Automated Book Return & Sorting System at Sanya Library — Libiao Robotics

Project Overview

Sanya Library, located in Sanya, Hainan Province, China, has deployed Libiao Robotics' automated book return and sorting system to transform one of the most labor-intensive recurring tasks in library operations: the sorting and routing of returned books. Published in December 2025, the case study showcases Libiao's application of its AGV-based sorting technology in a public cultural institution context — a deployment that extends the company's platform beyond its established commercial logistics base into the public services sector.

The core value proposition is elegantly simple: patrons drop off their returned books and leave immediately, while the automated system handles everything that happens next. The downstream sorting — categorizing books by subject area, floor, or shelving zone and routing them to the correct destination — is performed entirely by Libiao's robots without librarian intervention. For Sanya Library, this means staff time previously consumed by repetitive manual sorting is freed for patron-facing services, collection management, and other higher-value activities.

This deployment is notable within the Libiao Robotics portfolio as one of the few publicly documented applications of the company's sorting technology outside of commercial logistics. It demonstrates the platform's adaptability to non-warehouse environments and positions Libiao as a technology provider capable of serving public sector clients alongside its established commercial customer base in e-commerce, postal, retail, and 3PL sectors.

Technical Solution

Libiao AGV Sorting Platform for Library Operations

The Libiao Robotics system deployed at Sanya Library applies the company's AGV (Automated Guided Vehicle) and robot sorting platform to the specific workflow of library book return processing. While the commercial logistics deployments of Libiao's technology focus on parcel sorting, e-commerce fulfillment, and retail distribution, the underlying sorting logic — receive an item, identify its destination category, route it to the correct sort location — is directly applicable to library operations.

In the library context, the "destination category" is defined by the book's classification — typically a combination of subject category (Dewey Decimal or Chinese Library Classification system), floor, and shelving zone within the library's physical layout. The sorting control software maps each returned book's classification to a physical sort destination, and the AGV fleet executes the routing accordingly.

Key Features

Patron Drop-Off and Immediate Departure The primary patron-facing benefit is the elimination of waiting at the return point. The automated system processes returns continuously and immediately, enabling patrons to deposit books and proceed to their next activity without delay. This frictionless return experience is explicitly highlighted in Libiao's case study framing: "So you can drop off your reads and head to your next story quicker."

Elimination of Manual Librarian Sorting The system removes the manual sorting workload from library staff entirely. Once a book is deposited at the return station, the automated system handles all subsequent steps — identification, categorization, routing, and delivery to the sort destination — without requiring any librarian intervention. This is the core operational benefit for Sanya Library as an institution.

AGV-Based Sorting Technology The deployment uses Libiao's AGV robot platform — the same underlying technology applied in the company's commercial logistics deployments, adapted for the library environment. The AGV platform provides reliable, consistent sorting performance in a public facility setting, with the robot fleet managed by Libiao's fleet control software to coordinate routing and avoid conflicts.

Smart Logistics for Public Cultural Institutions The Sanya Library deployment demonstrates that smart logistics automation is not limited to commercial warehouses and distribution centers. Public cultural institutions — libraries, archives, museums — manage physical collections that require ongoing sorting, routing, and location management, and can benefit from the same automation principles that drive efficiency in commercial logistics. Libiao's ability to adapt its platform to this context expands the addressable market for its technology beyond traditional logistics buyers.

Results & Benefits

For Library Patrons:

• Faster, friction-free book return — deposit and leave immediately
• No queuing at return counters during peak periods
• Improved overall library visit experience

For Library Staff:

• Repetitive manual sorting workload eliminated
• Staff time freed for patron-facing services, collection management, and programming
• Reduced physical demands associated with manual book handling and trolley pushing
• More consistent and reliable book processing regardless of return volume fluctuations

For Sanya Library as an Institution:

• Improved operational efficiency in the return and sorting workflow
• More reliable shelving turnaround — returned books reach their shelving zones faster
• Reduced dependence on staffing levels for return processing throughput
• Demonstration of smart technology adoption in a public cultural institution context

Challenges & Solutions

The central challenge of this deployment is translating commercial logistics automation technology into a public library context. The physical environment, operational workflow, and user population of a public library differ significantly from a commercial warehouse: the "items" are books rather than parcels or totes, the "customers" are library patrons rather than order recipients, and the "sort destinations" are shelving zones rather than dispatch lanes or carrier chutes.

Libiao's solution addresses this translation challenge by applying the same core sorting logic — receive, identify, route — to the library-specific workflow, with the sorting destinations and classification logic configured for Sanya Library's collection structure and physical layout. The AGV platform's adaptability to different physical environments enables deployment in a library setting without requiring fundamental changes to the underlying technology.

The public-facing nature of the deployment also introduces considerations that are less prominent in commercial logistics: the system must operate safely and reliably in an environment shared with library patrons of all ages, including children. The AGV platform's navigation and safety systems must be appropriate for a public space context, operating predictably and avoiding conflict with patron movement throughout the library.
