After many people in the library read the book, they randomly placed them in other places. This phenomenon has plagued librarians. Recently, researchers at the A*STAR Institute of Information and Communication have designed an AuRoSS (Automatic Machine Bookshelf Scanning) robot that can automatically shuttle through the library at night and report lost or misplaced books by scanning RFID tags on the book. .
The next morning, the library's human staff could easily find the misplaced books and put them back where they were by looking at the results of the report.
This wheeled robot uses lasers and ultrasonic sensors to guide it to work. Researcher Renjun Li said: "We decided to let these robots themselves detect the surface of the bookshelf and use it as a reference to plan the path."
With the help of the robot arm, the robot maintains the optimal label scanning distance by adjusting the RFID antenna: too far will lose the signal, and too close will hit the bookshelf.
At present, researchers have tested AuRoSS robots in various libraries in Singapore with an accuracy rate of 99%. Researchers say that in addition to RFID sensors, the system can be integrated with cameras, Bluetooth and Wi-Fi. Warehouses, retail stores or medical technology, aerospace and automotive industries.
