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.
