Time is a important issue when corresponding to people who come across a immediate fluctuation in the health. That may even occur sudden death of a person, if proper first aid is not provided until the provision of suitable medication through the doctor’s prescription. Therefore providing of immediate treatment i.e, first aid is must to the victim after collapsing. Day by day technology is growing in a drastic way, among which robotics is also one of such stream. Hence in this paper we are proposing an emergency aid for the victims, by providing required facilities to rescue from the sudden fluctuation in the health. Therefore with the help of an automated system an immediate rescue aid is provided.

Key words: Robot, Pulse sensor, Pulse sensor, Microcontroller, First aid kit.

Mechanical frameworks are one of the key answers for giving brilliant administrations. AMBUBOT is favored for a quick treatment utilizing Automated External Services to regulate the casualty inside a couple of minutes, by encouraging different methods of task from manual to self-sufficient working to spare somebody’s life in the required location. The model with biomedical sensors are utilized for checking the patient wellbeing. The area of the patient is being followed if there should arise an occurrence of crisis by means of GSM. The brilliant world is required to include sudden change detection, processing, and correspondence to accomplish complete interconnections of physical recognition, digital collaboration, social connection, and psychological reasoning. Expanding populace thickness in urban situations requests satisfactory arrangement of administrations and framework. This blast in city populace will show real difficulties including air contamination, activity clog, wellbeing concerns, vitality and waste administration. As a developing stage for that area, a portable robot can be utilized keeping in mind the end goal to encourage the medicinal services. Most rescuers happen not long after the occasion of a disaster happens. In that occasion, human rescuers will sort out the save wanting to get out to the territories, discover the casualties, and conversely, a portable robot would have the capacity to movement all through the earth and can put their position wherever its condition is required. Portable robot is a self-governing or semiautonomous machine that is proficient to move around in their condition and furthermore can perform different undertakings either with immediate or halfway control by human supervision or totally independent. With utilizing various sensors for route, this robot can explore from a point to a given goal without losing the right way.

1.HOOMAN SAMANI AND RONGBO ZHU proposed a model that assists in finding the persons sudden cardiac arrest using the using the smart health care kit.

2. Mr. M. Gajendiran, suggested a model that helps in taking care of a persons health through the simulation method using zigbee protocol with aurdino microcontroller connected with bp kit.

3.Hemavathi.R1, Karthigayini.V2, Kushma.N3, Megala.P4, Nithyapriya A.P5,, suggested a method that helps in maintaining the health of person using the sensors and Pic Controller, and also presented a literature review on Gps/Gsm, LCD.

Proposed methodology

Block diagram of the system
The proposed emergency vehicle robot for urban communities furnishes the administration of rescue vehicle with aid to help somebody having a health issue. A crisis message and current position of casualty will be created. Additionally, the message can be sent to the doctors for the medication help. It can be worked in auto or manual mode. This area of our task has the Micro-controller part appended with the Motor hand-off and with the wheels of the automated vehicle. The temperature and pulse sensors alongside the DC Battery is additionally seen in this segment.

Renesas microcontroller

The RL78 Family 16-bit microcontrollers are the joining of the high CPU execution and the magnificent on-chip elements of the R8C and the 78K, and offer a complete lineup of 10-128 stick and 1-512 KB items for the 8/16-bit showcase. Acknowledging industry-driving low power utilization at 46 ?A/MHz utilization amid typical task and 0.57 ?A/MHz amid clock activity, you can expect incredibly enhanced power proficiency utilizing RL78 microcontrollers. Worked in highlights, for example, a high-accuracy (±1%) rapid on-chip oscillator, foundation task information streak fit for 1 million modifies, temperature sensor, and interface ports for different power supplies help diminish framework expenses and size.


GSM/GPRS module is utilized to build up correspondence between a PC and a GSM-GPRS framework. Worldwide System for Mobile correspondence (GSM) is a design utilized for versatile correspondence in the vast majority of the nations. Worldwide Packet Radio Service (GPRS) is an augmentation of GSM that empowers higher information transmission rate. GSM/GPRS module comprises of a GSM/GPRS modem together with control supply circuit and correspondence interfaces (like RS-232, USB, and so on) for PC. The MODEM is the spirit of such modules. GSM/GPRS MODEM is a class of remote MODEM gadgets that are intended for correspondence of a PC with the GSM and GPRS arrange. It requires a SIM (Subscriber Identity Module) card simply like cell phones to actuate correspondence with the system. Additionally they have IMEI (International Mobile Equipment Identity) number like cell phones for their distinguishing proof.

Pulse sensor
Heartbeat Sensor is a very much outlined fitting and-play heart-rate sensor for Arduino. It can be utilized by understudies, specialists, competitors, creators, and diversion and portable designers who need to effectively fuse live heartrate information into their activities. The sensor cuts onto a fingertip or ear cartilage and fittings directly into Arduino. It moreover incorporates an open-source observing application that diagrams your heartbeat progressively. The front of the sensor is the entirely agree with the Heart logo. This is the side that reaches the skin. On the front you see a little round gap, which is the place the LED radiates through from the back, and there is additionally a little square simply under the LED. The square is a surrounding light sensor, precisely like the one utilized in cellphones, tablets, and PCs, to alter the screen brilliance in various light conditions. The LED sparkles light into the fingertip or ear cartilage, or other hairlike tissue, and sensor peruses the measure of light that ricochets back. The opposite side of the sensor is the place whatever remains of the parts are mounted. We put them there so they would not impede the of the sensor on the front. Indeed, even the LED we are utilizing is a turn around mount LED.

Temperature Sensor

Temp sensor model
The LM35 course of action are precision joined circuit temperature sensors, whose yield voltage is straightforwardly with respect to the Celsius (Centigrade) temperature. The LM35 thusly has ideal position over direct temperature sensors adjusted in Kelvin, as the customer isn’t required to subtract a significant predictable voltage from its respect secure accommodating Centigrade scaling. The LM35 does not require any outside arrangement or trimming to give regular correctnesses of ±1?4?C at room temperature and ±3?4?C over a full ?55 to +150?C temperature go. Negligible exertion is ensured by trimming and modification at the wafer level. The LM35’s low yield impedance, coordinate yield, and correct inherent modification make interfacing to readout or control equipment especially straightforward. It can be used with single power supplies.

20*4 lcd display
It is a alpha-numeric liquid crystal display, through which the messages will be displayed and also the statements required to give during the time of first aid is displayed. We have used 20*4 lcd display. Also the power supply is given through battery.

Experimental Results

Temp and heartrate is being dlayed on lcd

First aid procedure is displayed on lcd
The entire system is shown in the above picture, which is mounted with the microcontroller in the centre corresponding with gsm, pulse sensor and temperature sensor with the dc motor and also it consists of medical kit. Hence android application is devised and operated through gsm. Through the application the patients pulse rate and the temperature will be sent to the doctor.

In today’s world time is a crucial issue in all the ways but when dealing with the health issues time plays a vigorous role in every persons life. The individual who gets sudden breakdown in the health needs to be cared immediately. Therefore for this reason an efficient means has to be taken in consideration. So, in this paper we have analysed and developed a machine robot that carries a first aid kit upon it to the place where the medical emergency is required to save the lives when in need.
