The master’s thesis deals with the construction design of the gripping jaws of the machining center manipulator, taking into account the customer´s requirements. The introduction of thesis is a brief introduction to automation, including an overview of available robots. Subsequently, the types of grippers available on the market are described. In the following part of the thesis, the current state of use in practice is discussed. In the practical part, five solution options were proposed. Consequently, the work deals with the construction design of a particular concept selected on the basis of the two-point evaluation method. Subsequently, FEM analysis of the most stressed parts of the gripping machine is performed. The purpose of the work is to design an automatic device for handling workpieces that differ in size and weight.
