Taiwan is located in the subtropical region. For temperate plants、 the temperature in winter is too high、 which make them not to germinate smoothly. Therefore、 its necessary for them to spray pesticide. However、 its very troublesome to prune and spray pesticide at the same time. And here comes our motivation to shorten the two processes mentioned above.
The traditional process of spraying pesticide is to prune buds with a scissor in the right hand; meanwhile、 to immerse the branch in the soaked sponge in a small bottle held by the left hand. However、 its very dangerous for the farmers to repeatedly do the work with their heads and hands raised、 which may even lead to accidental death.
The earliest device consists of a fixed board、 pressurized device of the shower-cream bottle、 and a pressurized bucket. The chemical will be sent to the cross-sections of the branches by the pressure from the pressurized bucket. However、 the defects are that the water pressure cannot be controlled and that it cannot be operated smoothly.
To improve the defects、 the installation of motors、 motor sensors、 mobile power bank、 and control valves are required、 which may make it easier to operate.
