PE1 KNOWLEDGE AND SKILL BASE
PE1.1 Comprehensive, theory-
based understanding of the
underpinning natural and
physical sciences and the
engineering fundamentals
applicable to the engineering
discipline
I attempted to develop a new type
of the robotic arm that can be
applicable in the agriculture
industry.
I designed the system to meet the
requirements of providing real-
time data on hazardous
environment monitoring
parameters and remote controlled.
I suggested the entire team
for the delivery of a project
that could allow the control
of the home appliances
using the TV remote as it is
widely available.

specifications and hence, there is
the need of a MPA robot that is
nothing but a multipurpose
agricultural robot.
We used eZ430-RF2500 as the
wireless development tool for the
CC2500 circuit including
hardware and software those were
required for the development of
this system.
I controlled and used the
RMS voltage adjustments
for controlling the speed or
intensity of the load and
controlled them using the
triac circuitry through
manipulating the firing
angle.

development and research
directions within the engineering
discipline
I was responsible for supervising
the entire project growth with an
assurance that the entire project
objectives can met through
everyone’s contribution in the
project.
I used the “DC/DC buck
converters offer over 95%
efficiency over a wide battery
voltage range, even with input
voltage down to 1.8 volts
extending battery life.
I managed to divide the
project into eight major
components including
power supply, RD232
driver, IR receiver circuit,
zero crossing detector,
intensity regulation in
relation to the main voltage
variation, IR decoder, Triac
firing pulse generation and
TRIAC.

agricultural arm through
combining the serial and parallel
mechanism.
I was the one who has to lead the
team and thus, topic selection was
one of my concern and so, I
suggested to target the industry
related safety and control.
I kept the project simple
and related every activity
with other for the
management and delivery
of the project objectives.

System Architecture and design of
the Virtual Instrumentation
Software and assigned different
individuals with different sectors.
I programmed and managed the
microcontrollers, IR receiver, and
circuit of the entire system.

freedom in manner to widen the
workspace.
I was involved in the Virtual
Instrumentation Software I had to
develop the system in the lab
VIEW software. I had to configure
the schedule of the lab VIEW and
I kept them at the default state
with low observation frequency.
I also considered the other
team members’
association, contribution,
and their comfort
throughout the project for
assuring that the project
could be managed
smoothly

PE2.2 Fluent application of
engineering techniques, tools and
resources
I identified that the prototype
designing will be crucial for the
project growth and every team
member was responsible for the
three different sectors including
hybrid robot system consist of the
“end-effector, a serial last joint
mounted on a parallel manipulator,
a parallel manipulator, a base joint
for rotating a parallel manipulator
and a robot controller.”

I identified that the guarantee of
maximum time among the
transmissions needed to be
managed in a manner that it
guarantees the specified output.
I was totally focused
towards my technical and
management of the entire
project and so, I followed
proper document related
jobs for tracking all the
ongoing activities in
manner to keep a
comparison or baseline of
the project.

PE2.3 Application of systematic
engineering synthesis and design
processes
I also did the Inverse Kinematics
calculation for the different
constructions of the robot.
I used the RF timer that was
efficient and effective in
guaranteeing the maximum time
among transmissions. Again, the
power consumption was the
identified issues through ought the
project lifecycle.
I used the general principle
of the power controlling
through the application of

the electronic knowledge
and made sure that the
expected operations could
be delivered in an efficient
and effective way.
PE2.4 Application of systematic
approaches to the conduct and
management of engineering
projects
I was also appointed for the team
management and assure that every
othe team members are
progressing the project in the
expected way.
I limited the schedules that helped
in reducing the power
consumption in transmission and
reading of the proposed system
and it helped in providing a
reliable keep-alive system.
I used the following block
diagram for the
development of the path
that could possibly be
helpful and effective in
motivating the employees
towards the final delivery
of the project

details that can allow to develop a
new set of plan in manner to make
sure that every individual in the
projecct deliver their setor of the
job in much efficient and effective
manner.
I identified that the reading routine
should be capable of managing the
wide range of the wireless sensors
and must be capable of reading the
different types of the output.
I used IC6, 20-pin
microcontroller AT89C2051
in manner to allow the
system to receive the

that helped in restricting and
limiting the influence of the
variable load applied.
I identified that the multisensory
signals collected from the
hazardous environment have been
extremely small such as in
microvolt or mini volt range, and
for every signal, it has its own

main loop module is responsible
for initializing the configuration
parameters and managing the low-
consumption dynamic schedule for
sensor reading and wireless
communication.
I used it considering the
supply to the triac, as it is
an AC signal and will
