2. Introduction Design & Development of ObstacleAvoidance Robot Study of Obstacle sensorsWorking of microcontroller & Motors Advantages, Disadvantages & Applications Acknowledgement & References 3. The aim of this project to avoid any obstacle or object in front of robot andautomatically change its path.If there is no objects or obstacles then robot continuously go forward. In thisproject we are using IR sensor pair (infrared transmitter and infraredreceiver) .When any object comes in front of robot then IR sensor detects its presenceand send signal to the microcontroller. Now the microcontroller controls themovement of dc motors which are connected to microcontroller i.e. robotchange its path according to the presence and position of obstacles. 4. Design andDevelopment ofObstacleAvoidance Robot 5. Interfacingcircuit ofRobot 6. The obstacle senor is used to avoid the robot from the clash toany external devices (or) that is like walls, any obstacle whichcomes in its way. Here we are using the IR communications.the transmitter and the receiver parts. The transmitter producesthe IR rays and they are received by the receiver section 7.

It isalso known as "Full Bridge". Basically there are fourswitching elements in the H-Bridge as shown in the figurebelow. 9.

We all know that ACmotors are normallyconstant speed motors.Variable speed ac drivesuses very complex circuitrybecause the ac motorspeed is varied by thefrequency variation and isnot quite easy.Stepper motor givescalculated angle ofrotation they take numberof steps in one revolutionthey cannot be stopped inbetween the step. Alsothey are not constantrunning motors their useis limited to the area whereyou want calculated stepsto be taken such asprinters, plotters, andother similar applications. 12. Dc motors are widely usedin industry where widerange of variable speed isrequired.High starting torque & easyspeed variations are someof the other characteristicsof DC motors. 13. Advantages &Disadvantagesof obstacleavoidance robot 14. Advantages : Whenever robot senses any obstacle automatically diverts itsposition to left or right and follows the path without humanguidance. 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 thiswould cause the ROBOT to keep moving forward andbackward as it senses any obstacle, even far away from it. It is not in human control 15. Obstacle sensing robot can be applied at the toyswhere small children will play.It can used for the army application.We can apply number pairs of IR pairs for the safedirection control of the robot.In Mines. 16. We can extend this project with wireless technology byIR (or) RF.This robot can be used for pick and place the requiredobject by giving directions to the robot but IR pairshould be replaced depending upon the application.By doing extra things, it can be use in Armyapplication. 17.
