China unveils robot hand that extends 3.5 times farther than human hand

China has unveiled a robot prototype that can outperform human hand in certain movements, extending and contracting 3.5 times farther than a human hand. Called BioflexBot, the robot combines a coiled spring, a flexible outer shell and compressed air to enable dexterous movements. It can pinch, rotate, hook and grasp objects, with potential applications in laboratories and confined environments.
