Documentation for Raptor
Introduction
Raptor is an AI-powered smart helmet designed to enhance rider safety through real-time accident
detection and emergency alert systems. The helmet integrates IoT sensors, AI-based crash detection, and
automated emergency response mechanisms to ensure immediate assistance in case of an accident.
With the rising number of road accidents involving two-wheelers, many riders fail to receive timely
medical attention, leading to severe consequences. Raptor aims to solve this by automatically detecting
crashes and alerting emergency contacts with real-time location details.
Project Motivation
Road safety is a critical issue worldwide, especially for motorcyclists. While conventional helmets
provide physical protection, they lack smart features to assist riders in emergencies. Raptor goes
beyond traditional helmet designs by integrating AI-driven crash detection and real-time communication
to save lives.
Key Features & Implementation
1. AI-Based Crash Detection System
Accelerometer & Gyroscope Sensors detect sudden impact, abrupt
motion changes, and helmet tilt
angles,
determining if a crash has occurred.
→ AI algorithms analyze sensor data to distinguish between a normal fall and a severe accident.
→ The system prevents false alarms by using Impact Threshold models trained on real-world riding data.
2. Emergency Alert & Live Location Sharing
Upon detecting an accident, Raptor automatically sends an SOS alert to emergency contacts.
→ The alert includes the rider’s live GPS location, allowing responders to reach the accident site
quickly.
→ Uses ESP-32 module for real-time location tracking, even in low-connectivity areas.
3. Fall & Unconsciousness Detection
If a rider falls but doesn’t move for a certain period, the system assumes unconsciousness and triggers
emergency alerts.
→ Integrated pulse sensor & body temperature monitor can detect abnormal rider conditions.
4. Smart Helmet Lock System (Prevention Feature)
The helmet has an ignition-locking mechanism, ensuring the bike won’t start unless the helmet is worn.
→ Uses RFID/NFC authentication for secure user verification before ignition.
5. Mobile App Integration for Alerts & Tracking
The helmet connects to a mobile app via Bluetooth, allowing riders to:
→ View ride analytics & helmet status.
→ Receive battery & sensor health alerts.
→ Customize emergency contact details.
→ The app is designed with a clean, user-friendly UI, ensuring easy navigation and real-time monitoring.
6. Voice Assistance & Hands-Free Communication
Built-in Bluetooth speakers & microphone allow for hands-free calls and navigation assistance.
→ AI voice commands enable riders to control features without distraction.
