From Jay Price … Bookbot: Books flowing into new NCSU library's robotic stacks:
One of four automated book delivery system bookBots moves down a 50-foot high, 125-foot long corridor fetching items requested through a virtual browse interface at the James B. Hunt Jr. Library at N.C. State's Centennial Campus in Raleigh on Friday, October 5, 2012. Over 2 million barcoded items are sorted by size and stored in barcoded bins where they can be retrieved through a robotic delivery system.
Each of the four robots has two work stations where its human co-workers can pull books from the bins and put others back in for reshelving.
It takes no more than 60 seconds for one of the robots to retrieve a bin from anywhere in the system, and after the library opens, the goal will be to have a book pulled and placed at one of the designated pickup areas within five minutes
