Abstract: In view of the difficult problem of insect pest control in orchard, an intelligent spraying robot suitable for romote control operation was desigened. After testing the machine field maximum climbing angle of 33 degrees,the operating speed of up to 5.65 km/h,the mechanical arm level adjustment angle can reach 180 degrees,spraying height can reach 1~3 m,wireless video transmission and control in no circumstances can block 200 m transmission distance,a small amount of occlusion under the environment of 100 m. This machine provides a new method for the prevention and control of orchard diseases and insect pests.

Key words: orchard spraying, key component, design
