In order to improve the accuracy of large space motion simulation, this paper presents a new redundant parallel robot with 14 cables. This new configuration is modeled, simulated and analyzed using spring damper system equivalence, non-inertial system analysis, and iterative computation of dynamics. In this paper, using trigonometric functions with Gaussian noise as the target trajectory, the computational simulation gives the length of the cable, the positional tracking error and the velocity tracking error during the trajectory tracking of the new configuration. By comparing the root-mean-square of position error and velocity error, it is verified that the new configuration can significantly improve the accuracy of trajectory tracking compared to the conventional generic configuration.
