Robots World on Instagram: "🦾 Robotic hands tighten screws faster than humans because their control systems run thousands of times per second. Electric actuators start and stop instantly, while sensors in each fingertip measure force and contact in real time. Vision systems guide the hand in 3D, correcting tiny misalignments before they become errors. Machine learning makes them even better. Robots learn from thousands of assemblies, know exactly how much force to apply, and instantly detect pr
