Iván Hernández Dalas: BioflexBot robot hand aims to replicate key human hand motions
Humanoid robot developers are trying to replicate the human hand. Source: Adobe Stock Human hands are dexterous, versatile machines. Roboticists have tried to copy the biological structures of the hand for humanoid grippers. This, however, typically results in complex and difficult-to-control structures. Researchers proposed an alternative end-effector solution in a new study published by Wiley in Advanced Science . They created the BioflexBot, a novel robot that mimics and even exceeds core motions of the hand with a simple design. Instead of creating a robotic hand with the intricate anatomy of a human hand, the researchers aimed to capture fundamental hand motions with a coiled spring, constraining shell, and basic pneumatic system, using compressed air to control mechanical action. Optimized for precision and range of mobility, the BioflexBot can pinch, rotate, hook, and grasp with just two pneumatic inputs. “By harnessing structural and physical intelligence, we pursued a si...
