Cable-driven parallel mechanism has attracted wide attention in recent years due to its large workspace and fast response speed. At present, most of the cable-driven parallel mechanisms control the length of each cable through the winch on the fixed support, so as to control the movement of the end moving platform, but the anchor point on the winch is fixed. The design of this fixed anchor greatly limits the motion space of the moving platform. In this paper, a reconfigurable fixed anchor cable parallel mechanism (R-CDPR) is proposed to solve this problem. This paper focuses on explaining how to realize the two ways of reconstructing the fixed anchor through the mechanical design method. The two methods are applied to a traditional 8-cable-driven CDPR, and the three-dimensional modeling of the whole device is completed by using SolidWorks software. In addition, the motion of R-CDPR is simulated by Matlab-Simulink and other simulation software.
