High strength fibre ropes are facing a strongly increasing interest for rope driven applications. Basic characteristics such as strength are already competitive or even outperforming wire ropes; however other limitations still prevent their full reliable industrial use. One particular application where the advantages of high strength fibre ropes do have an extraordinary important effect on the usability of the application is the use in robot systems with multi-rope kinematics. Basic requirements of these systems are (among others) high accuracy paired with a high efficiency, which means high process velocities as well as high accelerations and decelerations. Many tests have already been conducted to simulate a wide range of load settings. However up to date testing of fibre ropes in high speed usage is still mostly missing. This article describes the state of the art of high strength fibre rope usage in material handling, discusses advantages and disadvantages of these ropes and points out the most important challenges for research and improvement of rope driven robot systems.

高强度纤维绳面临着对绳索驱动的应用的强烈兴趣。强度之类的基本特征已经具有竞争力甚至超过钢丝绳；然而，其他限制仍然阻止其完全可靠的工业用途。高强度纤维绳的优势确实对应用程序的可用性具有非凡的重要作用的一种特殊应用是在具有多绳运动学的机器人系统中使用。这些系统的基本要求（除其他系统外）具有高效率，这意味着高过程速度以及高加速度和减速。已经进行了许多测试，以模拟广泛的负载设置。但是，在高速使用情况下，最新的光纤绳索测试仍然丢失了。本文介绍了物料处理中高强度纤维绳索使用的艺术状况，讨论了这些绳索的优势和缺点，并指出了研究和改进绳索驱动的机器人系统的最重要挑战。
