Abstract

This thesis describes the design and development of a robot for spraying pesticides on vegetable plantations. This project aims to develop a robotic system that can spray pesticides on crops efficiently and precisely, thereby reducing the need for manual labour and increasing the efficiency of pesticide application. The robot's primary controller is a Raspberry Pi, equipped with several sensors and a pesticide dispensing system. The literature review examines extant pesticide spraying robots in agriculture and highlights their deficiencies, highlighting the need for an optimized solution. The methodology section describes the overall system architecture and justifies the selection of particular hardware components. Design considerations for the pesticide sprinkling mechanism and the creation of control algorithms and software implementation are described. Integrating sensors for environmental perception and the communication system between the robot and a central control centre is also addressed. The segment on system design and implementation discusses the robot's mechanical design and construction and the mechanism for spraying pesticides. The software architecture, implementation particulars and sensor and actuator integration are provided. Calibration and testing procedures are in place to ensure precise and reliable performance. The robot's precision, efficiency, and coverage performance are assessed and compared to existing solutions or standards. The results are interpreted and discussed in the discussion section, which evaluates the robot's effectiveness in the environment of a vegetable farm, as well as its feasibility, dependability and practicability. The designed automaton has the potential to enhance crop protection practices, reduce manual labour and optimize pesticide consumption, which will ultimately benefit the agricultural industry. This thesis is to observe the performance of the robot regarding the movement of wheels and the performance of pesticide spraying application build in the robot. Speed of robot, distance of pesticide distribution, time taken to empty tank, flow rate of pesticide distribution and coverage of pesticide on plant are the parameters to observe the pesticide spraying application.
