Hybrid Impedance-Admittance Control with Multi-Link Aerial Robot for Contact-Rich Surface Sliding Task
Zicheng Luo, Maolin Lei, Jinjie Li +3
Multi-link aerial robots can actively deform their articulated structures during flight, giving them strong potential for aerial manipulation. However, they still face substantial…
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…
Design, Modeling and Direction Control of a Wire-Driven Robotic Fish Based on a 2-DoF Crank-Slider Mechanism
Yita Wang, Chen Chen, Yicheng Chen +5
Robotic fish have attracted growing attention in recent years owing to their biomimetic design and potential applications in environmental monitoring and biological surveys. Among…
Hierarchical Trajectory Planning of Floating-Base Multi-Link Robot for Maneuvering in Confined Environments
Yicheng Chen, Jinjie Li, Haokun Liu +3
Floating-base multi-link robots can change their shape during flight, making them well-suited for applications in confined environments such as autonomous inspection and search and…
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…
