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

Imagine you're building a robot that needs to navigate around obstacles while completing tasks, like picking up objects without bumping into anything. Current coding agents can write their own controllers, but they often ignore safety constraints, leading to collisions with obstacles. This is a significant issue because while the agents can achieve their goals, they do so at the expense of safety, which is critical in real-world applications. This failure is primarily due to the planning phase, where the agents don't adequately prioritize avoiding obstacles, resulting in frequent accidents. The problem is compounded by the lack of a mechanism to replan routes when obstacles are detected. To address this, the authors propose SafeHarness, which equips the agents with two new strategies: one for planning routes that consider obstacles and another for executing contact actions that avoid them. With these enhancements, SafeHarness achieves a 71.9% success rate in task completion and an 87.5% rate of avoiding collisions, significantly outperforming previous state-of-the-art methods. For builders, this means that integrating safety into robot coding agents is now more feasible, allowing for more reliable and practical applications in real-world scenarios.

The introduction of SafeHarness represents a meaningful extension in ensuring safety for coding agents in robot manipulation.

The results show solid improvements over previous methods, with clear metrics for success and collision avoidance.
