Accident Identification and alerting project

When an individual riding his/her bike, meets with an accident, there is a chance that the individual may suffer from a serious injury or expire instantaneously and there is no one around to help him. Well this system is a solution to the problem. The system acts as an accident identification system that gathers and sends this vehicle information that met with an accident, and conveys it to the nearest control room.
For this the user vehicle is fixed with an RF transmitter circuit that has a vibration sensor along with microcontroller, RF encoder and also fitted with an RF transmitter. Each and every control room must have an RF receiver fitted to receive the transmission. Whenever a user vehicle meets with any accident, the vibration sensor detects and gives its output. This output is then detected by the microcontroller. Now the microcontroller sends this change detection signal to an RF transmitter. The RF transmitter now intern begins transmitting this accident data. The nearest RF transmitter reads the signal and then shows it on an LCD screen. The person monitoring the LCD screen may react to it, reach the accident location and help the needful.

Soldier Health & Position Tracking System The soldier Health and Position Tracking System allows military to track the current GPS position of soldier and also checks the health status including body temperature and heartbeats of soldier. The System also consists extra feature with the help of that soldier can ask for help manually or send a distress signal to military if he is in need. The GPS modem sends the latitude and longitude position with link pattern with the help of that military can track the current position of the soldier. The system is very helpful for getting health status information of soldier and providing them instant help. The nation’s security is monitored and kept by army, navy and air-force. The important and vital role is of soldiers who sacrifice their life for their country. There are many concerns regarding the safety of the soldier. Soldiers entering the enemy lines often lose their lives due to lack of connectivity, it is very vital fo

Introduction to robotics .............. Part-3 (Automation)

Automated Portable Hammering Machine Hammering is the most widely used industrial as well as construction activity. Hammering or screws, metal sheets, parts etc requires a lot of time and effort. So here we propose an automated hammering system that allows for fully automatic hammering process. This allows for accurate, fast and automated hammering wherever and whenever needed using a 12V battery. The person just needs to insert workpeice and start the hammering machine. This machine can be used for automatic hammering work as and when needed. We here use a dc motor in order to move the hammer. The DC motor consists of a pulley attached to it which is connected to a larger pulley for efficient power transfer and to increase torque. This large pulley is connected to a shaft that has a connecting rod attached to it. This rod is used to achieve lateral motion from the spinning shaft. We now connect the other end of hammer to this connecting rod through a mid swinging arrangement i

Line Follower Robot Our Line Follower Robot Line followers are one of the most prominent kinds of robots. They have existed for a very long time, however, the technologies used for building them have changed rapidly. Earlier, controller boards the size of bricks were used, but now they have shrunk and become tremendously powerful. Now, technology allows you to build a line follower in just under 10 minutes if you have the parts for it. So enjoy building this quick and easy line follower. Have fun with this DIY hacking tutorial! Required Materials Hardware : 1. Arduino / Arduino Clone or make your own custom Arduino board . 2. Two continuous rotation servo motors like this: Continuous rotation servo . 3. A ball caster: Ball caster . 4. An infrared sensor array like this: Pololu QTR-8A IR sensor array OR a set of six IR Leds and Detectors . 5. Resistors: 1K and 10K . 6. Two robot wheels , select wheels after chec
