🚀 Introducing Project KAVACH — Kinetic Animal Vigilance & Automated Crop-Guard Harness 🌱🛡️
We’re excited to share what Team Bhumi built at Tetrathon 2026!
🏆 Top 40 out of 400+ teams!
Although we couldn’t make it into the Top 10, reaching the Top 40 gave us an incredible opportunity to turn our idea into a working AI + hardware solution and present it at the event.
🌾 What is KAVACH?
KAVACH is an AI-powered automated crop protection system designed to detect unwanted entities around agricultural fields and respond intelligently based on the situation.
At its core is the Rakshak Tower — a modular agricultural protection tower designed by our team with Basic, Standard, and Premium configurations, allowing customization for different farm requirements and budgets.
⚙️ How it works
PIR Sensor → Camera → YOLOv8 → Decision System → Raspberry Pi → Action
🔹 PIR sensors provide the first level of detection.
🔹 Cameras activate when activity is detected.
🔹 YOLOv8 with COCO-pretrained weights identifies animals, birds, and humans.
🔹 The decision system determines the appropriate response.
🔹 Animals/birds can trigger suitable deterrent mechanisms.
🔹 When a human is detected, no deterrent action is triggered, preventing unnecessary activation around people.
⚡ Power-Efficient Design
Using PIR as the initial trigger helps reduce unnecessary camera and system operation. Combined with the solar-powered Rakshak Tower, this improves the overall energy efficiency of the concept.
