A Simple Minimum Cable-Tension Algorithm for a 2-DOF Planar Cable-Driven Robot Driven by 4 Cables

In this study, we propose an optimum non-iterative algorithm for the minimum cable tension solution of two degree-of-freedom cable-driven robots. The problem is specifically defined for a cable-driven robot with one end-effector connected to four motors by four cables. A two-cable algorithm and a three-cable algorithm are presented with examples, then the optimal two-cable and three-cable solutions are proven for the absolute value norm and Euclidean norm.
