But strength and precision aren't enough; robots also need to feel. Human hands are wrapped in sensitive skin that gives us instant feedback: too tight, too loose, slipping, stuck. Rigid metal fingers have none of this. That's why researchers are developing soft robot hands covered in flexible, sensor-rich artificial skin that can detect pressure, texture, and contact in real time. For assembly tasks where a fraction of a millimetre matters, this sense of touch transforms a robot from a blunt instrument into something genuinely delicate and genuinely useful.
