Latest Patents

Guo is named on 1 patent: “Fusion System of Mechanical Arm and Dexterous Hand, and Motion Control Method.” The invention combines a four-degree-of-freedom mechanical arm with a dexterous hand wrist and a dexterous hand. The wrist provides two additional degrees of freedom through a single-joint, spatially orthogonal design.

The patent describes treating the combined system as a six-axis serial mechanical arm for motion control. Forward kinematics calculates the wrist’s end position and orientation from joint angles, while an inverse-kinematics numerical method determines joint angles for reaching a target pose. This six-degree-of-freedom arrangement provides redundancy that can help rotate a five-finger dexterous hand without requiring broad movement of the mechanical arm.

Career Highlights

The available information identifies Guo’s work through her patent and her association with the Beijing Institute of Precision Mechatronics and Controls. Her invention addresses robotic dexterity by coordinating arm and wrist movement to position and orient a hand.
