A robotic test rigs with vacuum gripper for analysis of the packing process was presented. Two types of vacuum cups were used, Piab BX 52P and Piab F50-2. Based on the research for the packing process of cardboard packages, relations between parameters were determined, i.e. negative pressure, working speed of a robot and weight of packages. It was determined that for the process of packing 0.25 kg packages, a proper negative pressure should be 0.4 bar, whereas for 0.5 and 1 kg packages should be equal to 0.6 bar. The maximum working speed of a robot, which ensured proper execution of the packing process was 80%. Moreover, impact of the distance between packages in the initial location on the course of packing process was analysed. In this case, the best results were obtained with the use of 15 mm distance.
