An automatic fire extinguisher robot is a hardware Autonomous Things are expected to proliferate in the based model used for extinguishing the fire coming decade, with home robotics and the automatically during fire accidents. This robot will autonomous car as some of the main drivers.

The robot The branch of technology that deals with the design, shield is coated with some special material that is construction, operation, and application of robots, as capable of withstanding very high temperature. It takes long time for human to can take the place of humans in dangerous take action on extinguishing the fire. Even if we put environments or manufacturing processes, or fire alarms, it takes long time for the fire brigade to resemble humans in appearance, behavior, or reach the location.

By that time it can cause huge loss cognition. Many of today's robots are inspired by of properties. This robot does not require any human nature contributing to the field of bio-inspired presence. These robots have also created a newer branch of robotics: soft robotics. It can start extinguishing the fire immediately so that the fire does not spread a lot and can be controlled Robots have replaced humans in performing repetitive easily.

As soon as the fire starts, human fire brigade is and dangerous tasks which humans prefer not to do, also informed to be on the safe side. The robot finds or are unable to do because of size limitations, or its applications in rescue operations during the fire which take place in extreme environments such as accidents where possibilities for service men to enter outer space or the bottom of the sea.

Thus the fire can be extinguished. They work because raising the temperature of a semiconductor increases the number of active charge carries — it promotes them into the conduction band.

The more charge carries that are available, the more current a material can conduct. In certain materials like ferric oxide with titanium doping a n-type type semiconductor is formed and the charge carriers are re electrons.

Know about the Working of Fire Fighting Robot Project

Embeds 0 No embeds. No notes for slide. Building a robot requires expertise and complex programming. A fire fighter robot is one that has a small fire extinguisher added to it. By attaching a small fire extinguisher to the robot, the automation put out the fire by human controlling.

This paper covers the design and construction of a robot that is able to sense and extinguish fire. This robot implements the following concepts: This robot processes information from its various sensors and key hardware elements via microcontroller. It uses thermistors or ultraviolet or visible sensors to detect the fire accident. A robot capable of extinguishing a simulated tunnel fire, industry fire and military applications are designed and built. Once the flame is detected, the robot sounds the alarm with the help of buzzer provided to it, the robot actuates an electronic valve releasing sprinkles of water on the flame.

The project helps to generate interests as well as innovations in the fields of robotics while working towards a practical and obtainable solution to save lives and mitigate the risk of property damage. Fire fighters face risky situations when extinguishing fires and rescuing victims, it is an inevitable part of being a fire fighter.

In contrast, a robot can function by itself or be controlled from a distance, which means that fire fighting and rescue activities could be executed without putting fire fighters at risk by using robot technology instead.

In other words, robots decrease the need for fire fighters to get into dangerous situations. This robot provides fire protection when there is a fire in a tunnel or in an industry by using automatic control of robot by the use of microcontroller in order to reduced loss of life and property damage.

This robot uses dc motors, castor wheel, microcontroller, sensors, pump and sprinkler. Microcontroller is the heart of the project. Microcontroller controls all the parts of the robot by the use of programming.

In this robot as the fire sensor senses the fire, it sends the signal to microcontroller; since the signal of the sensor is very weak the amplifier is used 2. As soon as microcontroller receives the signal a buzzer sounds, the buzzer sound is to intimate the occurrence of fire accident. After the sounding of the buzzer microcontroller actuates the driver circuit and it drives the robot towards fire place, as the robot reaches near the fire microcontroller actuates the relay and pump switch is made ON and water is sprinkled on the fire through the sprinkler.

Robotics is a branch of applied science, the popular conception of which came not from science, but from drama, fiction and cinema.


This budding of the new science in the cradles of arts had two-fold results. On the other hand, a myth was created in the minds of lay- men regarding human-like machines called robots, the sophistication of which is quite phenomenal. An actual industrial robot can, of course, look similar to a human arm, in basic mechanical architecture. For example, the motion capabilities of a six degrees of freedom PUMA robot can be explained in analogy with movements at shoulder, elbow and wrist of a human arm.

The four principal components of a robot, namely the manipulator, the controller, the sensors and the actuators roughly resemble in function though not in appearance the human arm, brain, sense organs and muscles.

A Fire-Fighting Robot Using Arduino

In that perspective, hard automation systems and numerically con- trolled NC machines do not fall within the scope of robotics. Teleoperators or telerobots also fall near the border line.

Though pro- grammable machines existed even in the 19th century, the science of robotics came into being in the last 50 years through the epoch-making developments of first telerobot to handle radioactive material world war II , first servoed electric-powered teleoperators —48 , NC machines , first reprogrammable robot and the installation of the first robot Nowadays, robots are used for material handling, welding, spray-painting, teleoperations in inaccessible and or hazardous places , assembly, machining etc.

With this introduction to the field of robotics, let us have a look at the recent trends in robotic research and application, which can be described under the following broad headings. But, with a given architecture of a robot arm and a given working environment, restrictions of workspace, dexterity and obstacles call for additional degree s of free- dom.

In such cases, as a human being uses additional freedoms of the body to supplement the capabilities of the arm for enhancing the reach, manipulate objects comfortably and reach below the table or around the corner objects, additional degrees of freedom can be provided in the robot arm with extra joints and links.

Such robots are called redundant robots because they use more inputs than necessary and are used for the purposes of workspace enhancement and avoidance of singularities and obstacles. With a redundant robot, a particular point can be reached in infinite number of ways — to choose one of those infinite ways is the problem of redundancy resolution, which is solved by optimizing the performance.

Conventional modelling of robot manipulators needs to consider the links of a robot as rigid, for which the deflections have to be negligible from the viewpoint of positional accuracy.

Consequently, the links are to be designed stronger than necessary and heavy. But, from a physical point of view, it is not necessary and we should not mind the links being flexible as long as they are within elastic limits and we know their behaviour. So, the recent interest has been to work with flexible robots and to take advantage of their light weight by incorporating their flexibility into the mathematical model which, of course, complicates the dynamics of the system a price to be paid for the advantage gained.

Actuations off the base aggravate this problem and make the robot bulky. Consequently, the serial robots tend to bend at high load and vibrate at high speed. Though they possess a large workspace, the positioning capability is rather poor.

So, where high load carrying capacity and precise positioning is of prime concern, an alternative is provided by parallel-actuated and closed-loop robots which have attracted tremendous research interest in the last 15 years. As a human being uses both arms to handle a heavy load, three fingers in parallel for doing a precise work like writing and as animal body is supported on four legs with provision of in-parallel actuation at the leg joints, robot manipulators also can be designed with the end effector hand connected to the frame by parallel chains of joints and links having the actuations distributed among the various chains or legs.

Parallel robots, in general, provide high structural rigidity and load carrying capacity, good positioning capabilities and have less vibration. But, they generally have 5. OFECEPage5 restricted workspaces and their kinematics and dynamics is quite complicated to study and analyse.

Typical applications of parallel robots include applications where high load capacity and precise positioning are required, use as an assembly workstation, dexterous wrist and micromanipulators. The application of the concept of parallel actuation has uses in cooperating robots and in multi-fingered gripping and manipulation. In ordinary life, we use trains, automobiles and animals for conveyance.

Similarly, in robotics, we have tracked, wheeled and legged vehicles. Though all of these have their own applications, walking machines have enjoyed the maximum research interest due to their versatility over terrain irregularities and greater mobility, and work is mostly focused on machines walking on two to six legs.

Till now, most of these walking machines have succeeded mostly in laboratory conditions and have achieved little breakthrough on completely unstructured ground, but the attempts in this direction promise a high potential.

Recently BARC has developed a walking machine with six legs presented in National Convention on Industrial Problems in Machines and Mechanisms which moves forward and can take turns also, but the walking speed is quite low.

A challenging field of research is biped locomotion which gives rise to a problem of stability, which is evident as equilibrium of a body with less than three supports is precarious.

The ease of biped locomotion in human beings can be attributed to their erect body structure, the extent and nature of the surface of the foot and an extremely smart nervous system — conditions simulating which in machines is a really challenging task.

The current trend is towards model-based control, where the dynamic forces are incorporated in the control strategy as feed forward gains and feed- back compensations along with the servo-controller which is required only to take care of external noise and other factors not included in the dynamic model of the robot. As is expected, the model-based control scheme exhibits better performance, but demands higher computational load in real time.

A particular 6. OFECEPage6 area of model-based control is adaptive control, which is useful when the dynamic parameters of the robot are not well-known a priori. The controller adapts itself during execution of tasks and improves the values of the dynamic parameters. But certain tasks e. Cur- rent trend is to control the force in such directions in such applications and position in other directions.

The use of compliance flexibility also is getting popular in control. In applications like insertion of a peg into a hole, if the positional accuracy is poor, the forces stemming from such errors tend to correct the position, if some compliance is provided at the wrist.

Again, knowledge is much more than a collection of pieces of information. Still, the intelligent robots, as they are called, constitute an extremely popular topic in robotics, because they can perform various tasks in an apparently intelligent manner. For example, machine intelligence can be applied for path planning and obstacle avoidance by maintaining and updating a complete CAD model of the working environment such that the robot navigates through obstacles without collision.

As sight, sound and touch assist human intelligence so far as the knowledge of the external world is concerned, robots also are equipped with sensors optical, ultrasonic, tactile for feedback.

In the whole processing of an image, the interpretation of a scene is the most difficult task and requires highest level of intelligence. OFECEPage7 The maturity of this technique is expected to provide tremendous decision-making capabilities to the robots.

The dream of perfection for the science of robotics is a system equipped with high- performance sensors and stereo vision, such that it can work in unstructured environment where changes in scenario may be rapid and unexpected. In addition, certain degree of fault- tolerance is desirable with decision-making capabilities such that it can perform tasks assigned to it as long as they are physically possible.

In Norbert Wiener formulated the principles of cybernetics, the basis of practical robotics. Fully autonomous robots only appeared in the second half of the 20th century. The first digitally operated and programmable robot, the Unimate, was installed in to lift hot pieces of metal from a die casting machine and stack them.

Commercial and industrial robots are widespread today and used to perform jobs more cheaply, or more accurately and reliably, than humans. They are also employed in jobs which are too dirty, dangerous, or dull to be suitable for humans. Robots are widely used in manufacturing, assembly, packing and packaging, transport, earth and space exploration, surgery, weaponry, laboratory research, safety, and the mass production of consumer and industrial goods.

Robotics is based on two enabling technologies: Telemanipulators and the ability of numerical control of machines. Telemanipulators are remotely controlled machines which usually consist of an arm and a gripper. The movements of arm and gripper follow the instructions the human gives through his control device. First telemanipulators have been used to deal with radio-active material. Automatic Programmed Tools. The combination of both of these techniques leads to the first programmable telemanipulator.

The first industrial robot using these principles was installed in These are the robots one knows from industrial facilities like car construction plants.

The development of mobile robots was driven by the desire to automate transportation in production processes and autonomous transport systems. New forms of mobile robots have been constructed lately like insectoid robots with many legs modelled after examples nature gave us or autonomous robots for underwater usage.

Humanoid robots are being developed since when Wabot-I was presented in Japan. The current Wabot-III already has some minor cognitive capabilities. Although it is remote controlled by humans it can walk autonomously on the floor and stairs.

Robots are physical agents that perform tasks by manipulating the physical world. They are equipped with sensors to perceive their environment and effectors to assert physical forces on it covered in more detail in next section. As mentioned before Robots can be put into three main categories: The base object is the agent who is the "actor".

It is realized in software. Robots are manufactured as hardware. The connection between those two is that the control of the robot is a software agent that reads data from the sensors decides what to do next and then directs the effectors to act in the physical world. For example, a mercury-in-glass 9. OFECEPage9 thermometer converts the measured temperature into expansion and contraction of a liquid which can be read on a calibrated glass tube.

A thermocouple converts temperature to an output voltage which can be read by a voltmeter. For accuracy, most sensors are calibrated against known standards. The exact nature of this device depends on the application of the robot. In the strict definition, which originates from serial robotic manipulators, the end effectors means the last link or end of the robot.

At this endpoint the tools are attached. In a wider sense, end effectors can be seen as the part of a robot that interacts with the work environment. This does not refer to the wheels of a mobile robot or the feet of a humanoid robot which are also not end effectors—they are part of the robot's mobility. It would do this in ways that are not unsimilar to the way that you sense your surroundings. Giving your robot sensors: Whether rolling on wheels, walking on legs or propelling by thrusters a robot needs to be able to move.

To count as a robot either the whole robot moves, like the Sojourner or just parts of the robot moves, like the Canada Arm.

The main components are: IR Photo Diodes are used as sensors. These sensors are connected to ADC pins of the microcontroller. IR Photo diodes are connected in reverse bias to be operated as photo diodes otherwise they will be operated as normal diodes. The voltage variations of the sensors is given as inputs to the Micro controller and accordingly the robot is operated.

The direction of the robot is controlled using joysticks. The terminals of joysticks is connected to ADC pins of micro controller. Joysticks are usually the potentiometer, the potential variations is given as an input to micro controller and robot is operated accordingly.

Motor drivers are used to describe the direction of movement of the robot. It is used to give high voltage and high current as an output to run the motors which are used in the project for the movement of the robot. In this project we use simple DC motor for the rotation of the wheel which are responsible for the movement of the robot. Usually DC motors convert electrical energy into mechanical energy.In this robot has a switch which is used to switch between manual and autonomous mode.
