Hello, this is Yuri Makada from the Hakusanroku Office. This time, I would like to write about the Engineering Design IIB final presentation held on Tuesday, January 28th, 2025.

 The Engineering Design IIB class, worked on problem-solving projects on the social, natural, and industrial environments of the HAKUSANROKU (Foothills of Mt. Hakusan) region. Students were divided into two teams, the Agribusiness Team and the Tech Team. I will introduce the activities that both teams have been working on.

Activities of the Agribusiness Team

 The Agribusiness Team has been working on regional revitalization activities in HAKUSANROKU, including the Asagimadara (Chestnut Tiger Butterfly) marking event, roasted Kosen Beniharuka sweet potato sales, and traditional Ningyo Joruri (Puppet Theater).

Asagimadara (Chestnut Tiger Butterfly) Marking Event

 In a fallow field in front of the Hakusanroku campus, Fujibakama flowers (boneset) are being cultivated to attract Asagimadara. The Agribusiness Team is working on a project to revitalize the community by making the migrating Asagimadara a valuable local resource.
 This year, the Asagimadara Marking Event, organized by the Oguchi Community Development Council, the Hakusanroku Satoyama Revitalization Council, and the Asagimadara Fan Club, was held again. The Agribusiness Team participated in the event in a supporting role. The marking experience was limited to 30 participants by advance reservation, and in addition to assisting with the marking activity, the students planned events to ensure that the 30 participants could have a fuller experience. Their goal was to promote the charm of HAKUSANROKU while creating an opportunity for interaction between local residents and visitors.
 To attract participants to the event, the students created promotional posters for the Asagimadara Marking Event and displayed them at Hakusan Himenoyu Onsen, Oguchi Community Center and Sena Roadside Station. 
 Additionally, they set up photo spots, observation areas, and rest areas, in order to promote the event on social media. They also organized various activities such as selling Asagimadara-themed merchandise, hosting a keychain-making experience using a laser cutter, and setting up a capsule toy machine. The capsule toy machine, in particular, was more popular than expected and made many visitors happy.

Kosen Beniharuka Sweet Potatoes Sales

 The Agribusiness Team, with the cooperation of the Hakusanroku Satoyama Revitalization Council, has been cultivating Kosen Beniharuka sweet potatoes since first semester, utilizing a fallow field in front of the Hakusanroku campus. The students collaborated with the Kijitora Coffee Laboratory and Sena Road Station, aimed at revitalizing the local community by selling Kosen Beniharuka sweet potatoes that the students grew by themselves.

 This year, as part of a collaboration with ICT, Kijitora Coffee Laboratory sold "Chips Benya Soft" and "Benya Soft" made with Kosen Beniharuka sweet potatoes, while Sena Road Station offered "Beniharuka Sundae" and fresh Kosen Beniharuka sweet potatoes for sale. 

 Additionally, on Sunday, November 3rd and Monday, November 4th, 2024, the Agribusiness Team sold roasted Kosen Beniharuka sweet potatoes at the Sena Road Station store. Last year, with the aim of promoting the Kosen Beniharuka brand and building a fan base, original merchandise such as keychains and magnets featuring four mascot characters of Kosen Beniharuka were created. These were distributed for free as capsule toys to customers who purchased roasted Kosen Beniharuka sweet potatoes of a certain amount. This year, while inheriting the character goods created by last year's students, new acrylic standing figures were added to the collection.
 This year, the Kosen Beniharuka sweet potato harvest was excellent, with the harvest volume approximately 1.6 times greater than last year. As a result, more Kosen Beniharuka sweet potatoes had to be sold. To promote the brand more widely and boost sales at both the Kijitora Coffee Laboratory and Sena Road Station, a campaign was implemented. Customers who purchased a certain amount of Kosen Beniharuka related products at each store were given a free exchange voucher for a capsule toy.

 Last year, about 30 capsule toys were distributed, but this year, thanks to the many customers who visited the roasted Kosen Beniharuka sweet potato stand from the Kijitora Coffee Laboratory and Sena Road Station, 100 capsule toys were given out. Some customers even returned to buy other products just to get another capsule toy. Others, continuing from last year, mentioned, "We came to enjoy Kosen Beniharuka roasted sweet potatoes again this year." Ultimately, the sales were approximately 1.4 times higher than last year, and the students were able to achieve their goal of surpassing last year's sales.

Ningyo Joruri (Puppet Theater)

 The Higashi Futakuchi Bunya Ningyo Joruri is a traditional form of puppet theater that draws from the Joruri and Bunyabushi, which were popular before the emergence of Bunraku (puppetry). Currently, there are only four places in Japan where Bunyabushi is still being preserved, one of which exists in the Higashi futakuchi area of Hakusan City, Ishikawa Prefecture. 350 years ago, local residents went to Kyoto, studied Ningyo Joruri and brought it back to HAKUSANROKU. Even today, it remains much the same as it was back then.
 With the goal of introducing this unique cultural heritage to more people and providing an opportunity for them to enjoy it, the Agribusiness Team visited the Higashi futakuchi Local History Museum, the venue for the Ningyo Joruri performances. Through interviews with them, they gathered impressions and identified challenges, using these insights to further their activities.

 

Ningyo Joruri paper crafts

 The students planned two events to help promote and revitalize the Ningyo Joruri tradition.
 The first aimed to show the appeal of Ningyo Joruri through the use of paper crafts. Students proposed offering papercraft models as souvenirs for visitors attending performances and making them available for download on a website, allowing people to enjoy them at home.
 The second initiative involved expanding the distribution of promotional flyers beyond public facilities in Hakusan City and promoting the event through posters. As a result, flyers could also be distributed at Sena Road Station and the Ichirino area, which attract many tourists during the winter season for winter sports. Additionally, based on discussions with members of the preservation society, the students created a Current Status Analysis Map, summarizing the ongoing efforts to preserve and promote the tradition.

 In this activity, students explored new experience possibilities with paper crafts and visualized the current state of Higashi Futakuchi Bunya Ningyo Joruri, and I believe that students were able to create opportunities for themselves to become aware of issues from a variety of perspectives. Although it was difficult to secure sufficient time for this activity at the end of the semester, students felt it was important to work together with the preservation society to think about the future of the project.

Activities of the Tech Team

 The Tech Team is engaged in technological development focused on utilizing AI and IoT for wildlife monitoring and notification systems, as well as controlling drones to deter harmful animals as part of pest control measures.
 In HAKUSANROKU, damage to crops by monkeys has become increasingly severe each year. To address this issue, the Tech Team has improved the accuracy of an AI-powered monkey surveillance system to over 90%, developed a function that sends notifications to farmers via LINE when monkeys are detected, and tested the effectiveness of drones in deterring them.
 This year, the team was divided into three groups to explore new ways to protect farmland: the Rover Team, which developed a patrol robot capable of navigating rough terrain; the Drone Team, which tested the precision of automatic takeoff and landing for drones; and the IoT Team, which developed a system to monitor rainfall and wind speed for drone operation.

Rover Team

 Newly active this year, the Rover Team worked to develop a rover that could patrol the farmland in bad weather and intimidate monkeys when drones are unable to fly because of weather conditions. The final goal is to have a rover move around the farmland automatically, but the first step is to develop a rover that can move around the uneven terrain of the farmland. The students proceeded with a detailed design based on their ideas of “what kind of rover” they wanted, such as how fast they wanted the rover to move around the field and how big and heavy they wanted it to be.
 The completed rover was to be tested on farmland, but the farmland was covered with snow, so the test was conducted on campus over concrete, asphalt, and grass with a light dusting of snow on campus.
 How to intimidate monkeys and how to automate the rover to travel over farmland are the next challenges.

Drone Team

 The goals of the Drone Team this year were to investigate the accuracy of a drone’s GPS takeoff and landing and confirmation of system operation. Furthermore, the drone storage box was made and installed on the farmland to enable takeoff, landing, and storage of the drone.

The operation of the developed system is as follows.
1. When the AI monkey detection system recognizes the monkeys, a notification is sent to the user via LINE.
2. The user remotely opens the door of the drone storage box.
3. Under user remote control, the drone automatically takes off and circles the farmland to intimidate the monkeys.
4. After the drone circles the farmland, the drone lands on the storage box.
5. The user remotely closes the door of the storage box.

 The confirmation tests were conducted on campus and confirmed the drone’s takeoff and landing accuracy. The drone storage box was controlled remotely from the cafeteria.

IoT Team

 The IoT Team is the bridge link between the user, the AI monkey detection system, and the drone or rover. When the system detects the monkeys in the farmland, the system sends information such as rainfall, windspeed, and images of the monkey to the user, and the user decides if the drone or rover is ready to operate in the farmland. These enhancements help robots avoid making decisions too quickly. Additionally, for quick maintenance, the software has also been improved to check if the system is offline, whether the internet is connected, and which camera is offline.
