OopsieVerse: A Safety Benchmark with Damage-Aware Simulation for Robot Manipulation
Arnav Balaji, Arpit Bahety, Sriniket Ambatipudi +3
While robotic manipulation capabilities have advanced rapidly, physical safety remains a major barrier to deploying household robots: task success is insufficient if the robot dama…
Learning Causal Structure Distributions for Robust Planning
Alejandro Murillo-Gonzalez, Junhong Xu, Lantao Liu
Structural causal models describe how the components of a robotic system interact. They provide both structural and functional information about the relationships that are present…
ADEPT: Adaptive Diffusion Environment for Policy Transfer Sim-to-Real
Youwei Yu, Junhong Xu, Lantao Liu
Model-free reinforcement learning has emerged as a powerful method for developing robust robot control policies capable of navigating through complex and unstructured environments.…
Towards Efficient MPPI Trajectory Generation with Unscented Guidance: U-MPPI Control Strategy
Ihab S. Mohamed, Junhong Xu, Gaurav S Sukhatme +1
The classical Model Predictive Path Integral (MPPI) control framework, while effective in many applications, lacks reliable safety features due to its reliance on a risk-neutral tr…
Adaptive Diffusion Terrain Generator for Autonomous Uneven Terrain Navigation
Youwei Yu, Junhong Xu, Lantao Liu
Model-free reinforcement learning has emerged as a powerful method for developing robust robot control policies capable of navigating through complex and unstructured terrains. The…
