INTRODUCTION ❖Robotics is a part of today’s communication. In today’s world ROBOTICS is fast growing and interesting field. ❖An obstacle avoiding robot is an intelligence device, which can automatically sense and overcome obstacles on its path. ❖Obstacle avoiding is a robotic discipline with the objective of moving vehicles on the basis of the sensorial information..

WORKING OF ULTRASONIC SENSOR.

PREVIEW.

WORKING ❖ The obstacle avoidance robotic vehicle uses ultrasonic sensors for its movement. Movement is done by voice command. ❖ The motors are connected through motor driver IC to Arduino. The ultrasonic sensor is attached in front of robot. ❖ Whenever the robot is going on the desired path the ultrasonic sensor transmits the ultrasonic waves continously from its sensor head. ❖ Whenever the obstacle comes ahead of it the ultrasonic waves are reflected back from an object and that information is passed to the arduino uno..

❖ The arduino controls the motors left, right, back, front, based on ultrasonic signals. In order to control the speed of each motor pulse width modulation is used [PWM]. ❖ when ultrasonic sensor detect the object which is kept inside the path it will send the signal towards the arduino uno and according to that it will rotate the motor..

SOFTWARE USED TO RUN THIS ROBOT.

PRINCIPLE In this project, the vehicle uses the ultrasonic sensor to detect objects. Initially the system starts with one sensor i.e ultrasonic. Robot is designed in such a way that it detects the obstacle inside a particular range. It sends the command to the microcontroller, based on the received input signal, directs the robot to push in an alternative direction by actuating the motors that are interfaced with it via motor driver..

START Connect to bluetooth in mobile Connect the bluetooth of robot Arduino and driver recieves signals Send messages to move Ultrasonic sensors and servo motor activated Messages to go left,right,forw and,back Movement of car Avoiding obstacles STOP.

APPLICATIONS ❖ Automatic change over’s of traffic signals. ❖Counting instruments access switches parking meters especially military applications. ❖In robotics, Arduino is primarily used to control motors sensors and actuators. ❖ Motors are used to drive the movement of the robot and can be controlled with the arduino PWM [pulse width modulation] signals..

ADVANTAGES ❖ The main advantage of this project is that it can detect and avoid obstacles. ❖ Collisions or accidents without disturbing it’s work. ❖ It will make higher efficiency in traffic. ❖ It helps in identifying the hidden dangers of blind spot. ❖The sensory technology can precieve the environment better than the human senses. The robotic cars can sense farther ahead. ❖They can see better in poor visibility. They can detect smaller and more subtle obstacles and they can reduce traffic accidents. ❖ We can make fire detecting Arduino robot or vacuum cleaner by Arduino..

CONCLUSION Almost all navigation robot demands some sort of obstacle detection, hence the obstacle avoidance strategy is of most importance. Obstacle avoidance robot has vast field of applications. Equally they have great importance in science exploration and emergency rescue, there may be places that are dangerous for human or even impossible for human to reach directly then we should use robots to help us. The intergration of voice recognization system in robotic vehicle help disabled people. The speech control system, though quite simple, shows the ability to apply speech recoganization techniques to control the application..

The methods provides real-time operation, in this system android application is used to recognize human voice and is coverted to texts, the text is further processed and used to control the robotics movements. During the project, the complete working of Arduino UNO and a variety of sensors is executed and understood. Coding and designing skills from the base are utilized in the project. The project gives profound knowledge into different advancements and devices for improvement of the venture. Exposure to various software such as Arduino IDE and proteus widened the knowledge in a broad aspects. There is much scope of improvement in the communication range and considerable reduction in processing time..

THANK YOU SO MUCH FOR VISITING.
