Our mission is to create autonomous aerial solutions that can assist in:
🌪️ Post-disaster surveillance (floods, earthquakes, landslides, fire zones)
📡 Search & rescue missions with onboard sensors & custom antenna systems
🚑 Medical & supply delivery in inaccessible zones
🛰️ Real-time data collection & transmission, even in disrupted networks
🛡️ Self-protection & defense mechanisms to ensure mission reliability in harsh conditions
This repository hosts everything from CAD designs to ROS2 simulation environments, enabling both hardware prototyping and virtual validation.

🚀 Features
🔍 Autonomous Navigation
Complete open-source flight control algorithm (Python) with integrated PID tuning for stable and precise UAV maneuvers.
🧠 Onboard AI ( ML Object Detection)
Jetson/Raspberry Pi powered real-time object detection for victim recognition, hazard detection, and intelligent mission planning.
🚑 Survival Kit Delivery
Payload delivery mechanism for first-aid kits, communication devices, and essential supplies in inaccessible disaster zones.
🎥 Long-Range Video & Data Transmission
Uses GStreamer + MQTT for low-latency HD video and sensor telemetry streaming over long distances.
📡 Custom Triple-Band Patch Antenna
Supports 5.8 GHz, 2.4 GHz, and 900 MHz for redundancy and range, ensuring communication even in disrupted networks.
⚙️ PID Tuning & IMU Data Integrity
Fine-tuned PID controllers with sensor fusion (IMU + GPS), combined with data integrity checks and encryption.
🛡️ Anti-Jamming & FHSS (Frequency Hopping Spread Spectrum)
Defensive communication strategy to counter signal interference, with compliance-based declination of offensive jamming use.
