Robotic hand that works without being attached to arm shown at WAIC

Chinese startup BrainCo showcased its latest bionic hand at WAIC 2026, featuring a soft, skin-like finish that closely resembles a natural human hand. The prosthetic uses myoelectric signals from the residual limb, allowing users to move its fingers even when the hand is detached. The hand offers five-finger independent movement with 0.1° control precision.
