Abstract—The contribution of this paper is two folds – it reviewed current design of bedridden repositioning systems based on parallel mechanism and proposed a novel 3-DOF mechanism based on 2-RPS 1-PRS mechanisms. The methodology adopted to identify the mechanism is based on systematic design process, including functional analysis and benchmarking of all available bedridden repositioning systems, using Pugh’s method. In order to verify the validity of the proposed mechanism, its inverse kinematic characteristics are critically analyzed. The analytic formulae are derived for inverted displacement and then modeled using MATLAB program. The result is verified to be consistent with the calculated ones.
