Coding Agents with an Obstacle-Aware Harness for Safe Robot Manipulation

Bingxin Xu, Yuzhang Shang, Zhen Dong et al.1 min readarXivSep 17, 2026

Key Takeaway for Students

Coding agents have emerged as a promising paradigm for robot manipulation: a language model writes the robot controller as a program, and agents built in this way now operate robots without robot-specific training.Whether this paradigm is also safe, however, has not been asked. We evaluate coding agent under a safety constraint, where each task pairs a manipulation goal with an

This paper highlights a critical safety gap in current coding agents for robotics, where goal completion overrides safety constraints. For ML engineers, understanding how to integrate and prioritize safety in AI-driven control systems is crucial for deploying reliable and ethical robotic solutions.

Interview questions

Describe how you would design a planning module for a coding agent to ensure safety constraints are prioritized over task completion, even when the LLM's generated code doesn't explicitly enforce it.
What are the challenges in evaluating the safety of an LLM-driven robotic agent, and what metrics would you propose to quantify 'obstacle avoidance' success?
Design a system architecture for a robot manipulation platform that uses a coding agent but includes a separate, hardened safety layer. How would these components interact, and what failure modes would you anticipate and mitigate?
