Abstract

The work presented in this paper focus on underwater operation technology, combined with the kinematics structure characteristics of a self-developed 7-function underwater hydraulic manipulator, a method of the manipulator´s inverse kinematics is proposed. Using the combined method, in the case of knowing the manipulator end-effector´s position and attitude, analytic solution of each joint can be solved quickly. This method is combined with the characteristics of Euler method and geometric method, the former three joint angles are achieved through the Euler method, and the last three joint angles are obtained through geometric method. The effectiveness of the method is verified by simulation and experiment on writing word “SIA”.
