The DexHand021 Pro represents China’s first fully biomimetic, five-fingered dexterous hand with an integrated wrist-hand structure and dual-tendon drive. It features four core innovations: 22-DoF biomimetic design, dual-tendon drive system, wrist-hand integrated control, and integrated edge AI compute. This enables multi-scale, continuously differentiable dynamic control and omnidirectional 3D-space manipulation. The innovative dual-tendon drive system, capable of bidirectional actuation, works in synergy with a full-palm sensing system to execute high-speed, high-precision, fine-grained, human-like finger movements and explosive grasping tasks. The unique wrist-hand integrated control technology expands the operational workspace by approximately 30%. Supported by built-in edge AI compute, it achieves millisecond-level real-time decision-making, accurately replicating the natural range of motion of the human wrist. By integrating real-time dual-tendon tension feedback with high-resolution tactile sensing, the hand maintains stable operation even under multi-dimensional motion and external disturbances. It excels in motion precision, anti-interference capability, and dynamic speed regulation, standing as the five-fingered dexterous hand that most closely mimics human hand movement.
