🤖 Autonomous Weed Removal Robot: Precision Weed Control for Farms and Gardens

🤖 Autonomous Weed Removal Robot: Precision Weed Control for Farms and Gardens

By Ronen Kolton Yehuda (Messiah King RKY)

🌿 Introduction

As agriculture moves toward automation and sustainability, one of the most persistent challenges remains weed management. Traditional weed control methods—manual weeding, herbicide application, or plastic mulching—are labor-intensive, environmentally harmful, or inefficient. Enter the Autonomous Weed Removal Robot: an AI-powered machine that identifies, extracts, and collects weeds with precision.

This robotic system is designed for use in both large-scale farms and residential or urban gardens, offering a clean, chemical-free approach to weed control.

🎯 Core Functions

The robot performs three primary actions:

1. Weed Detection
   Using computer vision and AI models trained on plant databases, the robot can differentiate weeds from crops based on leaf shape, color, position, and growth pattern.

2. Mechanical Removal
   The robot features a robotic arm or claw that grabs the weed by the base, pulls it from the soil (including roots), and ensures complete extraction.

3. Waste Collection & Transport
   Extracted weeds are stored in an onboard collection bin, which is periodically emptied into a designated composting or waste area—or transferred to a centralized green waste pile.
