With the rapid development of roboticsdexterous hands<\/strong>As the core component of robot end-effector, its performance directly determines the robot's performance and scope of application in complex tasks. The global dexterous hand industry presentsa hundred flowers bloom, a hundred schools of thought contend (idiom); refers the classical philosophic schools of thought<\/strong>situation, companies continue to exploreDifferent technological routes<\/strong>to achieve higher degrees of freedom, more precise control, and a wider range of application scenarios.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n\n

The current industry definition of dexterous hand freedom existsBigger Misconceptions<\/strong>Some dexterous hands advertise having 20+ joints as having 20+ degrees of freedom, but they don't have a separate set of motor drives for each of those 20+ joints, they may only have 6 motor drives, which is actually6 degrees of freedom, not 20+.<\/strong>. True degrees of freedom should mean that each joint is equipped with an independent drive motor, and the number of degrees of freedom should be equal to the number of drive motors, not simply measured by the number of joints.<\/p>\n\n\n\n

Technical characteristics<\/strong><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

More rigidity and stability:<\/strong>Direct-drive construction reduces intermediate transmission links, reducing wear and tear and failure rates.<\/p>\n\n\n\n

Full closed-loop control:<\/strong>Real-time feedback and precise control, fast response and high precision.<\/p>\n\n\n\n

High precision transmission:<\/strong>The ring-enveloped worm gear transmission allows for extremely high transmission accuracy and ensures the accuracy of the gripping action.<\/p>\n\n\n\n

Highly integrated:<\/strong>Each joint module is highly integrated, compact and easy to maintain.<\/p>\n\n\n\n
