Project Summary

UAVs are armed with the sensors and cameras for crop observing and aerosols for pesticide spewing.A new good strategy came into practice i.e. a mounted spraying mechanism on UAV for spraying applications. The incorporation of UAV with mounted mechanism provides better platform for pest management and vector control system. The efficiency of mounted spraying mechanism enhances using PWM controller. Crop cultivating has been commercially increasing since last few years. In order to maintain an agriculture field it requires an enormous manpower which is directly related to the cost required for the maintenance of an agriculture field.

Project Objectives

1.A low-cost teleoperated drone for pesticide spraying on fruits and crops is being developed and tested

2.    An android application for teleportation of drone has been developed

Project Implementation Method

Keeping in mind the various consideration parameters like the total weight of the spray mounted system, supporting frame design, total payload capacity, fluid tank design, motors selection, batteries, flight controller, propellers, transmitter and receiver; the complete design was calculated. Development of the system and pre-testing work out has been carried out at EME Center of Innovation & Entrepreneurship – (ICE2).

Gazebo Simulation

      Before executing the UAV project we need to perform the simulation in some virtual world. It is a need create a simulation environment where realistic tests can be performed using open source autopilot, achieved by simulation in gazebo

Framework

     Our framework is an integration of ROS, Gazebo and Pixhawk’s autopilot PX4. ROS is a software package which works as a middleman for the transportation of sensor and control via “topics” through “messages” connecting “publishers” and “subscribers” through “nodes”. Gazebo is one of them. it is an open source, highly fiddle and a fine grained control virtual environment for robotics simulations. Gazebo provides this ability to simulate any possible robotic mechanism in complex indoor as well as outdoor environments.

Geometry

    We modeled the different parts our drone using “SolidWorks”, a CAD design software and
saved them as .stl mesh files. The reason for that is Gazebo only support .stl, .dae file
extension if we want to import a model from outside. Later we assembled those mesh files in Gazebo and defined necessary revolute joints for propeller's angular velocity and fixed joints to connect the spraying mechanism with the base of the drone.

Drone Assembly & Testing

Once the disassembled drone components were procured through official channels we set about studying the official documentation there after we proceeded to assemble and test our drone. We assembled each subpart and tested it thoroughly as to ensure it was done so appropriately. After the complete assembly we once again subjected to a thorough inspection. After we were satisfied with the construction undertaken by us we performed a flight test, which was successful.

integration of Spraying system with drone

    Sprinkling mechanism comprises sprinkling system itself and the controller. In general, the sprinkling mechanism is connected to the UAV lower area and the pesticides is sprinkled downward through the nozzle which is connected beneath the pesticide tank. Sprinkling system consists of nozzles and a tank containing fertilizer or pesticide. Nozzles are excited through the controller. The flow of pesticide is pressurized through the pressure pump.

Benefits of the Project

1. spraying through drone is beneficial as it consumes less spray mateial and water 

2. No threat is imposed to human health due to spray chemical

3. Spraying is achieved in a mcuh less time

4.The cost is lower. Save pesticide cost and labor cost greatly. The spraying of pesticide by drone is usually based on leasing, which is much lower than the cost of labor

5. The rotor of agricultural drone produces a huge downward rotation force, which promotes the pesticide droplets to penetrate the crop from top to bottom, which is conducive to the pesticide droplets evenly scattered in all parts of the plant, so that the spraying is accurate

Technical Details of Final Deliverable

•Medium (7-11 Kg) payload lifting drone

 the project inclued the procurement of a medium payload lifting drone

•Light weight spraying system

inttegration of a light weight spraying mechanism for effecient spraying

•Drone tele-operation using android app

Missions can be used to easily automate flight. There are many different mission types that offer different product behavior. Some missions can be uploaded to and managed by the aircraft, while other missions are managed from the mobile device.

      Missions run from the mobile device can offer more complex or customizable behavior, however if the wireless link between remote controller and aircraft is lost then they can be interrupted. In comparison, missions run from the aircraft will be less customizable and be limited by aircraft memory, but be able to continue when there is a loss in the wireless link.
