Fall 2024 GRASP Seminar: Yunzhu Li, Columbia University, “Foundation Models for Robotic Manipulation: Opportunities and Challenges”

*This seminar will be held in-person in Levine 307 as well as virtually via Zoom.

ABSTRACT

Foundation models, such as GPT-4 Vision, have marked significant achievements in the fields of natural language and vision, demonstrating exceptional abilities to adapt to new tasks and scenarios. However, physical interaction—such as cooking, cleaning, or caregiving—remains a frontier where foundation models and robotic systems have yet to achieve the desired level of adaptability and generalization. In this talk, I will discuss the opportunities for incorporating foundation models into classic robotic pipelines to endow robots with capabilities beyond those achievable with traditional robotic tools. The talk will focus on three key improvements in (1) task specification, (2) low-level, and (3) high-level scene modeling. The central idea behind this research is to translate the commonsense knowledge embedded in foundation models into structural priors that can be integrated into robot learning systems. This approach leverages the strengths of different modules (e.g., VLM for task interpretation and constrained optimization for motion planning), achieving the best of both worlds. I will demonstrate how such integration enables robots to interpret instructions provided in free-form natural language, and how foundation models can be augmented with additional memory mechanisms, such as an action-conditioned scene graph, to handle a wide range of real-world manipulation tasks. Toward the end of the talk, I will discuss the limitations of the current foundation models, challenges that still lie ahead, and potential avenues to address these challenges.
