Abstract: The study proposes the process and methods of real-time analyzing the relationship between each joint angle and the terminal position of the mechanical arm. Firstly, each section’s club length data of manipulator with degree of freedom is used as the basis, with a 3D modeling tool being used to model and lead the model into the MATLAB environment. Then, a movement solution analysis and inverse solution analysis of the manipulator will be conducted and be used to calculate and solve the problem. On this basis, Robotics Toolbox under the MATLAB software environment is used to conduct simulated analysis to the robot's real-time movement condition and the kinetic characteristic of displacement, velocity, acceleration and the end of the manipulator are obtained. This method can intuitively analyze the motor process of the manipulator and it provides great support to the movement and operation control of robots.
