INTRODUCTION

Aimed towards creating PLC controlled

automatic pick and place system.

Controlled by PLC and SCADA .

To enable ease in transporting an item from onplace to other .

Helps in conditions impossible for human to

operate.

Uses a robotic arm that is operated through a DCgeared motor.

Uses SCADA to control and supervise the entire

system.

PROBLEM STATEMENT

Now a days industries demand automated

material handling system where it is nearlyimpossible for human due to hazards

environment and degree of precision

required. Also the cost and efficient working

of a automated system over the human also

contribute o implementation of such system.

SCADA

Supervisory control and data acquisition

Computer system monitoring and controlling a

process.

Most control actions are performed automaticallyby PLC but SCADA provides a overriding or

supervisory level intervention

A SCADA system consists of a number of remote

terminal units (RTUs) collecting field data andsending that data back to a master station

Examples for SCADA soft wares are Citect and

WonderWare

Proposed time taken for arm movement from fully vertical to

fully horizontal position on one side = 10 sec

Arc length created by arm movement circumferentially

=300* pi /2=0.4712m

Speed of lifting=0.4712/10=0.04712m/s

Speed in rpm =

1.642 rpm

Power P= 2* pi *N*T/60=2*1.642*0.1018/60=0.0175W

SCOPE OF THE PROJECT

Geared motors can be replaced by servo

motors for more precise movements. Potentiometers can be replaced with specific

sensors for more accurate sensing.

Grip can provided with a detection sensors fordetection specific objects.

Obstacles can be sensed by proximity sensors.
