The performance evaluation of Cable-Driven Parallel Robots in terms of accuracy, repeatability and long term capacities is a key for their industrial deployment. This paper presents and analyses corresponding experimental results for the PACE prototype, a fully-constrained, redundantly restrained, eight cables and six degrees of freedom cabledriven parallel robot. First, a long-term running test is carried out to evaluate the deviation of the moving-platform pose along time of use. A second experiment consists into a full design of experiments to evaluate the effect of some factors specific to this type of robot on its absolute accuracy and repeatability. Experimental results are presented and discussed.
