Latest Patents

Liu is named on 1 patent, titled “Fusion System of Mechanical Arm and Dexterous Hand, and Motion Control Method.” The invention combines a four-degree-of-freedom mechanical arm, a two-degree-of-freedom wrist, and a dexterous hand. Together, the components form a six-degree-of-freedom system.

The patent describes treating the combined system as a six-axis serial robotic arm for motion control. Forward kinematics calculates the hand’s end position and orientation from joint angles, while an inverse-kinematics numerical method determines joint angles for reaching a target pose. The system’s redundant degrees of freedom allow the five-finger hand to rotate without requiring large movements of the mechanical arm.

Career Highlights

Liu’s disclosed invention addresses the coordination of robotic-arm and hand movements. By integrating wrist motion and kinematic control, the system is designed to support dexterous manipulation while limiting the arm’s range of motion.

Collaborations

Zhihong Chen and Si Zeng are identified as Liu’s coworkers. Their names are also associated with the patent’s collaborative technical work.

Conclusion

Shuxuan Liu’s patent presents an integrated approach to robotic manipulation, combining a mechanical arm, an articulated wrist, and a dexterous hand in a coordinated control system.
