Modern implementations of industrial robots require the use of extensive knowledge and novel concepts. To bring real benefits, robotized processes must be analysed in detail. This paper presents a preliminary study on the analysis of electric energy consumption of an industrial robot in the alternative palletization processes. Firstly, the robotization of manufacturing processes aspect was discussed and advantages of the robotic palletizing process were presented. Secondly, the utilized off-line robot programming environment and a model of the robotic workstation used during the study were described. Conducting analyses based on the alternative arrangement of elements in a pallet layer allowed discussion and the formulation of important conclusions. The research has confirmed the validity of detailed analysis of robotic production processes.
