The work aims to summarize the research and application situation of palletizing robots. Through the comparative analysis on domestic and international development of palletizing robots, the existing problems of palletizing robots were pointed out. As domestic palletizing robots were severely short of core technology and core components, and the industry scale of robots was uneven, the solutions to these problems were proposed. Although there was a certain gap between the technologies of palletizing robots at home and abroad, there was much room for improvement of domestic palletizing robot technology. Driven by the national policy of the "13th Five-year Plan" for the Development Planning of Robot Industry, the domestic robot technology will change rapidly.
