BookBot: A Robotic Manipulation Benchmark for Voice-Driven Book Recognition and Grasping in Cluttered Environments

Books, as enduring repositories of cultural heritage as well as knowledge, play a fundamental role in human development. Although advances in embodied AI and robotics revolutionize automation in domains, e.g., manufacturing and logistics, robotic book manipulation remains an underexplored frontier. Two primary bottlenecks impede progress: (1) scarcity of fine-grained annotated datasets for benchmarking robotic book manipulation, and (2) lack of unified perception-action frameworks capable of dynamically coupling multi-modal sensing and manipulation in real-world scenarios. To these issues, we present THU-Book, the first open-access benchmark featuring 643 3D scene captures, encompassing 11,298 high-fidelity book instances with rich annotations to support tasks from book recognition and localization to grasping and repositioning. Building upon this foundation, we develop BookBot, a novel voice-interactive book manipulation pipeline to support cross-environmental, multilingual, and multi-categorical book manipulation. First, we utilize Large Language Models (LLMs) to parse and comprehend ambiguity in user instructions. We further propose an instance segmentation module combined with OCR tool to link language to visual instances. Finally, we introduce a PCA-based manipulation policy to refine the robotic grasp pose, utilizing the principal components of the books’ geometry, improving the precision and efficiency of grasping. Experiments conducted on the THU-Book benchmark validate the effectiveness of our BookBot. The dataset is available at https://github.com/wanghq-public/BookBot.
