HazardArena: Evaluating Semantic Safety in Vision-Language-Action Models
Zixing Chen, Yifeng Gao, Li Wang +8
Vision-Language-Action (VLA) models inherit rich world knowledge from vision-language backbones and acquire executable skills from action demonstrations. Yet current evaluations pr…
A Learning-based Adaptive Compliance Method for Symmetric Bi-manual Manipulation
Yuxue Cao, Wenbo Zhao, Shengjie Wang +4
Symmetric bi-manual manipulation is an essential skill in on-orbit operations due to its potent load capacity. Previous works have applied compliant control to maintain the stabili…
A Policy Optimization Method Towards Optimal-time Stability
Shengjie Wang, Fengbo Lan, Xiang Zheng +5
In current model-free reinforcement learning (RL) algorithms, stability criteria based on sampling methods are commonly utilized to guide policy optimization. However, these criter…
Reinforcement Learning with Prior Policy Guidance for Motion Planning of Dual-Arm Free-Floating Space Robot
Yuxue Cao, Shengjie Wang, Xiang Zheng +3
Reinforcement learning methods as a promising technique have achieved superior results in the motion planning of free-floating space robots. However, due to the increase in plannin…
A Learning System for Motion Planning of Free-Float Dual-Arm Space Manipulator towards Non-Cooperative Object
Shengjie Wang, Yuxue Cao, Xiang Zheng +1
Recent years have seen the emergence of non-cooperative objects in space, like failed satellites and space junk. These objects are usually operated or collected by free-float dual-…
