PRINCIPLES OF SPRAYING OF PESTICIDES:

Sprayers convert a pesticide formulation , often containing a mixture of water ( or another liquid chemical carrier , such as fertilizer ) and chemical , into droplets , which can be large rain- type drops or tiny drops or tiny almost - invisible particles . This conversion is accomplished by forcing the spray mixture through a spray nozzle under pressure . Nowadays the farmers are playing the crucial role by working hard in the agriculture lands and planting the crops for the societies living in different regions for earning their minimum needs. In India the pesticide usage is higher which 70% is whereas the world-wide pesticide usage is 44% only. Air is getting polluted by using these pesticides. This is the major problem in agriculture. For this, a robot is developed to spray the pesticides by its own and it is less harmful to the environment. The project is under wireless sensor network. The application of wireless sensor network agricultural, Bio-medical, Environmental etc. This bot will help the farmers very effectively. This bot will spray the pesticides over entire the crop . This bot can be easily controllable. The bot sprinkles the pesticides covering all plants in the farm. This will use in pest control and disease prevention application forms. By using this bot, the time and work of the farmer will be reduced.

Harvesting bot

Introduction :

A harvesting robot is designed to pick fruits automatically under certain environmental conditions. Research on harvesting-robot-based machine vision is still in its infancy. With the development of artificial intelligence technology, 3D spatial information about the target can be obtained and processed.

Working:

The collecting arm of a harvesting robot needs to be mobile enough to reach into foliage, and delicate enough to handle fruit without damaging it. Most robots do this with pincers or claws, and researchers are working to build robots that can mimic the soft dexterity of the human hand. The bot using led and a camera that can recognize colour and distance with the help of computer vision sweper decides if the fruit is ripe if it is the bot uses a razor cut off the stem and place it to the container which is attached to the bot.
