Summary

A new survey provides a structured review of safety in long-horizon robotic manipulation, analyzing the fragmented literature across planning, policy design, and runtime execution from an embodied AI perspective. The review organizes existing work by intervention locus, covering planning-time, policy-time, and execution-time safety, and assesses the strength of evidence, distinguishing formal guarantees, statistical support, and empirical safety heuristics. This framework clarifies the roles of capability papers, direct safety mechanisms, and benchmark studies, while exposing areas where safety claims are well-supported versus indirect. Key persistent gaps identified include limited evidence for policy-time safety, weak formal support for contact-rich long-horizon manipulation, immature uncertainty-triggered intervention, and a shortage of manipulation-specific safety benchmarks. The survey concludes by outlining research directions for cross-layer assurance, evaluation design, and safer deployment of long-horizon robotic agents in real-world settings.

Key takeaway

For Robotics Engineers developing long-horizon embodied AI systems, recognize that current safety literature is fragmented and lacks robust evidence in key areas. You should prioritize research into policy-time safety mechanisms and develop stronger formal guarantees for contact-rich manipulation tasks. Focus on creating manipulation-specific safety benchmarks and improving uncertainty-triggered interventions to enhance real-world deployment safety.

Key insights

Safety in long-horizon robotic manipulation requires a cross-layer analysis across planning, policy, and execution to address fragmented literature and persistent gaps.

Principles

• Safety literature is fragmented across planning, policy, and execution.
• Evidence for safety mechanisms varies: formal, statistical, empirical.
• Semantic misgrounding and error propagation accumulate in closed-loop systems.

Method

The survey organizes literature by intervention locus (planning-time, policy-time, execution-time safety) and analyzes evidence strength (formal guarantees, statistical support, empirical safety heuristics).

In practice

• Focus research on policy-time safety evidence.
• Develop benchmarks for manipulation-specific safety.
• Improve uncertainty-triggered intervention mechanisms.

Topics

• Embodied AI
• Robotic Manipulation
• Long-horizon Tasks
