- 1. GALGOTIAS COLLEGE OF ENGINEERING & TECHNOLOGY In the partial fulfillment for the award of the degree of BACHOLERS IN TECHNOLOGY DEPARTMENT AT ELECTRONICS & INSTRUMENTATION ENGINEERING SEMINAR PRESENTATION ON OBSTACLE AVOIDANCE ROBOT BASED ON EMBEDDED SYESTEM SUBMITTED BY : SYED WASI ABBAS B.TECH 3RD YEAR (E.I. A) ROLL NO. : 1209732903 SUPERVISED BY : Mr. GULSHAN KR. DUBEY Session : 2013-2014
- 2. Introduction Design & Development of Obstacle Avoidance Robot Study of Obstacle sensors Working of microcontroller & Motors Advantages, Disadvantages & Applications Acknowledgement & References
- 3. The aim of this project to avoid any obstacle or object in front of robot and automatically change its path. If there is no objects or obstacles then robot continuously go forward. In this project we are using IR sensor pair (infrared transmitter and infrared receiver) . When any object comes in front of robot then IR sensor detects its presence and send signal to the microcontroller. Now the microcontroller controls the movement of dc motors which are connected to microcontroller i.e. robot change its path according to the presence and position of obstacles.

- 7. Interfacing circuit of Robot
- 9. The obstacle senor is used to avoid the robot from the clash to any external devices (or) that is like walls, any obstacle which comes in its way. Here we are using the IR communications .the transmitter and the receiver parts. The transmitter produces the IR rays and they are received by the receiver section

- 12. The name "H-Bridge" is derived from the actual shape of the switching circuit which controls the motion of the motor. It is also known as "Full Bridge". Basically there are four switching elements in the H-Bridge as shown in the figure below.

- 14. An actuator which converts electrical signal into rotation
- 15. We all know that AC motors are normally constant speed motors. Variable speed ac drives uses very complex circuitry because the ac motor speed is varied by the frequency variation and is not quite easy. Stepper motor gives calculated angle of rotation they take number of steps in one revolution they cannot be stopped in between the step. Also they are not constant running motors their use is limited to the area where you want calculated steps to be taken such as printers, plotters, and other similar applications.
- 16. Dc motors are widely used in industry where wide range of variable speed is required. High starting torque & easy speed variations are some of the other characteristics of DC motors.
- 17. Advantages & Disadvantages of obstacle avoidance robot
- 18. Advantages : Whenever robot senses any obstacle automatically diverts its position to left or right and follows the path without human guidance. The programming of the microcontroller is easy. It is a low cost circuit. Disadvantages : It is time consuming project. It is use for short distance only. It is not recommended to keep the range very long because this would cause the ROBOT to keep moving forward and backward as it senses any obstacle, even far away from it. It is not in human control
- 19. Obstacle sensing robot can be applied at the toys where small children will play. It can used for the army application. We can apply number pairs of IR pairs for the safe direction control of the robot. In Mines.
- 20. We can extend this project with wireless technology by IR (or) RF. This robot can be used for pick and place the required object by giving directions to the robot but IR pair should be replaced depending upon the application. By doing extra things, it can be use in Army application.
