The main aim of this project is to design Obstacle Detecting Autonomous Robot using Ultrasonic Detectors.
The purpose of the project is to detect an obstacle in the path of the robot using Ultrasonic Detectors and to avoid the collision of the obstacles.
Now a day's every system is automated in order to face new challenges. In the present days Automated systems have less manual operations, flexibility, reliability and accurate. Due to this demand every field prefers automated control systems.
Especially in the field of electronics automated systems are giving good performance. In the present scenario of war situations, unmanned systems plays very important role to minimize human losses. So this robot is very useful to do operations like obstacle Evidence .
Here is an automated unmanned system being designed around a microcontroller which selects by changing its path whenever any obstacle is detected.
According to this project, a robot is designed which is made to move all the time. Apart from this, the system also embedded with ULTRASONIC detectors used to detect the obstacle during which the direction of the robot is changed.
All the devices such as ULTRASONIC detectors, motor by which robot is made to move are being interfaced to microcontroller which forms the control unit of the project.
In the standby mode the robot is moved here and there. Whenever any obstacle is being detected by the ULTRASONIC detectors, the same is sensed and is intimated to the microcontroller. Now the micro controller changes the direction of the robot by driving the motors in a respective direction.
This project finds its place in places where one wants to make the unmanned system with some intelligence
Ultrasonic detectors (also known as transceivers when they both send and receive) work on a principle similar to radar or sonar which evaluate attributes of a target by interpreting the echoes from radio or sound waves respectively.
Ultrasonic detectors generate high frequency sound waves and evaluate the echo which is received back by the detectors. Detectors calculate the time interval between sending the signal and receiving the echo to determine the distance to an object.
This technology can be used for measuring: wind speed and direction (anemometer), fullness of a tank and speed through air or water. For measuring speed or direction a device uses multiple detectors and calculates the speed from the relative distances to particulates in the air or water.
To measure the amount of liquid in a tank, the detector measures the distance to the surface of the fluid. Further applications include humidifiers, sonar, medical ultrasonography burglar alarms and non-destructive testing According to this project we can implement a robot, which detect the obstacles on its way and collision with other obstacles.
