Action Agent: Agentic Video Generation Meets Flow-Constrained Diffusion
Jeffrin Sam, Nguyen Khang, Yara Mahmoud +2
We present Action Agent, a two-stage framework that unifies agentic navigation video generation with flow-constrained diffusion control for multi-embodiment robot navigation. In St…
ReFineVLA: Multimodal Reasoning-Aware Generalist Robotic Policies via Teacher-Guided Fine-Tuning
Tuan Van Vo, Tan Q. Nguyen, Khang Nguyen +5
Vision-Language-Action (VLA) models have gained much attention from the research community thanks to their strength in translating multimodal observations with linguistic instructi…
XFlowMP: Task-Conditioned Motion Fields for Generative Robot Planning with Schrodinger Bridges
Khang Nguyen, Minh Nhat Vu
Generative robotic motion planning requires not only the synthesis of smooth and collision-free trajectories but also feasibility across diverse tasks and dynamic constraints. Prio…
DoublyAware: Dual Planning and Policy Awareness for Temporal Difference Learning in Humanoid Locomotion
Khang Nguyen, An T. Le, Jan Peters +1
Achieving robust robot learning for humanoid locomotion is a fundamental challenge in model-based reinforcement learning (MBRL), where environmental stochasticity and randomness ca…
ReFineVLA: Reasoning-Aware Teacher-Guided Transfer Fine-Tuning
Tuan Van Vo, Tan Quang Nguyen, Khang Minh Nguyen +2
Vision-Language-Action (VLA) models have gained much attention from the research community thanks to their strength in translating multimodal observations with linguistic instructi…
TD-GRPC: Temporal Difference Learning with Group Relative Policy Constraint for Humanoid Locomotion
Khang Nguyen, Khai Nguyen, An T. Le +4
Robot learning in high-dimensional control settings, such as humanoid locomotion, presents persistent challenges for reinforcement learning (RL) algorithms due to unstable dynamics…
