Why does Digit 5 sit down when a person walks past? It shows exactly where Digit 5 is on the safety roadmap: step 1, cooperative safety. Agility distinguishes between two distinct levels: 🚶‍♂️ Step 1: Cooperative safety (Digit 5): Sharing the same open workspace without cages, working around humans without physical contact. 🤝 Step 2: Collaborative safety (future goal): Direct, simultaneous interaction—like handing tools back and forth. Instead of freezing upright—where a 284 lb biped risks tipping—Digit 5 uses 360° vision to detect a close approach, sits down safely to yield the space, and resumes walking once the person has cleared the area. No plexiglass cages needed, just safe spatial coexistence.
