CENTER OF EXCELLENCE


ELECTRONIC SENSOR BASED FLAWLESS PATH FINDER (PROJECT II)



In today’s world robotics is a fast growing and interesting field. Autonomous Intelligent Robots are robots that can perform desired tasks in unstructured environments without continuous human guidance. The project is designed to build an obstacle avoidance robotic vehicle using ultrasonic sensors. The robot is made using ultrasonic sensor and it is controlled by Arduino micro controller. The data is taken from the surroundings through mounted sensors. The sensor can sense the obstacle and deviate its path to choose an obstacle free path. The data is sent to the controller which then decides its movements. We have programmed the controller with ANDROID app.Computational intelligence involves the programmed instructions.



SPECIALITIES OF ULTRASOUND TECHNOLOGY

ELECTRONIC SENSOR BASED FLAWLESS PATH FINDER
INVENTED BY:- ANDHYA GUPTA (EC)

The ultrasonic sensor is one of the best technique which is used to sense the obstacles. The Ultrasonic sensor module “HC-SR04” works on “Echo” concept which is something you get when sound reflects back after reaches the surface. The travelling time of ultrasonic waves is 343m/s. This much of speed is meticulous for MCU’s in microcontroller to measure accurately. Practically the waves reflect back from the surface located 4 meters away in 15 ns. The ultrasonic wave does not affect the humans. The ultrasonic sensor is mostly used for distance measurement application. These sensors are able to detect the barriers present in front of them. Ultrasonic sensors generate sound waves with higher frequencies that humans cannot perceive, making them ideal for quiet environments. They do not consume much electricity, are simple in design, and are relatively inexpensive.
