15、n is the problem in the simulation of mechatronic processes in the design and maintenance phase. If we use the augmented virtual reality, we can illustratively simulate selected mechatronics system. In the model case,

16、where the conveyor moved the object, which it subsequently moved from the conveyor into the catapulting unit. Problematic case appears size of the object which was moving on a conveyor. When we inserted a large object,

17、 it can cause collisions and damage to the end effector mounted on a delta robot. This problem is solved on new devices, applications, where we need to reduce the development time of new devices in the prototype stage,

18、 but mainly in existing machines. So it was possible to quickly predict and reconfigure the production line and thus reduce financial costs of shutdown. After creating simulative model of mechatronics system, team can

20、separation of objects was selected delta-robot, driven by Beckhoff software [9]. After separation on the left or right side (depending on the object type) object was inserted into a part which was equipped with a senso
