KCFRC: Kinematic Collision-Aware Foothold Reachability Criteria for Legged Locomotion
Lei Ye, Haibo Gao, Huaiguang Yang +6
Legged robots face significant challenges in navigating complex environments, as they require precise real-time decisions for foothold selection and contact planning. While existin…
PegasusFlow: Parallel Rolling-Denoising Score Sampling for Robot Diffusion Planner Flow Matching
Lei Ye, Haibo Gao, Peng Xu +7
Diffusion models offer powerful generative capabilities for robot trajectory planning, yet their practical deployment on robots is hindered by a critical bottleneck: a reliance on…
VLM-Empowered Multi-Mode System for Efficient and Safe Planetary Navigation
Sinuo Cheng, Ruyi Zhou, Wenhao Feng +4
The increasingly complex and diverse planetary exploration environment requires more adaptable and flexible rover navigation strategy. In this study, we propose a VLM-empowered mul…
Whole-Body Constrained Learning for Legged Locomotion via Hierarchical Optimization
Haoyu Wang, Ruyi Zhou, Liang Ding +5
Reinforcement learning (RL) has demonstrated impressive performance in legged locomotion over various challenging environments. However, due to the sim-to-real gap and lack of expl…
