英文摘要：

Precision spraying robot is based on timely access to information on crop diseases, the disease position is measured accurately, and take the variable spraying according to the difference, to achieve on-demand application. The key technologies of precision spraying robot include targeted crop disease recognition technology, precision applying pesticide technology and independent walking technology, which is based on independent walking, disease detection and precision spraying is the core. According to the current progress, the paper introduces the technology of classification and application of precision spraying robot, and summarizes the limitations of existing technology and the scientific issues to be solved, finally the future development direction of precision spraying robot is put forward.
