This study presents a novel cable-driven parallel robot integrated with rigid–flexible coupling and a variable stiffness system, specifically designed to replicate the motion characteristics of the human cervical spine. Kinematic control of the robot is achieved by establishing a functional relationship between its configuration space and actuation space.

This article designs a three-degrees-of-freedom (3-DoF) series-parallel stabilisation platform (SPSP), analyses the platform's degrees of freedom, establishes an error model, and analyses the degree to which each error affects the attitude error of the moving platform when inputting a sine signal, as well as the degree to which each error source affects the attitude error of the moving platform at a certain attitude. 

In this paper, a novel series three-axis stable platform (STSP) is proposed, and its azimuth angle structure, pitch angle structure, roll angle structure, system control scheme, and control strategy are designed. The main function of this stable platform is to isolate the influence of installation carrier movement or external interference and to provide a stable working environment for equipment installed on the stable platform by establishing a stable reference plane.
