Project Objective:

The objective of our project is to develop an unnamed aerial vehicles (UAV) to overcome the

harmful effects of pesticides on the farmers (while spraying).


Agriculture in India constitutes over 60% of the occupation. It serves to be the backbone of

Indian economy. It is very important to boost the efficiency and productivity of agriculture by simultaneously providing safe cultivation of the farmers. The Indian Agricultural sector is the most vital sector as it amounts to a staggering 18% of India’s Gross Domestic Product (GDP) and also provides employment to 50% of the national human workforce.

Our country depends on agriculture a lot, and has yet to tap into the potential of agriculture, thanks to improper methods of monitoring crops and the irrigation patterns and also the pesticides required to be applied. Operations like spraying of pesticides, sprinkling fertilizers are very tedious. Though spraying of pesticides has become mandatory it also proves to be a harmful procedure for the farmers.

Farmers, especially once they spray pesticides, take too many precautions like wearing appropriate outfits, masks, gloves etc. so, it doesn’t cause any harmful effects on them. Avoiding the pesticides is additionally not completely possible because the required outcome must be met.

So, use of robots in such cases gives the simplest of the solutions for these problems, together with the specified productivity and efficiency. In India, there are over 35 drone start-ups that are working to boost the technological standards and reduce the prices of agricultural drones. This project aims to develop an Unmanned Aerial Vehicle (UAV) for overcoming this problem and also to spray large amounts of pesticides within a smaller interval of your time using a quad-copter.

Project Outcome/Result/Findings:

i. In this project we have designed an agricultural drone for spraying pesticides on the coconut tree.

ii. It will help to reduce human efforts.

iii. This will help in reducing the time required for spraying pesticides.

iv. It minimizes risk of life since humans are not required to climb the tree.

v. The drone is completely operated by the transmitter and receiver within the range of signal.

vi. If we are flying the drone far away, then the drone will not work properly.

By successful implementation of such project affective spraying of pesticides can be


i. The exposure of highly toxic pesticide to humans can be prevented.

ii. This can also be used in places where laborers are hard to find.

iii. One can hasten the pesticide spraying process and cover large areas in a short time.

iv. Encounters with venomous snakes, which can be found regularly in fields can be prevented.

v. As spraying is done from lower altitude, environmental pollution can be reduced.

vi. Apart from spraying pesticides on coconut trees, it can also be used for spraying pesticides/water on other trees/plants.

vii. Also by looking at the current situation this drone can help in sanitizing large areas.

Innovative Approach:

To spray large amount of pesticides within small interval of time using quadcopter on coconut
