Dirt-resistant igus linear system displays wins in long jump9-7-2019
Results in athletics can be confusing for the viewer. Whilst in football it is clear when the ball is in the goal, it is not immediately apparent in the long jump whether the jumper has set a new record. Virtual lines help the audience on TV, but are not visible in the stadium. Armin Margreiter therefore devised a new solution for his certified mobile athletics system. The former national coach of the Austrian long jumpers, together with the laser projection expert MediaLas, developed a system that projects the furthest jump distance in the sand. It consists of three laser diodes, which are aimed at the pit and produce a visible line even in direct sunlight. To move the laser diodes, the developers needed a drive unit that can move to positions over a range of 3 to 12 metres. The system should also be easy to transport. Therefore, the decision was made to use a sliding, lubrication-free and maintenance-free drylin linear system from igus on which the laser moves. It consists of lightweight high-performance plastic and aluminium components that are very easy to transport and set up. |
