This fair booth brings the fascination of mechanical construction closer to children and young people. Via PlayStation 2 controller, visitors control a ball cannon and shoot on a target. According to the number of hits, the prizes are collected from a conveyor belt from three different candy vending machines and delivered to the child. ecause it should be a transportable system, a low weight of the system was required. Therefore numerous plastic parts from igus® were used instead of conventional metal parts: igubal® flange bearings, plain bearings, thrust washers, clip bearings and PRT slewing ring bearings from the iglidur® series, drylin® guide rails as well as xiros® pedestal bearings and polymer ball bearings.
