Chinese scientists create advanced robotic hand

Chinese researchers have developed a flexible robot called BioflexBot, which outperforms the human hand in certain motor and grasping tests. The robot relies on a simple design based on a helical spring and a casing that guides its movement, functioning with a straightforward pneumatic system capable of executing a variety of motions such as rotation, suspension, and grasping using only two air inputs. It can extend and contract up to 3.5 times the range of a human hand and handle objects up to 13 times larger than those that similar systems can manage. The design focuses on the hand's function rather than its appearance, making it less complex and more affordable. The robot successfully performs delicate tasks such as handling injection needles and transferring liquids, making it useful in laboratories and medical and industrial applications that require high precision. Although the human hand features advanced sensory capabilities and fine neural control, BioflexBot demonstrates a specific mechanical ability to represent a wide range of movements and handle various objects, excelling in some tasks beyond the human hand. The study's results represent an important step toward simpler and more efficient robotic designs that could accelerate the development of robots operating across diverse fields.
