Pesticide Spraying Autonomous Quadcopter
Project Area of Specialization RoboticsProject SummaryThe aim of this project is to design the drone that is unmanned aerial vehicle (UAV) for agricultural purpose for spraying pesticides . In Pakistan agriculture is the huge sector . But now a days its facing a lot of problems due to non-using of modern techniques . Also other problems are chemical contact with pesticides and danger from insects and animals . The drone can be useful for spraying pesticides and crop protection . this can be done by the single person standing at a safe distance and by controlling the UAV . This helps the farmer in reducing the time taken and also provide the safety to the farmer . this drone system mainly works on the principle of thrust . the drone contains four arms and each arm four motors are attached along with the propeller which provides the lifting effect . The movement of the drone is controlled by the radio controller and the speed of the drone is also controlled by it . The proposed work in the research paper is for the use of the unmanned aerial vehicle for spraying the pesticides in agriculture sector .
Project ObjectivesUp to the date, the pesticides are spraying by the conventional methods by using the handpumps on the back or by manually by throwing using hands. So this methods are very time consuming and dangerous for the health issues . Because there is continuously contact of the human with the pesticides and this is very dangerous things for health. And also sometimes it is not possible to reach to the each and every crop sapling for being pesticide. So this may lead to spreading a disease which can be observed due to insufficient supply of the pesticides and this may cause to the decrease in the yield.
Project Implementation MethodThe development of quadcopter is being carried as follows;
Phase 1: Initialization, literatur review, choosing BLDC motor of specific RPM, Battery, ESCs, Propellers, and frame, calculating thrust, distance, flight time, weight.
Phase 2: Balancing the quadcopter, installing GPS, sensors and making a GUI for the control of quadcopter.
Phase 3: Using Google Map for Autonomous control, object detection and pesticide spray.
Phase 4: Fizalinzing the project with final deliverables; hardware and final project report.
Benefits of the ProjectThe main use and advantage of this project is that drone will be helpful for farmers for spraying pesticides and crop protection while being controlled by a person operating from a safe position .Currently the drone we are developing is for spraying pesticides only but there are a lot of future scope for this concept which are:
- Crop surveillance for monitoring the farm from a safe position
- Plant Disease Diagnotic
The final deliverables of the quadcopter being developed are:
- Autonomous Spraying Quadcopter
- Obstract Detection
- Autonomous Control (Following Google Map)
- Graphic user interface (GUI) to control the Quadcopter
