Latent Space “Embodiment”: Integrating Physical Simulation and Model Reasoning for Real-World Manipulation

TL;DR: What if we let language models “think” with their (simulated) bodies—can we create a latent space that blends language, vision, and physics to help robots plan and act in the real world?

Research Question: Can we develop a unified latent space that supports embodied reasoning by integrating language, visual perception, and physical simulation, thereby enabling robust planning and manipulation in real-world robotics?

Hypothesis: A well-aligned, multimodal latent space that encodes language, vision, and physical state information will allow models to generalize better to new manipulation tasks and environments, especially under uncertainty or partial observability.

Experiment Plan: Design a multimodal autoencoder or transformer architecture that jointly encodes linguistic instructions, visual observations, and physical simulation data (e.g., object positions, forces). Train on a suite of embodied AI tasks (e.g., language-guided navigation, manipulation in simulated or real environments). Evaluate generalization to novel tasks/environments and robustness to noisy or incomplete inputs. Compare against unimodal or loosely coupled latent space baselines. Analyze internal latent representations for evidence of cross-modal integration and embodied reasoning.
