Abstract: The project "Car Parachute Ejection System" focuses on enhancing vehicle safety by designing an automated emergency braking mechanism using a parachute deployment system, integrated with real-time obstacle detection and emergency alert capabilities. The system is built around an Arduino microcontroller, which controls a small car model equipped with four BO motors (100 RPM) driven by an L293N motor driver, enabling precise movement and speed control. The car is wirelessly operated via a Bluetooth connection using the HC-05 module, allowing users to control it through a Serial Bluetooth Terminal app. An ultrasonic sensor mounted at the front continuously monitors the surroundings for obstacles; upon detecting an imminent collision while the car is moving at high speed, the system triggers the release of a parachute from the rear, significantly reducing the vehicle's momentum to prevent accidents. Additionally, the system incorporates a GSM SIM800L module to send emergency SMS alerts, paired with a NEO-6M GPS module to transmit the vehicle's real-time coordinates to predefined contacts, ensuring prompt emergency response. This project combines mechanical, electronic, and communication technologies to create a robust safety mechanism, demonstrating the potential for scalable applications in full-sized vehicles. The integration of obstacle detection, rapid deceleration via parachute deployment, and automated emergency messaging highlights the system's innovation in addressing critical safety challenges. By leveraging affordable and widely available components, the project offers a cost-effective solution for enhancing vehicular safety, particularly in scenarios where traditional braking systems may be insufficient. The successful implementation of this prototype lays the groundwork for further advancements in autonomous safety systems, with potential adaptations for drones, high-speed robotics, and even aerospace applications. The project not only showcases the practical application of Arduino-based control systems but also emphasizes the importance of real-time data transmission and emergency responsiveness in modern safety solutions. Future enhancements could include multi-sensor fusion for improved obstacle detection, machine learning algorithms for predictive collision avoidance, and integration with IoT platforms for centralized monitoring. Overall, this project serves as a proof of concept for an innovative safety mechanism that could revolutionize emergency response in automated and remote-controlled vehicles.
