Fast Humanoid Loco-Manipulation via Flow Matching

Overview

A course project for MIT 6.4210 (Robotic Manipulation) comparing DDPM and Flow Matching for humanoid whole-body control via trajectory synthesis.

Key Results

  • Flow Matching achieves 820 vs. 280 survival steps at 5 neural function evaluations (NFE), dramatically outperforming DDPM at low compute budgets
  • Zero-shot loco-manipulation from walking-only training data via test-time classifier guidance — no manipulation demonstrations needed
  • Demonstrates that FM’s straight-path interpolation is fundamentally better suited for fast trajectory generation than DDPM’s curved diffusion paths
