About this paper
Peiran Xu, Jiaqi Zheng, Yadong Mu
The RoboAgent framework enhances embodied task planning by implementing a capability-driven pipeline within a single Vision-Language Model, decomposing complex tasks into five distinct vision-language capabilities. It achieved state-of-the-art performance on the EB-ALFRED and ALFWorld benchmarks, demonstrating improved task success rates and more interpretable decision-making.
Key insights
- Explicitly defining and supervising specialized vision-language capabilities within a VLM facilitates a more transparent and controllable reasoning process for embodied agents.
- Decomposing complex embodied tasks into a sequence of simpler, capability-driven vision-language problems allows VLMs to leverage their understanding and reasoning abilities more effectively.
- A progressive multi-stage training strategy, incorporating expert, model-generated, and augmented data with targeted reinforcement learning, systematically improves a VLM's performance and generalization in structured planning.
