Description:SPRAYING AGRICULTURAL PESTICIDE ROBOT

Field of the Invention
This invention falls under agricultural automation and robotics disciplines and technology of pesticide application. More particularly, it presents an autonomous robotic system that can traverse farmlands and spray pesticides which helps in minimizing the health dangers that come with manual spraying of pesticides. The robot uses a variety of advanced techniques, including planning the most suitable route, navigating within the field, and using multi-sensor systems to enhance the effectiveness and safety as well as reduce the manual workforce involved in the work.
Objectives of the Invention
This robotic pesticide sprayer has a few fundamental targets. These are:

Less Use of Pesticides: This robot assists in minimizing the pesticide not only by optimizing spray patterns but also by targeting areas where it is actually needed. It is not only cost effective but also reduces the level of environmental pollution erosively triggered by excessive pesticides.

Elimination of Measurable Health Risks: In the current technical setting, the nature of the conventions on farmers' spray jobs involves great exposure to poisonous chemicals which pose dangers like skin cancer as well as respiratory system disorders among others. The innovation aims at ne eliminating this risk by allowing the users to deploy the sprayer at a safe distance by the use of a smartphone application.

Reduction of Manual Labor Intensity: The aim of the robot is to ensure that the users remain with minimal manual labor during pesticide application. By using remote control and ever assisting autonomous navigational features, it saves the farmers a lot of time to engage in other activities, and helping to resolve the issue of labor shortage witnessed in agriculture.

Reliability and accuracy of pesticide application: In order to ensure the efficacy and efficiency of the robot, route planning and control systems for the sprays are incorporated into the system to ensure that there is high precision in application. Compensation of path errors and real-time spray pattern adjustments help the robot to always apply pesticides evenly and avoid wastage.
Background of the Invention
Agriculture remains one of the key sectors of the economy in India and brings in a good amount of revenue to the country as well as sustains a very large chunk of its population. However, owing to the increased supply of food, the farmers' dependency on the use of pesticides to increase crop production is also on the rise. Sadly, the dominant approach to pesticide application - hand spraying - causes serious health hazards by putting farmers at risk of being exposed to poisonous chemicals.

Most farmers are exposed to pesticides and suffer from skin and respiratory diseases including cancer. The excessive reliance on pesticides has environmental impacts as well because pesticides can enter the food chain through the food supply. In addition, the tedious nature of manually applying pesticide also reduces the recruitment potential in agriculture.

Taking into account these circumstances, this project was carried out with the view of developing a robotic system for the automated spraying of pesticides. The goal is to come up with a solution that is affordable, reduces health and labor input to the minimum level possible, and ultimately, makes agricultural activities safer and more sustainable.
Description of Prior Art
Various robotic solutions for agricultural purposes have been developed, but they often lack the comprehensive functionality offered by this invention. Prior art includes agricultural robots designed for tasks like plowing and seeding. However, these devices usually require significant manual control and are limited in terms of navigation, safety, and spraying precision.

Existing pesticide sprayers also have limitations, including the inability to navigate complex field layouts autonomously or adapt to varying environmental conditions. Additionally, previous systems often lack user-friendly controls, making them challenging for farmers to operate without specialized training. This invention addresses these gaps by incorporating a simple Android-based control system, multi-sensor capabilities for environmental monitoring, and real-time adjustment mechanisms to enhance precision and safety in pesticide application.

In relation to the present invention, it concerns with improvements in a hand-held pump spray for spraying liquids on plants or crops such as herbicides, pesticides, fragrances, and any other sprayable liquid such as aromatherapy oils. [WO2006152259A1]

The invention applies C4 grass plants that reduce nitrogen fertilizer inputs for maximizing biomass and growth kinetics. Such grasses are used with biological soils serving as sources of C4 nitrogen-fixing bacteria for sustainable agricultural techniques. [WO2018221875A1]

The current invention is in the realm of vector biological control creations. More specifically, it pertains to a technique and a strategy of efficient pest eradication utilizing 5G technology which entails the following comprising, multiple units of self-walking medicine spraying terminals; A specific terminal intended for scanning and patrolling assignments within a targeted region and being able to communicate relevant coordinates of its location and the targeted zone to the control center upon detection of such region, a detection terminal; A control center having the capability of receiving location coordinates from the endpoints and inputs of the location information into a given quantity of pre-trained neural networks and generating a time period of working hours which complies with the heating commands issued at the given time. It also has the capability of dispatching location information to the self-sufficient serving medicine spraying machine with necessary heating commands. Upon moving to the specified part of the room the serving medicine machine will be commanded to spray the medicine for the stipulated time period; and lastly, it also has the capability of the control center issuing specific time duration while providing location coordinates and specific targets within self walking spray terminal units that are not necessarily within the specified areas of focused repeated commands. This application has and reduces the manpower and consumes, improves the intelligent degree that the media biological was prevented and is controlled, and puts the region focused on a relatively strong comprehensive killing effect concurrently.

Detailed description of the Invention
In order to achieve the goals of automating the process of pesticide application and providing good control over the amount of pesticide that is applied, the robotic pesticide sprayer combines a number of different types of components. Below is a short description of its main parts:

Arduino Uno Microcontroller: The RoboSpray Mechanic has a built-in Arduino Uno which acts as the main controller that interprets The and controls the spraying and movement of the robot. The structure is constructed in coordination with the other parts by integrating various sensors and actuators.

Bluetooth Module (HC-05): This module allows the Arduino board to receive commands from the android application. After connecting to a smartphone, farmers can send the robot to move, switch the sprayer on and off, and change the course of the robot.

Motor Drivers (L293D): The DC motors that furnish mobility are managed by the L293D motor drivers. Bidirectional control of the drivers enables all three axes of motion to be used: moving forward and backward, and turning.

DC Motors: The wheels of the robot move due to four brushless DC motors that enable it to move across different types of terrains. These motors are picked due to their capability to sustain considerable rough terrains and relatively their strength.

Servo Motors: The spray function of the robot incorporates a pair of servo motors which guide the spray nozzle to the desired orientation with accuracy. This prevents the over-application of pesticides since they are applied only in the required areas.
Relay Module and Buck Converter: The relay module is activated through an Arduino. It provides control over high-voltage circuits. The buck converter provides a safer level voltage to the pump by stepping down the output of a 12V battery.
Temperature and Humidity Sensors: These devices are equipped to monitor environmental conditions, and hence allow the robot to automatically alter its spraying activity according to weather. For example, in the event when the temperature or humidity level is quite high, the robot may decide to lower spraying activity in order to minimize loss to evaporation or excess spraying.
