In this paper we present an improved method to compute force distributions for cable-driven parallel robots. We modify the closed-from solution such that the region where a solution is found is extended almost to the theoretical maximum, i.e. the wrench-feasible workspace. At the same time continuity along trajectories as well as real-time efficiency are maintained. The algorithm’s complexity and thus the computational burden scales linearly in the number of redundant cables. Therefore, the algorithm can also be used for highly redundant cable robots. The proposed algorithm is compared to known methods and computational results are presented based on the IPAnema prototype.
