FARMER WELFARE ROBOT

Project Description:

The Farmer Welfare Robot is an innovative solution designed to help farmers safely and efficiently spray pesticides in their fields. This autonomous robot aims to protect farmers from direct exposure to harmful chemicals, which can cause skin-related allergies and other health issues. The robot leverages the Arduino platform to navigate the fields and uniformly spray pesticides, ensuring both the health of the crops and the farmers.

Components Required:

• Arduino uno with cable x 1
• Motor Driver L298N x 1
• DC Motor x 3
• Jumper wires – Male to Female x 12
  Male to Male x 2
• 3.7v battery Li-ion 18650 x 3
• Lithium_ion Battery Holder x 1

Conclusion:

The Farmer Welfare Robot provides a practical and efficient solution for pesticide spraying, safeguarding farmers’ health and making field operations easy. This project uses basic electronic components and programming to deliver a valuable tool for modern agriculture. It also safeguards farmers from skin allergies that are caused by the pesticides.
