Hangzhou Aike Automation Co., Ltd.
How powerful is this "mechanical hand" from China? It can easily grasp a needle, and can also stably hold a 30N weight; it can understand human voice commands and complete tasks independently in complex environments; it has also broken the foreign technological monopoly, enabling the high-dexterity dexterous hand to move from the laboratory to the mass production workshop and be widely applied in various industries.
1. Breaking through technical barriers: Two "Super Hands" have emerged, covering all scenarios and demands.
In the field of dexterous hands, "flexibility" and "practicality" have always been major challenges for the industry. Traditional dexterous hands either have few joints and are stiff in movement, making it impossible to perform precise operations; or they have complex structures and high costs, making mass production difficult. After years of research and development, the team has launched two differentiated core products, completely solving this industry pain point.
Performance Champion: 20 joints + 15 degrees of active freedom, fingertip force exceeding 30N
The first high-performance dexterous hand can be described as the "all-round champion in the world of mechanical hands", equipped with 20 joints and 15 active degrees of freedom, far exceeding the industry average. What does this mean? Human fingers usually have 3 joints, and each joint corresponds to 1 degree of freedom. However, this dexterous hand, through the multi-joint collaborative design, can simulate all the movements of human fingers, such as flexion, rotation, and lateral swing, and even perform more precise operations than human fingers.
What is even more astonishing is its "strength" and "fineness". The team has independently developed a rigid tendon transmission system, enabling each finger to generate a dynamic fingertip force of over 30N - this is equivalent to being able to easily grasp a 500ml mineral water bottle and precisely pick up a strand of hair at the same time. The reason for achieving this "combination of hardness and softness" lies in the fact that each active joint is equipped with dual encoders and torque sensors, just like attaching "nerve endings" to the fingers. They can promptly sense the force situation and adjust the force at any time to avoid damaging the item with excessive force or causing it to slip due to insufficient force.
In laboratory tests, this dexterous hand demonstrated astonishing operational capabilities: it could skillfully unscrew bottle caps and pour out liquids; it could precisely screw screws into nuts with an error of no more than 0.1 millimeters; and even play the piano, accurately pressing each key and producing smooth melodies. This high-precision and high-flexibility performance gives it great potential for application in high-end fields such as precision manufacturing, medical surgeries, and aerospace.
2. Lightweight Pioneer: 11 joints + 7 active degrees of freedom, underactuated design balances efficiency and cost
If the high-performance dexterous hand is regarded as the "flagship model", then the other underactuated lightweight dexterous hand is the "value king". It adopts a design of 11 joints + 7 active degrees of freedom. Through underactuation technology, it achieves more complex movements with fewer driving units, thereby reducing the product weight and cost while ensuring the core operational performance.
Underactuated technology is a key innovation in the field of dexterous hands. Traditional dexterous hands require an independent drive unit for each joint, resulting in a complex structure, heavy weight, and high cost. In contrast, underactuated dexterous hands use ingenious mechanical design to enable one drive unit to control multiple joints in coordination, similar to using a single rope to pull multiple pulleys. This simplifies the structure and reduces the weight. This lightweight dexterous hand weighs only 60% of the high-performance model and costs 40% less, yet it can still complete most daily operation tasks such as grasping, transporting, and assembling.
In practical applications, this lightweight and dexterous hand demonstrates remarkable adaptability. In logistics warehouses, it can quickly grasp packages of various shapes and sizes and sort and pack them; in home environments, it can assist the elderly and the disabled in picking up items, opening and closing doors; on industrial production lines, it can precisely grasp components and complete assembly, welding and other processes. Its emergence has enabled the dexterous hand to move from high-end laboratories to the general public's life, significantly expanding the application scope of the dexterous hand.
3. Comprehensive Technology Coverage: All aspects of tendon ropes, direct drive, and linkage mechanisms are covered.
In addition to the two core products, we have also covered all the mainstream technical routes such as tendon ropes, direct drive, and link rods. This means that no matter what the customer's requirements are, they can find the appropriate product.
The tendon cable transmission technology is adept at achieving high flexibility and long-distance transmission, making it suitable for scenarios requiring complex movements; the direct drive technology can provide higher transmission efficiency and control accuracy, making it suitable for applications with high response speed requirements; the linkage transmission technology has the advantages of stable structure and strong durability, making it suitable for scenarios with high-intensity and high-frequency operations. Through in-depth research and development of different technical routes, a complete product matrix has been formed, capable of meeting the needs of various vertical and specialized scenarios such as automotive manufacturing, electronic production, medical rehabilitation, and service robots.
This all-encompassing layout of this technology not only holds an absolute advantage in the market competition, but also promotes the technological progress of the entire dexterous hand industry. By integrating the advantages of different technologies, continuously optimizing product performance and reducing production costs, high-freedom dexterous hands are no longer a "luxury item" exclusive to a few high-end industries, but a "universal tool" that can serve various industries.
II. Intelligent Brain Enhancement: Large Model + Dual-Route Control, Making the Mechanical Hand "Capable of Listening and Thinking"
If the agile mechanical structure is the skeleton and muscles of the "hand", then the intelligent control algorithm is the brain and nerves of the "hand". The key to its stable operation in complex environments lies in its powerful intelligent control system - based on the self-developed "Zhu Zi - Rixin" large model of Harbin Institute of Technology, combined with autonomous navigation, visual recognition and dual-route control strategies, making the mechanical hand not only "flexible" but also "intelligent".
"Typeface - Renewal" Large Model: The "Super Brain" of the Robot
The self-developed "Lifou - Rensheng" large model by Harbin Institute of Technology is the core control center of intelligent control. This large model has been trained with massive data and possesses strong capabilities in voice dialogue, instruction understanding, and task decomposition. It enables the robotic hand to "understand" instructions like a human and "think" about how to complete the task.
In terms of voice interaction, the "Zhu Zi - Rixin" large model supports multi-language and multi-accent recognition, and can accurately understand human natural language instructions. Whether it's a simple instruction like "Pass the documents on the table to me" or a complex instruction like "First, open the computer, then send an email to someone, with the attachment being the document on the desktop", the robotic hand can precisely recognize it and break it down into a series of executable actions.
What makes it even more powerful is its autonomous learning capability. Through reinforcement learning algorithms, the robotic arm can accumulate experience through continuous operations and optimize the action process. For example, when grasping fragile items, it will find the most appropriate grasping force and angle through multiple attempts; when completing complex assembly tasks, it will adjust the action sequence according to the actual situation to improve work efficiency. This autonomous learning ability enables the robotic arm to adapt to different working environments and task requirements, continuously enhancing its performance.
2. Autonomous navigation + Visual recognition: The "eyes" and "feet" of the robotic arm
In addition to a powerful brain, the robot is also equipped with advanced "eyes" and "feet" - a self-navigation system and a visual recognition system.
The autonomous navigation system employs laser radar, ultrasonic sensors and visual SLAM technology to perceive the surrounding environment in real time, construct a three-dimensional map, and plan the optimal movement path. No matter in narrow workshop corridors or chaotic household environments, the robots can flexibly avoid obstacles and accurately reach the designated positions. For instance, in a factory workshop, the robots can autonomously move to different workstations to complete tasks such as grasping and assembly; in a hospital, it can autonomously navigate to the ward to deliver medicine and meals to patients.
The visual recognition system employs high-definition cameras and AI image recognition algorithms, enabling it to quickly identify the shape, size, color, and position of objects. Whether it is a stationary item or a moving object, it can accurately capture them. For instance, in the logistics sorting scenario, the visual system can quickly identify the delivery number and destination on the package, guiding the mechanical hand for classification; in industrial production, it can precisely identify the installation position of components to ensure assembly accuracy.
The combination of autonomous navigation and visual recognition systems enables robots to possess strong environmental adaptability and autonomous operation capabilities. They no longer require real-time human control and can independently complete complex task processes.
3. Dual-line control strategy: Ensuring stable operation
To ensure the stable movement of the robot in complex environments, the team adopted a dual-track parallel strategy combining model predictive control with full-body control and reinforcement learning.
Model predictive control is an advanced control algorithm that can, based on the robot's dynamic model and environmental information, predict the motion state over a certain period in the future and plan the control strategy in advance to ensure the smooth and precise movements of the robot. Whole-body control focuses on the coordinated movement of the entire robot, allowing the robotic arm, body, mobile chassis, and other components to work together to avoid local action conflicts and improve the stability and efficiency of the movement.
Reinforcement learning enables robots to autonomously optimize control parameters through continuous trial and error and a reward mechanism. For instance, when faced with uncertain environmental disturbances, the reinforcement learning algorithm allows the robot to quickly adjust its control strategy and maintain stable operation. This dual-line parallel control strategy not only ensures the efficient operation of the robot in regular scenarios but also enables it to handle various unexpected situations in complex environments, achieving industry-leading stability in robot operation.
In actual tests, the robots employing this control strategy were able to move smoothly on uneven ground, quickly adjust their postures upon collision, and efficiently switch actions when multitasking simultaneously. They demonstrated remarkable robustness and adaptability.
