86 J. Maierhofer et al. need for any human interaction. Further work could include some optimization calculations to find the best impact settings regarding different quality functions. The simulation shows that multiple parameter sets may exist which lead qualitatively to the same impact force. Therefore one has to choose between these sets with regard to robustness of the impact and other outer constraints. Another future aspect will be the further development of the hardware, to increase usability and minimize the footprint of the AMimpact in reaching even more points in very complex geometries.
