Abstract
The Real Time Robot Control by Motion Capture project aims to develop a robotic system
that uses Motion Capture to control movement and to create robot with structure and joints
that move similarly to human. To build this robot control system, the important steps are 1.
Motion Capture using MediaPipe to coordinate body parts and to calculate angle value to
send angle value to servo. 2. Sending angle value to servo by using Pyfirmata library to
command Arduino Uno R3 to control servo rotation. When testing, Motion Capture was
found to be able to locate points on the body and measure the exact angle of the desired point.
But the rotation of servo is still stuck a little bit. Due to the real-time processing, the data
cannot be processed in time according to the operator's movements. Another reason is that
Motion Capture's mis-prediction of organ coordinates affects the angle and rotation of the
servo. However, if this project can be developed further and can be applied to various things,
it will make the robot control more convenient and everyone can access to the robot control.

Abstract
Developing a Prototype Remotely Artificial hand Project is intended to be used as a
prototype to build remotely controlled mechanical hands. For use in medical or other fields,
the mechanical hand will have an anatomical appearance like a human hand. To make it
possible to use and feel close to the real hand, the prosthetic hand can move from a distance.
Through the control of the movement of the user's hand at the computer screen. To pick up
objects that are cylindrical and spherical from the experimental results, it was found that the
spherical object picking test by the mechanical prototype can be seen that out of a total of
100 picking tests, the mechanical prototype was able to successfully pick up a spherical
object 58 times and fail 42 times. To figure out the efficiency, it can be seen that the picking
efficiency of the cylindrical object of the mechanical prototype is 58%, and the hand-holding
test of the cylindrical object by the mechanical prototype can be seen that out of a total of
100 picking tests, the prototype The mechanical hand was able to successfully pick up a
cylindrical object 80 times and fail another 20 times. Taking this data into the calculation of
efficiency, the handling efficiency of the mechanical hand prototype was 80%.

Abstract
Nowadays, there are approximately 388 thousand people with hearing and interpretive
disabilities in Thailand and the trend is increasing continuously. On the other hand, the
number of sign language interpreters in Thailand is insufficient to a critical level. Therefore,
communicating with others for these people is much more difficult because they cannot
communicate by talking or receiving messages by listening. Thus, the project organizers are
interested in developing a sign language translator program that can detect and classify sign
language gestures in Real-time. Starting from 23 sign language gestures that are frequently
used in daily life, we collected data from 5 student volunteers, then apply the data to labeling
objects, data augmentation, and finally, the data was used to train the YOLOv4-tiny 256
models in CiRA CORE. When each model was tested for accuracy, we found that the
accuracy of YOLOv4-tiny 256 is 78.478% ±29.834%.

Abstract
In current society, people do not understand the differences in the personality of others,
resulting in misunderstandings and confusion in the way of other life. Furthermore, some
people are unable to realize which areas of work they have the most outstanding potential.
As a result, they choose a career that is not suitable for their own aptitude. Therefore, it is a
need for a tool for guiding them to know their outstanding potential and select the right
career. The objectives of this project were 1) to develop a game based on the Myers-Briggs
Type Indicator (MBTI) for assessing people's identity, thoughts, and decisions to recommend
a suitable career and 2) to evaluate the satisfaction of gamers. The sample group used in this
study was 24 students in grade 10 of Princess Chulabhorn Science High School Chiang Rai
in the academic year 2021. The mean and standard deviation measures are used to assess
game satisfaction. The results indicated that the score of satisfaction with the game content,
the game system, and the usefulness of the game are 84.61, 77.69, and 90.00 respectively.
This game is helpful in making career decisions and understanding the personality diversity
of others.

Abstract
Currently, there are 391,785 hearing-impaired people in Thailand, representing 18.87% of all
disabled people in Thailand. It is another group of people with communication disabilities,
which is a foundation ability that is important for everyday life in society because the hearing
impaired need to use sign language to communicate with others. In contrast, the language that
people commonly use is spoken language. Consequently, it is difficult for the average person
to communicate with a hearing-impaired person resulting in considerable difficulty in contact
and assistance. Appropriately, people with disabilities receive information from others to be
deprived of various opportunities in life, including some rights that should be received, and
may not be granted. The authors, therefore, have an idea to apply hand position detection
technology alongside the Hidden Markov Model algorithm to translate sign language into
spoken language. The results of the translation will be displayed in the application on the
computer for smooth sign language translation. It can also be worn in everyday life, leading to
applications to facilitate communication with the hearing impaired, resulting in the hearing-
impaired access to more information and to be able to talk and communicate effectively in
daily life with an 81.67% words translation accuracy and 58% sentence translation accuracy.
Much more development is needed for the glove to make the glove with high precision that can
be used in everyday life.

Abstract
Video games are one of the important entertainment mediums. There are many devices to use
to play video games. One of them is a joystick. Generally, joysticks are designed to be used
with two hands. As a result, it cannot be operated with one hand to its full potential. Therefore,
a joystick operated with just one hand was invented. The purpose of this project was to 1) test
the efficiency of one-handed joysticks and 2) study the satisfaction of using one-handed
joysticks among the volunteers. The operation was divided into two parts as follows: Part 1)
Invent a joystick. It will have a one-handed joystick in the shape of a box, with 12 switch
buttons arranged in 3 rows, with two-wheel buttons on the left and under the box, and some
legs help to balance at the back. The primary material is ABS plastic, mainly coded from the
library Gamepad.h. Part 2) Testing the joystick's performance and satisfaction, it was found
that the joystick had an average delay time of about 35.97 ms. with a standard deviation of
2.58, a mean accuracy of 100 percent, and overall average satisfaction on all sides of about
4.33, or is in a good range, with a standard deviation of 0.52. Most volunteers who tested the
joystick said that the device's size is fixed, so people with a hand that does not fit the device
cannot use a joystick to its full potential. In addition, the device is designed to be suitable for
use with the right hand. It makes people who primarily use their left hand not good at it.
Nevertheless, it is generally said to be practical, and if taken seriously, it can be used almost
identically to a two-handed joystick.

Abstract
There are many delicate steps in caring for babies. New parents may not be able to take care
of their children entirely. For example, managing the time needed to care for the baby, such
as eating time and bedtime, is essential in the early stages for the baby to grow into a healthy
child. Therefore, the organisers invented and created an application to help schedule planning
for baby care by bringing information about the baby's daily routine in general. A collection
of developmental photographs and recommendations, including the number of vaccinations
required under the age of 1, are included in the application by bringing the information to
the Glide app website and organising the window of information on child care to be
appropriate, clear, and beautiful to use for ease of use and easy to save data.

Abstract
In Japan, a current disturbing issue is the killing of many pets due to an increasing number
of owners who decide to give up their pets. This is occurring because some owners are unable
to take care of their pets throughout their lifespan due to unavoidable circumstances, and also
because some people obtain their pets to relieve themselves from loneliness due to causes
such as the COVID-19 pandemic, without understanding what is required as a pet owner. To
solve this problem, we propose an application that enables users to experience a simulation
of owning a pet, using XR (cross reality), artificial intelligence, and web-based AR
technology. In this project, we focus on cats, which are particularly the targets that are being
killed. The AR process displays a virtual cat and simulates the troubles that a cat can make,
such as knocking over flowerpots or tampering with human food. Then, a pop-up window
displays the appropriate responses that should be taken by the owner. Through this
simulation, people can understand the important points of actually taking care of a cat, and
can prepare for owning a cat with a firm resolve. The effectiveness of this application will
be evaluated by people who have experience in owning cats. We hope that this pet ownership
simulation will provide sufficient understanding of owning and taking care of a cat in
advance, and will encourage people to raise their pets with responsibility.

Abstract
Amyotrophic Lateral Sclerosis is a symptom of muscle weakness where the patient is unable
to control the movements of the body or other organs as much. At present, there is no cure
for this disease. One of the initial relief and treatment of this symptom is physical therapy.
Therefore, this project aims to design and create tools that will assist in additional physical
therapy for patients with weak arm muscles by using 3D design and printing technology. The
operations are as follows, 1. Design the structure of the equipment and various parts with
Tinkercad 3D design program and design acrylic sheets that have to cut with the RDWork
program. 2. Print finished items with a Fused Deposition Modeling 3D printer and cut acrylic
sheets with the Carbon dioxide Laser Cutting machine. 3. Assemble all parts and acrylic
sheets with ball bearing and servo motor. 4. Place the circuit board and upload the instruction
set to Arduino to control the servo motor, the motor controls the rotation of the hand pad
through a gear. 5. Evaluate the servo capability through trial and timing, then test the tool
with ourselves. It was found that the rehabilitative tool for muscle weakness in arms can be
created with a 3D design and printing program. It supports the arm of weakness muscle
patient quite well. Gears are support each other very well, allows the hand pad to rotate
easily. And the tool can help perform additional physical therapy as designed.

Abstract
Evaporative dry eye disease is decreased tear production or increased tear evaporation
because of meibomian gland dysfunction (MGD), the sebaceous gland under the eyelid.
Severe dry eyes can substantially lead to eye infection and inflammation, abrasion of the
corneal surface, cataracts, and even vision loss. Traditional treatments, such as artificial tears,
warm compresses, and medications, have many limitations. Intense pulsed light (IPL)
therapy is a new treatment for evaporative dry eye disease patients. IPL exposes the light
energy to the eyelid, and the light energy will be absorbed and converted to heat generation
in the specific area. A suitable amount of heat energy will help the function of the meibomian
glands. In the treatment process, the skin color affects the light absorbable, affecting the
treatment's effectiveness. However, the eye is a complex and sensitive organ, experimental-
based studies are complicated and very limited. Therefore, numerical simulation studies are
necessary to determine the optimal condition of treatment. This study developed a numerical
model of dry eye treatment with IPL. The mathematical model was developed based on the
bioheat equation and determined the heat from IPL by Beer lambert law. The coupled
nonlinear set of these equations is solved using the finite element method (FEM). The
influence of skin color intensity will be the parameters in this study that will present the
temperature distribution during the treatment process. The results of this study can be used
as fundamental knowledge of the dry eye treatment with IPL and guidelines for practical
treatment design.

Abstract
" imake!" is a virtual experience project to promote interest in makeup regardless of gender.
Target users, including women as well as men, can discover the beauty of a made-up face by
checking make-up images onto their faces. To realize the make components in the ICT
system, we originally prepared, eyebrow, mascara, eye shadow and eyeliner in the RGBA
formatted png files. Those parts are arranged to the coordinates of facial feature points.
System provides suitable makeup image in different mode considering users requirement.
First, one of the main functions is the "Simple Mode," which allows the user to select a
makeup image from a typical makeup template. The second is the "Diagnostic Mode," which
uses image recognition and several questions to select the makeup image that best suits the
user. The diagnostic method was created by integrating image recognition and other
information in a unique way. Other modes include "Practice Mode," "Event Mode," and
"Custom Mode," which allow users to select and experience their favorite makeup from
multiple types for each makeup part. The final real-time image is presented on the screen of
laptop in real time after the makeup is applied. This allows each user to discover the
possibilities of enhancing their own facial beauty. We will also users actually use this system
and improve the functions based on their feedback.

Abstract
“SEE-DRO FIGHT!" is a project for exercise using drones. The players will be split into two
roles. One will be the pilot who flies the drone, and one will exercise with the markers as the
escapees. The drone operates by following markers. Points are awarded by pressing a button
with markers in a certain area of the drone's field of view. The pilot gets points for pressing
a button while keeping the makers within range of the drone’s view. The player who earns
more points wins. The drone is controlled by transmitting information entered by the player
using an input device to the drone. Computer is acquired the video transmitted from the
drone. And computer checks if the makers are within the defined range of the drone's view.
Also, the player can operate the drone while viewing the video from the drone. Since real
drones are used in the competition, players and not players can enjoy feeling the power of
the drone in front of them. And we can see how escapees escape. So, who are not players in
the game can enjoy watching the game on-site.

Abstract
Periodic Table Game is an educational game that promotes the learning of Chemistry courses
in a multimedia format. Idea of the game comes from a problem that is often found in
chemistry classes is forgetting the group of elements, so this game was develop for anybody
who want to learn and memorize chemical element symbols, atomic numbers, and atomic
masses playfully. This project is suitable for people of all ages. It was developed with Unity
Game Engine, the language used to create this game is C#. The way to play this game is very
simple. Initially, you have to select the element you want to answer. After that, you have to
choose the correct group, mass number and atomic number of that element and if your choice
is correct, your opponent will be attacked. If any part of the answer is wrong, it will show
the answer after that round. The game continues like this until one side has 0 Life Points.
The results recorded by our game testers show that most users enjoy the game and make the
periodic table more memorable for them. We also have some systems in development to
make the game even more different in the future.

Abstract
We are developing a system called "iMake!" that allows users to easily apply makeup by
projecting an image of the makeup onto their faces using a projector. One of the functions of
this system is to project the makeup image of an event onto the face. There are few
opportunities to wear special makeup such as Japanese Kabuki, but this project allows anyone
to feel like a Kabuki actor by projecting that makeup on their face, and thus experiencing a
variety of cultures. The system consists of a DepthAI camera, a physical button, a Jetson Nano,
and a small projector, and can be easily installed using these small pieces of equipment. The
projection is done by creating a Delaunay diagram from the face images acquired by the
camera, performing an affine transformation on the corresponding face positions, and pasting
it onto the projector. The face coordinates used to create the Delaunay diagram are obtained
from an ML solution called Media Pipe provided by Google. The system also has a high degree
of freedom, cleverly handling the HSV color space and implementing a mechanism to change
the color of the makeup. We also plan to make functional improvements based on user
feedback. The results of these improvements will be reported, including a demonstration at the
event.

Abstract
LightsOut is a puzzle game in which you try to turn off all the switches, or “lights”, that are
arranged in an n×n grid. The rule is that when you click on a cell, the cell along with each of
its immediate neighbors switch from “on” to “off”, or “off” to “on”. The goal of our study is
to establish a method to find the optimal solution (with the smallest number of moves) to any
LightsOut game, especially ones with some lights erased from the beginning, or “Holey
LightsOut.” To achieve this goal, we first devised a method to determine whether a LightsOut
game is soluble. Examination of invariants in soluble and insoluble games proved that if the
number of “on” switches placed in specific cells on a 4×4 or 5×5 grid is the determinant; if it
is an even number, the game is soluble, and if it is an odd number, the game is insoluble. Our
present challenges is to generalize this solubility test to games of n×n grids or to those of Holey
LightsOut with a view to establishing a method to find the optimal solution.

Abstract
Virtual reality is gaining popularity, particularly in education and business fields. However,
transition between reality and virtual reality might impair users' recall accuracy, which makes
us doubt using VR would improve our learning or job efficiency. Our study aims to determine
whether the transition impacts users' memory and to discover techniques to better this
transition. 36 students from Ichikawa Senior High School during the 2022 academic year
participated. Three experiments were conducted in which subjects memorized a series of
words. Each time, subjects were later separated into groups, and changes in the rate of correct
responses from the time the experiment was done under the same conditions were compared.
The first experiment was for verifying the effect of transition on memory accuracy. Conditions
made a small effect on the participants’ scores. The second experiment was for narrowing down
which part of the transition caused the effect. Conditions made a medium effect on the
participants’ scores, and scores taken when divided by conditions were significantly lower than
scores from the baseline experiment. This suggests that VR goggles alone do not cause
significant effects on memory accuracy. The third experiment was for investigating which of
the three transition methods (how the screen switches when putting on and taking off VR
goggles, which were Cut, Fade, or Wipe) had the smallest impact. Conditions made a small
effect on the participants’ scores. These results can help determine where to improve VR
equipment and its content, and can contribute to further social utilizations of VR.

Abstract
The application helping to improve language and communication development of children with
autism aims to help children with autism by improving the language, communication, and
social development of children with autism. and to be on the lookout for potential dangers
while operating the application. Because autism is a unique developmental problem. It clearly
shows that children are unable to develop socially and communication is age appropriate. But
children with autism have feelings like normal children. just unable to express themselves
properly, children also need love, understanding and acceptance like normal children. In
addition, epidemiological research over the past 30 years found that the average prevalence of
autism was 4.8 per 10,000 population, or about 1 per 2,000 population. Found that the
prevalence has increased with up to 1 person per 250 inhabitants. We therefore see the problem
and wants to solve the problem by using the technology that is currently available. Therefore,
a project on application to help promote language and communication development of children
with autism is therefore a total of 4 steps in operation, namely 1) designing the application to
be suitable for making and using. 2) Finding textbooks and making teaching materials for
children with autism especially 3) Programming using Raspberry pi with python language. 4)
The application was tested on children with autism and took a satisfaction test. The application
was tested in a group of children with autism, and it was found that the application improves
language development. and communication of children with autism It can help children with
autism develop language.

Abstract
Shoe boxes ( 桁箱 /getabako/ ) are widely used to keep shoes in Japan. However, using a
box which does not have enough airflow can cause problems such as dampness, mold, and
musty shoes and leads to the box becoming dirty and making an unpleasant smell. For these
reasons, we decided to develop the shoe box to be more useful by adding various functions
including an odor sensor, air flow, sterilization, and deodorants function. The odor sensor
detects the smell by reacting with ammonia and shows the result in a number. If the result is
more than the set value, the red sign will appear and make the sound. Then there is the
sterilization function by using UV light which has a high ability to sterilize bacteria that
cause bad smell and then the deodorant function that spray down the shoe deodorant product.
All sensors and functions of this project are carried out by micro: bit processor. This Smart
Shoe Cleaning Box project was developed with the purpose of making life more convenient.
We no longer have to wash shoes often, we can still use our shoes that look clean and not
emitting unpleasant smells.

Abstract
At present, there are many epidemics. Especially the disease found that various strains of
coronavirus it can live on surfaces like metal, glass and plastic for up to nine days, or nearly
a month in low temperatures or has an appropriate relative humidity as for our house, the
weather is quite hot. The virus can therefore stay on surfaces like paper and coins for less
than 9 days. Therefore, we must prevent the cash that we hold from becoming a medium for
spreading germs. By cleaning cash The organizer has invented smart money sterilizer in
order to clean the money by placing the money holder, the hand will pass through the IR
infrared sensor, causing the circuit to work, then the alcohol will be sprayed out of the water
pump and there will be a fan blowing the money to dry. From the experiment, it was revealed
that the smart money sterilizer can work to disinfect but there are some unstable points. But
still can be used in real life.

Abstract
This project aims to create a usage control system for disabled parking spaces to prevent the
misuse by normal people, causing people with disabilities to be deprived of their parking
rights. We, therefore, proposed a usage control system for disabled parking spaces using a
microcontroller and RFID technology, which can send notifications via the LINE Notify
service. The process starts when a car arrives at the disabled parking space. The ultrasonic
sensor at the disabled parking space will detect the car, and the RFID reader will check
whether the car has the RFID card or not. If the card is detected, the buzzer will not be
activated and no notification will be sent. In another case, if the card is not detected, the
microcontroller will send a signal to the buzzer to sound the alarm and send LINE
notifications to the LINE group of the responsible person to solve the issue. A functional
prototype was created to demonstrate the working principle of the proposed system, which
can perform with a success rate of 99.3%.

Abstract
Infectious diseases represented by COVID-19 can be prevented by ventilation. This study
aims to implement a special IoT (Internet of Things) system to measure and control air
environment at a room using ESP32. ESP32 is a micro controller unit (MCU) with integrated
Wi-Fi. Environmental sensors such as CO2, temperature and humidity are connected to the
MCU to monitor the air environment. This MCU connected to the internet via Wi-Fi has the
ability to send measured data to “Ambient”. Ambient is a cloud service and has the ability
to store the data and display as graphs. The user can check the measured data via the Internet
using a terminal equipped with a WEB browser. Furthermore, in the special IoT system we
developed, the MCU has an infrared communication capability, thus the system can
automatically start and control existing air conditioners and fans that has infrared receiver
based on the set conditions. For example, if the temperature is above 30 degrees, it turns on
the air conditioner automatically. As a result of embedding HTML files in this MCU, air
conditioning can be controlled manually via the Internet. This system can be applied not only
to prevent diseases caused by airborne infections but also heatstroke. This system can convert
existing home appliances to IoT if infrared communication is available, even if they are not
connected to the Internet.

Abstract
The spread of the Covid-19 virus caused many deaths. Because the Covid-19 virus simply
enters the human body by spreading through the air and secretions. It's the main channel
from coughing, sneezing, saliva, and snot. It's not just inhalation that can get you infected. If
a person sneezes or coughs into their hands and then touches things, touching them can also
be a risk of getting infected. Medical personnel are the most at risk of infection from
contacting the patients. The authors, therefore, have an idea to develop a robot to transport
medical supplies in a hospital. Its purpose is to act on behalf of the medical personnel who
are responsible for providing medical supplies to the surgeons and reduce the contact with
patients. The microcontroller-controlled robot performs the task by processing the data from
infrared obstacle avoidance sensors, and an Arduino microcontroller controls the motors for
the robot movement. The robot can move or stop by the medical personnel command.

Abstract
Stair climbing robots are currently needed in various situations and industries. Examples include
disaster relief and transportation industry. At present, the most efficient and mainstream stair
climbing robot is the subcrawler, which is the most cost-effective and problem-solving solution.
However, we could not find a website that provides a series of development procedures for
subcrawler stair-climbing robots so that even non-specialists can easily understand them. Therefore,
we thought that we would support those who need it by actually developing the robot ourselves and
disclosing the process on our website. To develop a subcrawler robot by ourselves, and to publish the
development process on our website. They develop the robot with their own hands, and then publish
the design data they used, as well as the source code, circuit board, wiring, necessary parts, and
processing methods, all in one place.

Abstract
It's nice to see and live in a clean environment but we have a need for more electrical
appliances to meet the needs and increase comfort in daily life, including consumption
behavior patterns according to IT developments by Don’t we know that About 400,000
tonnes of electrical and electronic products were also surveyed and collected data on
consumer behavior in dealing with electrical and electronic products when not in use, most
of which originated from homes. On the other hand, many people throw all Metal and Plastic
in just one trash can leaving the pitiful garbage picker man another work to do and that is to
segregate different kinds of garbage and trashes and to pick out the reusable and recyclable
ones from those electronic products That’s the reason why we studied this project because
of those problems. This project aims to separate different kinds of Metal and Plastic such
as electronic circuit board etc. by just dropping all these trashes and Metal and Plastics to
this one trash can instead of using different trash cans and choose which of those trash cans
we should throw a certain kind of Metal and Plastic. By applying the computer science
investigation, we come up with a conclusion that our Automatic Metal Separator is the
solution to segregate different types of Metal and Plastic

Abstract
Recently, robots have started to be used in public facilities such as train stations. However,
it has a drawback that it cannot move between floors. So, I thought of a solution to this
difficulty. I invented a robot with a second, longer sub-crawler attached to the front, which I
started to make five years ago. By programing the computer that is connected to the robot I
could make the robot climb stairs. This is done by using the second sub-crawler to give the
robot a longer wheelbase. In this way, the robot can smoothly ascend the stairs without
needing to step.

Abstract
Medicine sending machine project was developed with the aim of reducing the burden of
drug picking of pharmacists in pharmacies to be more comfortable by commanding control
from a computer. This project has two major components: 1. System for ordering from a
computer. When the pharmacist wanted to order, the medicine sending machine then
processes the received signal and moves to pick up the medication as directed and place it at
the drug delivery point. 2. Transportation system Once the order has been ordered, the
transport system will start to work. The transport system used with the medicine sending
machine will use the CNC system, which is an automatic machine that works with a
computer system. It has high resolution and precision movement along the X, Y axes. The
system will move according to where the desired drug is contained. Then use the device to
pull. To pull the pills out into the bag After picking up all the pills as ordered, they will bring
all the pills as ordered and deliver them to the desired point. From the actual test results, it
was found that the medicine sending machine can work as designed. And can really help
reduce the burden of pharmacists in drugstores

Creating Remote-Controlled Robotic Fingers Using Arduino

Advisor: Shotaro Baba1

1Tokyo Gakugei University Senior High School

Abstract
Why is it difficult for robots to move with the precision of humans? When I thought about
why humans can make precise movements, I realized that fingers play a very important role.
That is, humans are able to move their fingers very precisely and simultaneously, which
helps us make precise movements. From this fact, it is hypothesized that if I can remotely
control a robot that imitates human fingers, that robot would be able to perform more
complex movements as if it were a human. Therefore, this study aims to use an Arduino, a
small computer-like device, to build a remotely controlled one-finger robot. First, I attach a
part to the finger that quantifies its movement. Each joint is attached to a potentiometer,
which measures the angle of the joint and converts it into a numerical value. The values are
then transmitted remotely to the device. The servo motors connected to the potentiometers
adjust the angles of the joints while bending them. In this way, the robot’s fingers will move
remotely as the human moves their fingers. At this point, I made a prototype robot whose
movement can be transformed into numbers and be transmitted remotely to the device. One
limitation is that there is a time lag because it takes time to remotely send and convert the
signal, which makes the robot movement look less like a human. To solve this problem, I
will improve the transmitter device so that it can send the signal without delay.

Abstract
The smart bed for bed-ridden patients was invented to help take care of and comfort the
patients. It helps caregivers to change the patients’ position to reduce the incidence of
pressure ulcers and facilitate patient care. The smart bed for bed-ridden patients was designed
to have a remote command system via mobile phones. It can check the patient's sleeping
status with a camera and report data through LINE notification. The smart bed for bed-ridden
patients is easy to use. It is robust and made from natural materials. It can check patient’s
status, and report the results by using motors and camera controlled by a Raspberry pi and
programmed in Python. The motors rotate and adjust the bed components so that it can set
up as a backrest, bend at patient’s knees, and tilt left and right. This is to reduce the
occurrences of pressure ulcers. The efficiency of the bed was determined by the speed of
adjusting via buttons and applications. It was found that the standard deviation was 0.023.
Testing the accuracy of the bed adjusting via buttons and the applications, we found that the
bed had the most error of 0.8 degree. Testing the quality of pictures from the bedside camera,
it was found that the best camera distance to the patient is at 20 centimeters, which is equal
to the standard distance both in the light and in the dark. Therefore, it can be concluded that
the smart bed for bed-ridden patients can be used and is effective in reducing pressure ulcers
and giving better care for patients

Abstract
Developed countries around the world are aging, and this will continue to accelerate in the
future. Japan, especially, has the highest elderly population currently with about 30% of the
population being elderly. Japan also has a hot and humid weather every summer. Therefore,
many people suffer from heatstroke every year. More than half of heatstroke patients are
elderly, and these events often occur while they are at home. There are three factors regarding
this problem. First, the temperature and humidity in the rooms of elderly people are too high.
Second, elderly people are often in declining physical health. Third, elderly people don’t
want to turn on their air conditioners. For these reasons, I think that it is necessary to make
cooling equipment, such as air conditioners and electric fans, react automatically to their
environments. The system made in this study consist of three parts. First, a sensor always
monitors the temperature and humidity in the room. Second, a control device processes the
data sent from the sensor and sends a command to the infrared device. Third, an infrared
device emits an infrared signal. By combining these systems, air conditioners can be
controlled according to environmental conditions. If using this system, elderly people could
be saved from dangerous environmental conditions. This can also protect elderly people
without needing a caregiver, reducing the burden on caregivers. I want to prevent elderly
people from dying of heatstroke, and I hope, through this research, that elderly people can
live healthier and longer lives.
