Anti-Down Vehicle

Published on Feb 12, 2017


Drowning itself is quick and silent, although it may be preceded by distress which is more visible. A person drowning is unable to shout or call for help, or seek attention, as they cannot obtain enough air. The instinctive drowning response is the final set of autonomic reactions in the 20 – 60 seconds before sinking underwater, and to the untrained eye can look similar to calm safe behavior.

In this project we are introducing an anti drown vehicle which helps to escape from vehicle accidents. The vehicle gets accident and it will be sinking in water, at that time the sensors inside the vehicle will active and the circuit will have shorted with the presence of water. At that time the balloon fitted with the vehicle will fill with the gas and it will extract at that time we can escape from sinking.


The main aim of this project is to avoid the accidents. The accidents during when the vehicles fall into water the safety balloon fitted with the vehicle will protect the vehicle from sinking water. The main working parts of this system are a microcontroller unit and the balloon in the vehicle. The balloon made with hard plastic and which will help to avoid the accident.

A microcontroller (sometimes abbreviated µC, uC or MCU) is a small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals. Program memory in the form of (NOR flash or OTP ROM) is also often included on chip, as well as a typically small amount of RAM. Microcontrollers are designed for embedded applications. Microcontrollers are used in automatically controlled products and devices, such as automobile engine control systems, implantable medical devices, remote controls, office machines, appliances, power tools, toys and other embedded systems.

By reducing the size and cost compared to a design that uses a separate microprocessor, memory, and input/output devices, microcontrollers make it economical to digitally control even more devices and processes. Mixed signal microcontrollers are common, integrating analog components needed to control non-digital electronic systems


There are batteries, dc motor, liquid propellant, and a connecting circuit is there, they are the main components of this vehicle which will do an important role in this project. The vehicle will run with the working of motor and if the vehicle gets accident the sensor inside the vehicle will active when contact with the water. The sensor will be connected with the liquid propellant in the system, the gas will fill the balloon and the vehicle can stand steadily in the surface of water.

In this project we are using balloon as an important part, the balloon gives the vehicle more safety. The balloon will fit with the vehicle and it will be use in the situation of accident. If the vehicle gets accident and fall into water, at that situation the sensors inside the vehicle will be alert and the circuit will be short with the presence of water, due to this the gas inside the vehicle will fill the balloon and the vehicle can be easily floated in the water.
