Hare and Hedgehog

The two transport robots Hare and Hedgehog drive in the library

Until 2019 the branch library of natural sciences was equipped with a driverless transport system and two associated transport robots called "Hare" and "Hedgehog". A transport system of this kind was unique in European libraries and is normally only used in industry.

With the help of this system, book transports from and to various transfer stations could be carried out independently and autonomously by library staff. Only the destination information in the form of a barcode, which is automatically read by the transport robots, had to be entered by an employee. Everything else, such as opening doors and operating the lift, could be done by "Hare" and "Hedgehog" completely independently.

Using reflectors and a laser on the device, the two transport robots oriented themselves along fixed paths through the entire library.

Since 2019, the two have been in well-deserved retirement and can only be visited on special occasions.
