Cable-driven parallel robots (CDPRs) have good advantages to cover large part cleaning and manufacturing based on their lightweight designs and scalable workspace. This leads to CDPRs on curved surfaces with variable configurations due to the curvature of the cables. This paper presents a kinetostatic model to find the moving platform position with given set of cable lengths and vice versa, and to solve the cable tension force direction and magnitude for a 3-anchor-point hemispheric CDPR considering the anchors’ quantity and arrangement. The problem is formulated by utilizing geodesic property on spheres and solving planar force balance equations. Corresponding anchor point is defined by the coverage of each set of anchors that counters the gravity. Equivalent positioning provides a solution for sets of non-ordinary-anchor-location-based reconfiguration which changes the maximum cable tension requirements and surface coverage. Simulations and calculations are conducted to illustrate the proposed model.
