To operationalize this concept, we first develop the Embodied Web Agents task environments, a unified simulation platform that integrates realistic 3D environments with interactive web interfaces.

4. Error Analysis
We analyze failure patterns in GPT-4o cooking tasks to understand the primary challenges in embodied web agent integration.
Error Type Distribution in Cooking Tasks
66.6%
Cross-Domain Errors
Failures at the intersection where physical and digital domains meet. Agents become trapped in single-domain cycles.
14.6%
Embodied Errors
Issues with physical world perception, planning, and action execution in the embodied environment.
8.0%
Web Errors
Problems with web interface interaction, information retrieval, and digital reasoning tasks.
10.8%
Other Errors
Miscellaneous failures including system errors, timeout issues, and unexpected behaviors.
Critical Bottleneck Identified: The most prevalent failure pattern involves agents becoming trapped in single-domain cycles, with cross-domain errors overwhelmingly dominating the failure landscape.
π Key Insights
Our analysis reveals that the primary challenges in embodied web agents lie not in isolated capabilities, but in their integration across domains.
1
Domain Integration Challenge: Cross-domain errors (66.6%) far exceed individual domain errors, indicating that seamless integration between physical and digital realms remains the primary technical challenge.
2
Single-Domain Traps: Agents frequently become stuck in repetitive cycles within one domain, failing to effectively transition between embodied and web interactions when required.
3
Relative Domain Performance: While both embodied (14.6%) and web (8.0%) errors occur, their individual rates are significantly lower than cross-domain failures, suggesting competency in isolated tasks.
π Performance Implications
This error distribution confirms that the critical bottleneck emerges at the intersection where physical and digital domains meet, rather than within individual domain capabilities. Future research should prioritize developing more sophisticated cross-domain coordination mechanisms and transition strategies for embodied web agents.
