Designing of the basic structure of the vehicle is to be done primarily. The design process will be performed in Solid- works CAD software. Finite elemental force analysis will be performed using suitable simulation software and obtained results will used for analysis and optimization of the design. Materials required for the development of the vehicle are to be determined on basis of structural and fire-resistant properties. The processes and procedures for fabrication are determined on the basis of requirements and availability of resources. Design of the tank tread mechanism is to be done. Drive for the vehicle is to be obtained from a dc motor. Since it’s been planned to obtain directional control by alternative operation of tank tread on both sides, so two motors are needed. The selection of motor based on the torque and speed requirements is to be done. The dc power source for operating the motor are obtained from the batteries mounted on the vehicle itself. Fire resistivity can be enhanced by giving a coating of fire retardant materials. Water or the other fire extinguishing fluid is pumped from an external source through a pipe to the vehicle. A direction controllable nozzle is embedded through which any required angular position can be setup, thereby facilitating us to target any specific area of fire. Realization of the direction of movement, identification of obstacles, location of fire etc. is obtained through a live camera feed. Assembly of the above- mentioned components in their respective slots will ensure effective and reliable working of the vehicle as a complete system.
A robot is an automatic mechanical device often resembling a human or animal. Modern robots are usually an electro-mechanical machine guided by a computer program or electronic circuitry. Military robots are autonomous robots or remote-controlled devices designed for military applications. MIDARS, a four-wheeled robot outfitted with several cameras, radar, and possibly a firearm, that automatically performs random or pre-programmed patrols around a military base or other government installation. It alerts a human overseer when it detects movement in unauthorized areas, or other programmed conditions. The operator can then instruct the robot to ignore the event, or take over remote control to deal with an intruder, or to get better camera views of an emergency. The robot would also regularly scan radio frequency identification tags placed on stored inventory as it passed and report any missing items. The applications involved in the robot surveillance, fire, shooting, and Bluetooth app and stop the firing. Surveillance robot is to recognize and detect motion automatically around a robot's environment. The robot design has been partitioned into control, and planning subsystems. Robotic surveillance appliance is built on a moving platform designed for surveillance and security tasks. This robot can be operated in “remote eyes” or “automatic trip” modes. Fire produced with spray and by energizing the graphite lead with battery supply which leads to produce spark on lead. Then the spray is been activated by the motor and it is sprayed on to the lead which produces a bunch of flames till the gas inside the spray bottle last’s. Shooting is been produced by the pressurized gas stored in the tank. With the help of solenoid ball wall which is been opened and closed with the help of a motor & when it is been opened the pressure runs out for escape and it is directed to flow through the PVC pipe and that pressure from the pipe shoots the object inside the pipe. The control of the complete process is done with the help of micro- controller (AT mega 328p) which is known as Arduino and it is been controlled wirelessly through Bluetooth
Firefighters are rescuers to put out hazardous fires that threaten civilian populations and property, to rescue people from collapsed and burning buildings, car accidents, and other such situation. Collapsing buildings, explosions and poisonous fumes all pose a serious threat to the lives and limbs of fire crews. Currently, there are many technologies that assist firefighters to fight against fire such as firefightingvehicle, fire extinguisher, mobile water supply, and firefighting machine.
technology for drastically reducing the environmental burden of road transport. More than a decade ago and also more recently, they were advocated by various actors as an important element in reducing CO2 emissions of particularly passenger cars and light commercial vehicles as well as emissions of pollutants and noise. By green vehicle we can reduce also the foreign currency and maximize the country economic development because the usage of fuel is reduced and the vehicle uses alternative energy such as electrical, solar energy and other sources. This will happen by reducing the weight of chassis.
Equipment and technology readiness status is the base of combat readiness, is the comprehensive embodiment of equipment reliability, repairability, and security, is an important guarantee for the Fighting Strength Forming. The implementation of technical condition detection and performance assessment of armored equipment is conducive not only to accurately grasping the basic situation of equipment, providing the basis for the deployment of combat readiness, but also conducive to the daily management work, and which is also the base of making the equipment plan of campaign, training plan and the maintenance plan ,the basic work of equipment management work, as well as the major means of keeping war equipment working well.
The use of ventilation systems to control smoke movement is common in most road tunnel designs. The operation of the tunnel ventilation system is critical as its purpose during a fire emergency is to control the movement of smoke and heated gas away from the fire to provide a tenable environment along the egress path allowing for safe evacuation of motorists. The secondary purpose is to facilitate fire fighters access to the incident by providing a clear path to the fire site (Bendelius 2003). The risk of having a fire in a tunnel and designing an effective tunnel ventilation system through the provision of sufficient airflow to achieve tenable conditions in the egress path is dependent on multiple parameters including heat release rate (HRR), tunnel geometry, tunnel gradient, operation (whether bi-directional traffic is required) (Bendelius 2003) and legislation (whether vehicles carrying dangerous goods are allowed to access the tunnel, e.g. petrol tankers). Among these parameters, the heat release rate is the primary parameter for tunnel ventilation design and it is the most difficult to identify as this value is dependent on the types of vehicles and any associated loads carried by the vehicles. In current practice, the heat release rate for various types of fires proposed by the PIARC 1999 technical committee reports (PIARC 1999), NFPA 502 (NFPA 2004), BD78/99 (BD 1999) have generally been used for the design of tunnel ventilation systems. The heat release rates for the various types of vehiclefire range from 2.5 MW to 5 MW for passenger cars to 20 MW to 30 MW for heavy goods vehicles (HGV). However, recent fire experiments conducted in the Runehamar Tunnel showed that vehicles with burning goods may result in higher HRR (approx 66.4 to 201.9 MW peak) outputs (Ingason and Lonnermark 2005). These experiments seriously hinted that previous data regarding heavy goods vehicles might have been underestimated.
We design a low cost based security robot system to detect abnormal and dangerous situation and notify us. The traject interface may be Internet or GSM(Global System for Mobile). The structure of the security robot contains six parts. There are security system, avoid obstacle and driver system, software development system, auto recharging system, far supervise system and others. First, we structure a mobile robot using aluminum flame. Then, we develop a multisensor– based sensor system for the safety of robot, and we also present the remote mobile Security system(RMS)for the security robot system. Finally, we make some experimental scenario to supervise the security robot through the personal computer, and we can get bestl results for the low cost security robot.
In the research, the development of technology on firefighting is in progress around the world. Most of the tools and equipments are manually operated by the fireman. In the new era of technology, the advances technology of firefighting machines is most conquered by the Western Country.

This project discusses the development of a machine, capable of finding it’s way through a maze of rooms, searching for a fire and extinguishing it. Though the scale of the machine is comparatively small and its ability to put out a fire. It may not be suitable in some environments but the basic idea, structure and navigation skills can be employed in real situations. There are certain situations that may be suitable and also not suitable for the machine to operate.
Environmental as well as economical issues provide a compelling impetus to develop clean, efficient, and sustainable vehicles for urban transportation. Environmental technology or green technology is the application of the environmental science to conserve the natural environment and resources, and to curb the negative impacts of human involvement. One of focus area in green technology is energy and that includes the development of the alternative fuel or recycles energy. When people continue to exploit the earth for natural resources, they are increasingly aware of the damage caused by their actions. In the last century, people increasingly realize how serious environmental damage due to their actions and this makes them increasingly trying to rectify this situation. Since 70% of the sources of air pollution caused by fossil fuel use, it is logical for people to limit consumption of fossil fuels, particularly oil.
________________________________________________________________________________________________________ Abstract - This paper provides in-detail description of the design and structural analysis of chassis and suspension system of a standard All-Terrain Vehicle. The design and development comprises of material selection, chassis and frame design, cross section determination, and determining strength requirements of roll cage, stress analysis, design of the entire double wishbone suspension system and simulations ton test the ATV against failure. The static and dynamic structural analysis is also done on the chassis for validating the design. Initially, a prototype design of the chassis was made as a 3-D CAD model using Solidworks CAD software. The designed ATV is an off-road vehicle powered by 305 cc, four strokes, 10 BHP engine Brigg Stratton engine and driven by manual transmission. Material selection was based on the basis of factors like weight, cost, availability and performance during the entire design process, consumer interest through innovative, inexpensive, and effective methods was always the primary goal. The manufacturing objective is to design a vehicle which is safety ergonomic, aerodynamic, highly engineered and customer satisfaction which can make it highly efficient. The proposed design of ATV can navigate all most all terrain which is the primary objective behind the design and fabrication of any all-terrain vehicles.
chassis is the under part of a motor vehicle, consisting of the frame (on which the body is mounted). If the running gear such as wheels and transmission, and sometimes even the driver's seat, are included, then the assembly is described as a rolling chassis. In the case of vehicles, the term rolling chassis means the frame plus the "running gear" like engine, transmission, drive shaft, differential, and suspension. A body (sometimes referred to as "coachwork"), which is usually not necessary for integrity of the structure, is built on the chassis to complete the vehicle. For commercial vehicles, a rolling chassis consists of an assembly of all the essential parts of a truck (without the body) to be ready for operation on the road. The design of a pleasure car chassis will be different than one for commercial vehicles because of the heavier loads and constant work use. This describes the lower hull, although common usage might include the upper hull to mean the AFV without the turret. The hull serves as a basis for platforms on tanks, armored personnel carriers, combat engineering vehicles, etc. Traditionally, the most common material for manufacturing vehiclechassis has been steel, in various forms. Over time, other materials have come into use, the majority of which have been covered here.
kind. This firefighting machine is still in researh and development phase as to overtake all the problems that occur. This firefighting machine was built to do a firefighter job, thus the body of the machine must be able to sustained high temperature. It also must be able to expand and point the water spray at certain high and at certain distance. The high and the length of the machine is controlled by hydraulic systems. The ‘boom’ hydraulic system controls the water spray while the other two cylinders control the angle and height of the ‘boom’.

In this project is to build a Firefighting robot device that can response or detect and extinguish a fire on its own is long past due. Many house fires originate when someone is either sleeping or not home. With the invention of such a device, people and property can be saved at a much higher rate with relatively minimal damage caused by the fire. The motivation behind of firefighting robot is the desire to save human lives. Currently, we rely on human beings to enter burning buildings and extinguish fires. Using a robot to put out fires will eliminate the risk of injury or death to the fire fighter.
