Why Robot Arms Cant Operate a Doorknob
Lucas and Luna tackle a deceptively simple task that stumps even the most advanced robotic arms: opening a door. They dig into the physics of compliant motion, the role of force-torque sensors, and why a task humans master by age two remains a benchmark for dexterity. Drawing on examples from the 2026 DARPA Subterranean Challenge and a 2023 study from the University of California, Berkeley, they explain why the real challenge isn't just gripping—it's the subtle coordination of force, friction, and alignment. If you've ever watched a robot fumble a door handle and wondered why…
