ASTRIL-MPC: Autonomous Traversal Framework of Articulated Tracked Robots with Language-Guided Neural-Kinematic MPC

Zhenfeng Gan, Yanbo Chen, Lirong Che +2

In urban search and rescue, articulated tracked robots (ATRs) must traverse structured but contact-rich environments such as stairwells and cluttered building interiors. Reliable a…

CoCoBench: A Cooperative Coordination Benchmark for Embodied Multi-Agent Task Planning

Yang Chen, Ye-Xin Xie, Lirong Che +8

Agent systems powered by multimodal large language models (MLLMs) have advanced rapidly in recent years, yet existing embodied-agent benchmarks still lack fine-grained diagnostics…

The Quality-Utility Paradox: Why High-Reward Data Impairs Small Model Mathematical Reasoning

Haolong Qian, Xianliang Yang, Yinuo ma +6

Knowledge distillation from powerful reasoning models is widely used to improve Small Language Models (SLMs) on mathematical reasoning, often assuming that traces with higher rewar…

DemoEvolve: Overcoming Sparse Feedback in Agentic Harness Evolution with Demonstrations

Lirong Che, Yuzhe yang, Peiwen lin +3

Agent harness evolution improves frozen language-model agents by modifying the executable structures around them. We study this paradigm as a form of sample-efficient fast adaptati…

PhotoAgent: A Robotic Photographer with Spatial and Aesthetic Understanding

Lirong Che, Zhenfeng Gan, Yanbo Chen +2

Embodied agents for creative tasks like photography must bridge the semantic gap between high-level language commands and geometric control. We introduce PhotoAgent, an agent that…

MANSION: Multi-floor lANguage-to-3D Scene generatIOn for loNg-horizon tasks

Lirong Che, Shuo Wen, Shan Huang +5

Real-world robotic tasks are long-horizon and often span multiple floors, demanding rich spatial reasoning. However, existing embodied benchmarks are largely confined to single-flo…
