Addressing Space, Real-Time, and Reliability Challenges in Robotic Hands Development

The bionic dexterous hand is becoming a key growth area in the robotics industry, with significant advancements expected by 2026. Currently, dexterous hands account for 17%-30% of the total material costs of robotic systems, and funding in this sector is projected to exceed 25 billion yuan in the first half of 2026, with annual sales potentially reaching 70,000 units. This shift signifies a departure from mere conceptual discussions to tangible orders and performance realization. The recent World Artificial Intelligence Conference (WAIC) in Shanghai showcased various exhibitors demonstrating high-degree-of-freedom dexterous hands capable of intricate tasks, highlighting the industry's common challenges in precision actuators. Developers face three critical hurdles: achieving 22 degrees of freedom or more for fine movements while integrating miniature motors, sensors, and wiring in a compact palm, all while balancing space constraints, real-time synchronization, and long-term reliability. The solution lies in innovative control chip architecture. National Technology has introduced a 1+4 distributed MCU architecture designed for 22-degree-of-freedom dexterous hands, optimizing performance through layered control. This system utilizes a main control chip and four node chips for individual fingers, enhancing computational power, real-time response, and compact design, thereby addressing the industry's pressing challenges.
