Product Description
The DexHand021 Pro is the first domestic wrist-hand integrated dual-cable-driven fully bionic five-fingered dexterous hand. It features a 22-degree-of-freedom bionic architecture a dual-cable-driven system wrist-hand coordinated control technology and end-measurement force sensing as its four core innovations enabling multi-scale continuous differentiable dynamic control and omnidirectional three-dimensional space operation. The innovatively added dual-cable-driven forward and reverse drive system combined with the full-palm sensing system can precisely perform high-speed and refined operations similar to human fingers as well as explosive grasping tasks. The unique wrist-hand coordinated control technology expands the operating space by 30% and with built-in AI computing power to support millisecond-level real-time decision-making it can accurately reproduce the natural range of motion of the human wrist. Through real-time feedback of dual-cable tension and linkage with high-resolution tactile sensors it can maintain stable operation under multi-dimensional motion and external force interference. It excels in motion accuracy anti-interference ability and dynamic speed regulation making it the five-fingered dexterous hand closest to the human hand's movement pattern.
Product Specifications
1. Double-rope drive forward and reverse drive: Omnidirectional finger-to-finger three-dimensional space area coverage DexHand021 adopts a single-cable drive design achieving finger flexion through the main power of the motor + worm gear + tendon cable and finger extension through the passive force of the spring and the tension of the motor tendon cable. Different from the design of DexHand021 DexHand021 Pro adopts a dual-cable drive design. Through ingenious structural design it realizes the active control of finger flexion extension and bidirectional lateral swing enhancing the active control ability anti-interference ability stability and passive compliance. It not only improves the dynamic response characteristics and force control accuracy of the finger but also greatly expands the reachable motion space of a single finger. Meanwhile due to the increase in the reachable motion space of a single finger it further enriches the reachable space of the opposition function and improves the dexterity index of DexHand021 Pro. 2. Integrated wrist-hand structure: Wrist degree-of-freedom expansion and wrist-hand coordination technology As the first-generation general-purpose product DexHand021 adopts a design scheme with built-in motors and drivers and no wrist to facilitate adaptation to the interface of the robotic arm. However the wrist also plays a crucial role in the dexterous manipulation function of the human hand. DexHand021 Pro adds a linear push rod design to the wrist enabling the wrist to swing back and forth and left and right thereby enhancing the operating space and dexterity index of the dexterous hand. 3. Global Perception Design: MultiModal Machine Learning perception covers the entire operating domain with Data drive enabling precise control As an important unit for interactive contact tactile sensors are of great value and significance in addressing the data sparsity of dexterous manipulation models. DexHand021 Pro achieves full-range perception of the palm and enhances the perception index of the dexterous hand through a design scheme featuring large-area contact high-resolution fingertip arrays wide range high sensitivity and multi-modal sensing. 4. Integrate edge computing power: Create a new paradigm for dexterous manipulation intelligent agents DexHand021 Pro is equipped with a high-performance edge computing unit enabling millisecond-level real-time decision-making. Its built-in dedicated AI acceleration chip can run deep learning models locally.
