Latest Patents

Zhang 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, a two-degree-of-freedom wrist, and a dexterous hand. It treats the assembly as a six-axis serial robotic arm, using forward kinematics to calculate the hand’s position and orientation from joint angles and inverse kinematics to determine joint angles for reaching a target pose. The design’s redundant degrees of freedom allow the five-finger hand to rotate without requiring large movements of the mechanical arm.
