ABSTRACT
Whiteboards
are well-known medium that provide a convenient surface upon which notes,
drawings, charts or other hand-written notations may be made. Whiteboards are
often used in group discussions. As with traditional chalkboards, whiteboards allow
notations to be made in multiple colors. Like the chalkboards, the various
hand-written notations made on whiteboards are erasable by the manual
manipulation of an eraser and our team attempted to make a prototype of an
electrical automated white board eraser, which would be convenient most of the
times. This study includes a system that is automatically commanded by simple
switch buttons. The evaluation instrument used was adopted from the
Technological University of the Philippines standard evaluation instrument,
using a 5-point numerical rating for the prototype’s aesthetic value,
functionality, workability and general acceptability. The product rating scores
followed were: 5.0excellent, 4.0-very good, 3.0-good, 2.0 fair and 1.0-poor and
the point scale for each criterion was adjectively interpreted as follows: 4.5
– 5.0 = excellent, 3.5 – 4.4 = very good, 2.5 – 3.4 = good, 1.5 – 2.4 = fair,
0.5 – 1.4 = poor. The findings were accompanied also by the comments and
suggestions of the evaluators for further improvement of the developed
prototype. With the cited criteria for evaluation of prototypes, the Exercise
Gadget and Charging Unit got an over-all mean rating of 4.0 which means, “Very
good”. One evaluator cited that it will help a lot the operators of repairs
shop, since most of them are applying the laborious manual methods. Highest
score was obtained under workability (4.27) and durability and safety (4.23),
because the evaluators have observed by themselves the acceptability of the
development prototype. This study based on the evaluation and the activities
done, has the following conclusion: (1) an Automated White Board Eraser can be
made from the available materials in the province, like those that can be
recovered from the junk shops. The rest of its parts can be fabricated in the
College’s Shop Laboratories, (2) the Automated White Board Eraser was found
acceptable to the people who evaluated it, thus given adjectival rating of
“very good” and, (3) the prototype is deemed useful in the shop and the college
building, which can be used also at home, offices and anywhere needed.

CHAPTER ONE
INTRODUCTION
1.1 Background
of the Study
Automation describes a wide range of technologies that
reduce human intervention in processes. Human intervention is reduced by
predetermining decision criteria, sub process relationships, and related actions
and embodying those predeterminations in machines. (https://en.wikipedia.org/wiki/Automation
)
A whiteboard also
known by the terms marker board, dry-erase board, dry-wipe board, and pen-board is any glossy, usually white surface for nonpermanent
markings. Whiteboards are analogous to chalkboards, allowing rapid marking and erasing of markings on their surface.
The popularity of whiteboards increased rapidly in the mid-1990s and they have
become a fixture in many offices, meeting rooms, school classrooms, and other
work environments Patrick (2015)
The term whiteboard is also used metaphorically to refer
to features of computer software applications that simulate whiteboards. Such
"virtual whiteboards" allow one or more people to write or draw
images on a simulated canvas. This is a common feature of many virtual meeting, collaboration, and instant messaging applications. The term whiteboard is also used to refer to interactive whiteboards. John
Lionel Tagle (2016)
There are currently two different accounts of
the history of the whiteboard, one from the US and one from the UK and both
dating to the late 50s early 60s.The first version has the white board invented
by Martin Heit, a photographer and Korean War veteran. The idea was originally
developed for having next to a wall phone to take messages down on.
We made this prototype to help on making
easier way and less time consuming in erasing whiteboard markers. http://www.ijlret.com/Papers/Vol-2-issue-12/4-B2016445.pdf
The first whiteboards were very
expensive and were made of enameled steel. Cheaper alternatives have since made
their way into the market, including laminated chipboard, high pressure
laminates and steel boards with a white, usually polyester or acrylic, coating.
Enameled whiteboards, also referred to as porcelain, or sometimes even glass
boards, remain the highest quality boards available though, since the
alternatives all have a tendency to leave residue of erased markings on and in
the surface and are difficult to keep clean after a short while. Hard baked
vitreous enamel is so non-porous that marker ink does not penetrate the surface
and these boards remain erasable indefinitely if not scratched. Due to the
price difference the cheaper alternatives now have the largest market share in
the office products market, but in more demanding environments, such as
schools, universities, etc. porcelain boards remain the gold standard. https://www.researchgate.net/publication/322357266_Automatic_Whiteboard_Cleaner_Using_Microcontroller_Based_Rack_and_Pinion_Mechanism
Broadly speaking, the invention relates
to techniques for automated erasure of non-permanent markings from boards, such
as whiteboards. The invention can be implemented in numerous ways, including as
a method, system, apparatus, and computer readable medium. As a system for
automatic erasure of a board, one embodiment of the invention includes at
least: an eraser member for use in erasing non-permanent markings on the board,
a support means for supporting the eraser member against the board when erasing
at least a portion of the non-permanent markings from the board; and a motor
operatively connected to the support means to drive the eraser member across
the board while the support means supports the eraser member against the board.
Joseph (2017)
The system is designed to save a lot of time and unnecessary
effort needed in cleaning boards.
It is designed to clean boards in a less than half the time required to clean
the blackboard/whiteboard by a human (nevonprojects.com)
1.2 Statement of Problem
To
design and develop a board cleaning system which can overcome the problems
related to chalk dust, discomfort for the teacher and wastage of time while
erasing the board.
1.3 Aim of the Study
This project is mainly focused on making
a prototype that will help on making an easier way and less time consuming in
erasing whiteboards markings.
To create an electromechanical system
that automates the eraser function for the whiteboard, saving time and effort
in class.
1.4 Significance
of the study
·
As a method for automatically erasing a
board, one embodiment of the invention includes the acts of: receiving a user
request to erase non-permanent markings on the board; activating a motor to
drive an eraser strip across the board after the user request has been
received; determining whether erasure of the board is completed; deactivating
the motor to cease driving eraser strip across the board once the determining
determines that the erasure of the board is completed https://www.academia.edu/

1.5 Scope of the Study
This
study is only limited on some particular commands on the control system.
Implementation of safety covers over mechanical parts is absent. Sourcing of AC
power integration for motors is also needed. More easily accessible eraser
replacement/rail Maintenance is also considerable.
Design
of cheaper rail-running wheels wills also a concern. For extra harsh board surfaces,
implementation of cleaning solution spray nozzle or vibrating eraser through
controller implementation of harmonic excitation for future development. The study is limited only on design development,
fabrication and assembling and evaluation of the finished product or prototype
by selected evaluators.
