Cables Configuration Analysis for a planar CDPR, based on the Lowest Kinematic Energy for a Rotation Movement

In the field of robotics, energy consumption is a very important factor that must be considered. Plenty of research focuses on optimizing the systems design in order to maximize energy efficiency. In cable driven parallel robots, the energy required for picking up or releasing is directly related to the geometric position of the links between the cables and the final effector. This article evaluates the configuration of a cable driven parallel robot with three degrees of freedom, and a rectangular final effector. For this reason the kinematics are analyzed with a Jacobian matrix using Screws theory considering different linkage points. With the kinetic energy known it is possible to find a proper location guarantying the lowest energy consumption. All calculations are done in a MATLAB and the results are corroborated with the Adams View 2017.2 simulation software.
