CoFL-S: Spatially Queryable Sector Flow Fields for Local Language-Conditioned Navigation
Haokun Liu, Zhaoqi Ma, Yicheng Chen +5
Vision-Language Navigation has increasingly emphasized high-level instruction reasoning, memory, global map construction, and instruction decomposition, while the low-level action…
CoFL: Continuous Flow Fields for Language-Conditioned Navigation
Haokun Liu, Zhaoqi Ma, Yicheng Chen +5
Existing language-conditioned navigation systems typically rely on modular pipelines or trajectory generators, but the latter use each scene--instruction annotation mainly to super…
Learning Agile and Robust Omnidirectional Aerial Motion on Overactuated Tiltable-Quadrotors
Wentao Zhang, Zhaoqi Ma, Jinjie Li +6
Tilt-rotor aerial robots enable omnidirectional maneuvering through thrust vectoring, but introduce significant control challenges due to the strong coupling between joint and roto…
Hierarchical Language Models for Semantic Navigation and Manipulation in an Aerial-Ground Robotic System
Haokun Liu, Zhaoqi Ma, Yunong Li +4
Heterogeneous multirobot systems show great potential in complex tasks requiring coordinated hybrid cooperation. However, existing methods that rely on static or task-specific mode…
