Technology used
Intelligent Robotic Arm.
In this project we have designed an automated tool called an
intelligent robotic arm shows more impact on the areas which
are not reachable and manageable by the human being with
the help of Interactive Machines whose body languages are the
replicas of human being. The ultimate aim of this project is
to pick and place the object which will be in any process.
The robot will have efficient arm which will be driven by the
stepper motor which is under the control of microcontroller. VB
used at Front End.

Implementation of Routing Information Protocol (RIP).
(Software Only)
The Internet is a very large network where millions of
computer systems are inter-connected. In this the IP protocol
operates at layer 3 and takes care of end-end routing of
packets. This is done by employing devices called Routers.
Routers all over, whether inside an autonomous system or
outside have to exchange information about the routes known
to them with their neighbors and eventually construct the so
called Routing Table. The RIP is one of the early routing
protocols, implemented in TCP/IP. It is simple, most
fundamental and is used to route the packets inside an
Autonomous system. This project is an attempt towards the
study, analysis of RIP. Implementation of Distance-vector
algorithm used in RIP to calculate the shortest routes.
Implementing the RIP updating algorithm which explains how
a new update is to be processed by the router, how the realtime data is packetized and sent over IP. The pros and cons
of the RIP protocol, improvements made in the new version.

Design of Sample & Hold Circuit at Higher Range Frequencies.
In this project we have designed a Sample & Hold Circuit with
MOSFET as a switch that operates at few Hundredths of MHz.
Sample-and-Hold (S/H) circuits track an analog signal, and
when given a ‘‘hold’’ command they hold the value of the input
signal at the instant when the ‘‘hold’’ command was issued,
thereby serving as an analog storage device. An ideal S/H
circuits would be able to track any kind of input signal, and
upon being given a hold command store at its output, without
delay, the precise value of the signal, and maintain this value
indefinitely. Unfortunately, ideal S/H circuits do not yet exist,
and to be able to pick a S/H Circuit to suit a particular
application. In this application, we discussed the significance of
the various specifications for S/H circuits, and how the
performance is influenced by the circuits.

Solar Panel Maximum Power Point Tracking System.
The Project “Solar Panel Maximum Power Point Tracking
System”, is a photovoltaic system that uses the photovoltaic
array as a source of electrical power supply and since every
photovoltaic (PV) array has an optimum operating point, called
the maximum power point, which varies depending on cell
temperature, the isolation level and array voltage. A maximum
power point tracker (MPPT) is needed to operate the PV array
at its maximum power point.
The objective of this project is to compute MPPT
systematically using a circuit that is a type of perturbation &
Observation method, which is designed to operate under
continuous conduction mode.
A general framework for designing current-mode analog
multiplier circuits based on the Gilbert gain cell is presented for
both BJTs and MOSFETs.
In this project, a new maximum power point tracking
algorithm for photovoltaic arrays is proposed. The algorithm
detects the maximum power point of the PV. The computed
maximum power is used as a reference value (set point) of the
control system. The circuit designed so as to control the
operation of a Buck chopper such that the PV module always
operates at its maximum power computed from the MPPT
algorithm.
