LINE FOLLOWING ROBOT WITH GRIPPER

Robotics is a branch of engineering that involves the conception, design, manufacture, and operation of robot.

A robot is a mechanical intelligent agent which can perform tasks on its own, or with guidance.

ROBOTICS- AN INTRODUCTION

Robotics technology is a growing industry which creates high-tech jobs.

Robotics technologies are helping to improve healthcare, national defence, energy, manufacturing, logistics, transportation, agriculture, education, consumer goods, and many other sectors.

Robotics provides an exciting, hands-on way for students to learn Science, Technology, Engineering, and Math.

WHY ROBOTICS?

The line follower is a self operating robot that detects and follows a line that is drawn on the floor. The path consists of a black line on a white surface .

It continuously corrects itself to stay on the track.It is an automated robot which doesn't require any

human help to control it.

LINE FOLLOWER ROBOT

Automated cars running on roads with embedded magnets

Guidance system for industrial robots moving on shop floor etc.

Industrial robot to pickup objects and transfer them to a specific point.

PRACTICAL USES

The IR sensor detects the light emitted by the transmitter, if the receiver receives light, the wheel of that side will keep on moving, as soon as the receiver stops receiving the light (black colour absorbs the light and thus no light is reflected so receiver cannot receive any light) the wheel of that side will stop.

For turning ,the robot stops 1 motor and runs the second to make the turn possible.

For eg: If the robot has to turn right then the motor on right

side will stop and left motor will keep on running and thus allowing the robot to turn.

WORKING

Processing system acts as the Brain of robot, which generates desired output for corresponding inputs. For that we use microcontrollers. I used ATmega8L microcontroller in my robot. It is an ATMEL product. It is also called AVR.

PROCESSING SYSTEM

An infrared sensor is an electronic device that transmit (white) and receive (black) infrared radiation in order to sense some aspect of its surroundings. Infrared sensors can measure the heat of an object, as well as detect motion. The function of infrared sensor in the robot is corrected move on the route when the routes are curved.

IR SENSOR

For moving a robot we have dc motor to attached to wheels gears.

why dc motors DC motors are most easy to control. One dc motor

requires only two signals to perform operation . If we want to change its direction just reverse the polarity of power supply across it. We can vary the speed of motor by varying the supply across it.

Use of gears The dc motor don’t have a enough torque to drive the

robot directly by connecting wheels in it. The gears used to increase the torque of dc motor on expese of its speed.

MOTOR OUTPUT SYSTEM

“DEFLECTION CONTROL STATEMENT”, helping the robot to control the deflections to stay on the path.

Four wheel drive (4WD) , the robot is using 4 wheels , each controlled separately by DC motors attached to them.

The robot has a “GRIPPER” which can lift light weight objects.

“ARTIFICIAL INTELLIGENCE” is used, so that the robot can turn (after end of track) and return to its initial point .
