

- jeffbee 3y agoWho actually has those?
- jandrese 3y agoLast time I saw one of those was back when AOL was a big shot ISP. They had to buy high power SGI systems to feed the things because nothing else had the bus bandwidth to support one. I was told that the full rack sized SGI system (Origin 2000) was the cheapest part of the entire rig.

Also, a system like this probably isn't terribly useful, a Cartesian gantry robot would be much faster and way more robust than an articulated arm strapped to a mobile robot platform.
