Obstacle Detector & Find The Way to Reach Destination Robot

Advisor Md. Ataullah Bhuyain Lecturer Dept. of CSE City University

Group Members Khandaker Maria Shabnam Dept of CSE City University

IntroductionAim : To make a robot that avoids obstacles and immediately find it’s own way.

Equipment

Ultrasonic Sensor

 Ultrasonic sensor range is about

10cms

Arduino Uno

● The Arduino Uno is an open source microcontroller board.

BreadBoard

Jumper Wires

► Jumper Wires:

Can fit into Bread Board, Arduino Uno, Servo etc.

► BreadBoardBuilding or prototyping circuits on a breadboard

standard size servo with 3 wires

Servo A Servo is a small device that incorporates:

a two wire DC motor, a gear train

a potentiometeran integrated circuit and an output shaft.

► Of the three wires that stick out from the motor casing,

One is for power,

One is for ground,

& One is for control input line
