A sophisticated system for recognizing the arrow trajectory and high-tech cables ensure that the arrow always lands exactly where it was set. If you only throw in the right direction, there are guaranteed maximum scores.
In darts, this is the legendary “180” – i.e. hitting the small triple 20 field in the upper part of the target three times. What is loudly acknowledged and exuberantly celebrated by the traditionally beer-loving audience and the announcers at the meetings of the world elite of this sport, but which hobby players are rarely granted in life, is much easier to achieve with the new system of the Viennese scientists.
This comes from Georg Feiler, Michael Schwegel and Ulrich Knechtelsdorfer from the research team of Andreas Kugi from the Institute for Automation and Control Technology at the TU. The device, presented on Wednesday with a video on the YouTube platform, consists of cameras for image recognition that record the trajectory of the arrow in a few milliseconds and allow the subordinate calculation system to estimate where the gaming device is flying just as quickly. As a result, a newly developed cable pull system directs the target, which is flexibly suspended from the same, to the point of impact in such a way that the arrow lands exactly in the desired field. All of this happens in just around 250 milliseconds.

The system also has disc rotation in the program, which further enhances the surprise effect in the moving image. In the video, among other things, three people alternately step in front of the prepared disc in quick succession in order to throw in the direction of the triple 20 field with varying degrees of precision. All 15 arrows arrive at the target as if by magic – the technology makes it possible.
However, the project is not just a finger exercise for technology freaks: darts are “an excellent application to demonstrate the performance of our newly developed cable robots,” said Kugi in a university broadcast on Wednesday. Such fluid and dynamic movements, including the rotation of the disc, were previously “only possible with a great deal of additional design effort”. In any case, without the complex mathematical analyzes carried out by the researchers, the disc would not be able to get to the desired position so quickly. For Kugi, the advantages of a flexible approach to technical problems can also be derived from the project: “Why throw precisely when you can also position the disc precisely?”, says the scientist.
