What changed

  • Unitree Go1 experiments cover wall traverses and column orbits with contact-based normal estimation.
  • The controller removes commanded pressing motion and averages tool velocity over each gait cycle.

Relevance to constrained-space work

The method addresses maintaining tool contact while walking, relevant to wiping, sanding and contact inspection.
