Dynamic Legged Ball Manipulation on Rugged Terrains With Hierarchical Reinforcement Learning

RA-L 2026

Achieving reliable object manipulation while traversing complex terrains is the missing link between agile quadruped locomotion and practical autonomy. Specifically, using traditional end-to-end reinforcement learning (RL) for dynamic ball manipulation in rugged environments presents two key challen

MCP Security Bench (MSB): Benchmarking Attacks Against Model Context Protocol in LLM Agents

ICLR 2026poster

The Model Context Protocol (MCP) standardizes how large language model (LLM) agents discover, describe, and call external tools. While MCP unlocks broad interoperability, it also enlarges the attack surface by making tools first-class, composable objects with natural-language metadata, and standardi…
