I am Yibo Li (李一博), a master’s student in Software Engineering at Beihang University, advised by Prof. Lu Sheng. I currently work as an embodied AI algorithm intern at AgiBot and previously worked at the Beijing Academy of Artificial Intelligence (BAAI).

My research interests include embodied intelligence, vision-language-action (VLA) models, robotic spatial reasoning, active perception, and long-horizon manipulation. I am particularly interested in how robots build and use visual memory to acquire information, reason in 3D space, and act reliably in real environments.

Publications & Reports

RoboBrain 2.5: Depth in Sight, Time in Mind

Technical Report, arXiv:2601.14352 · 2026

  • Contributed to data and model development for depth-aware 3D spatial reasoning and dense temporal value estimation, improving spatial and temporal modeling in embodied foundation models.

ActiveArena: Benchmarking and Understanding Active Perception in Robotic Manipulation

2026 · First author

Overview: ActiveArena is a unified testbed for studying how robots actively acquire, maintain, and use information during manipulation. It introduces ActiveArena-Sim, 35 tasks across five categories, rich memory annotations, and ID/OOD protocols with disjoint scenes and unseen distractors.

My contribution: Proposed the benchmark and its evaluation protocol; built ActiveArena-Sim and ActiveArena-Bench; developed 13 VLA configurations to analyze memory writing, memory capacity, proprioception, subtask supervision, and high-level planning.

Learning Active Perception and Manipulation via Spatio-temporal Visual Memory

2026 · Co-first author

Overview: ActiveZero formulates active perception as information-driven spatio-temporal memory management. A unified VLA model expands memory through exploration, retrieves relevant evidence for action, and filters memory online for efficient long-horizon interaction.

My contribution: Built the end-to-end active-perception VLA and its memory expansion, retrieval, and filtering mechanisms; contributed to ActiveMem and ActiveBench, including large-scale training data, VQA evaluation, and long-horizon simulated manipulation.

RoboTracer: Mastering Spatial Trace with Reasoning in Vision-Language Models for Robotics

ECCV 2026 · 2025–2026 · Co-first author

Overview: RoboTracer is a 3D-aware vision-language model for spatial tracing, combining universal spatial encoding, metric-aware supervised fine-tuning, and metric-sensitive reinforcement fine-tuning. It introduces TraceSpatial, a 30M-pair dataset, and TraceSpatial-Bench for multi-step metric-grounded reasoning.

My contribution: Contributed to large-scale robot manipulation and spatial reasoning data construction and cleaning across AgiBot, DROID, and RoboTwin; designed the unified pipeline for trajectory extraction, spatial consistency checks, and anomaly filtering.
