I am Michihiro Hayashi, a faculty advisor for the KOSEN Robocon (KOSEN Robot Contest) team. The National Competition of the KOSEN Robocon was held on Sunday, November 16th, 2025, at Ryogoku Kokugikan. Team A of ICT, mainly composed of students from Kanazawa Campus, participated in the event. This was ICT’s first appearance at the national competition in three years, since 2022.

KOSEN Robocon features a different theme every year, requiring teams to design and build new robots from scratch between the theme announcement in mid-April and the regional competition in early October. This year’s theme was “Great High Gate,” where robots had to stack cardboard boxes to create a gate and pull a cart carrying a team member through it. The higher the gate, the higher the score. At the Tokai-Hokuriku regional competition, ICT’s team “Koubako Club” won the Technical Award and advanced to the national competition via the judges’ recommendation.

For more information about the regional competition, please see the article [NHK KOSEN Robocon 2025, Tokai-Hokuriku Regional Competition].

After the regional competition, we worked on improving the robot for the nationals. First, we increased its travel speed by replacing gears and sprockets in the drive mechanism, achieving about 1.7 times faster movement. We also upgraded the claw mechanism for gripping boxes and fine-tuned the control program, doubling its speed. However, the faster movement made operation more challenging, and the student in charge of driving the robot struggled at first. To overcome this, we practiced not only on the Kanazawa campus but also at YUMEKOBO — a makerspace for students to freely create and experiment— simulating real match conditions until the operator became more comfortable with the controls.

At Ryogoku Kokugikan, the venue for the national competition, robots had to be transported between inspection areas, test runs, and waiting zones without elevators, requiring significant manpower. We asked two 5th year students who participated last year to help. Thanks to their willingness, we were able to attend the national competition as a six-member team.

In the tournament, we faced Hiroshima KOSEN’s “Itsukushima” in the first round and won 290–10. In the second round, we lost to Akashi KOSEN’s “Stackmate” 250–375. The Akashi team advanced further but was defeated by the eventual champion from Asahikawa KOSEN in the semifinals.

Roles at the national competition differed slightly from the regional event, so we asked each member for their thoughts.

Comments from Team A Members:

[Haruki Ota]
　

As the team leader and the operator, I found controlling the faster robot challenging. In the first match, I made a slight mistake with left and right, but overall, I managed to control the robot without any major errors.

 

 

[Haruto Shiraishi]
I was responsible for situational judgment and giving movement instructions. Using my experience as the operator in the regional tournament, I could make accurate decisions and guide the robot effectively.

 

 

 

[Imaru Oishi]
　

I continued riding the cart at nationals. My costume was upgraded with an original apron, giving me a market vendor look. I was happy to show off smooth movements without spinning around like some other team’s robots.

 

 

[Shiyu Sano]
Known as “Prayer Shiyu” from the regional broadcast ending scene, I handled robot maintenance in the pit. With almost no opportunity for test runs at nationals, every adjustment and check required intense focus.

 

 

 

[Ryuto Hashiya]
I assisted in transporting robots and tools inside the venue. My experience from last year’s regional competition was helpful. Sharing meals with teammates in Ryogoku was also a great memory.

[Sansar Sergelen]
I helped in the pit and set up gates during the preparation time. Thanks to my height, I could place the topmost box on the gate. The yakitori in Ryogoku was delicious!

We plan to continue participating in KOSEN Robocon in the coming years. I hope that seeing the seniors’ efforts will inspire younger students to join.

 

 Hello, this is Ayane ito, a 2nd year student. Let me begin with a quick question — have you ever heard of DMG MORI?
 In short, DMG MORI is one of Japan’s leading machine tool manufacturers with a strong global presence. My name is Ayane Ito. I am a 2nd year student, and during the summer vacation, I participated in the Digital Manufacturing Hands-on Seminar hosted by DMG MORI during this summer break. I would like to share what the experience was like.

 First, a brief introduction to DMG MORI. As mentioned above, it is a major manufacturer of machine tools, and many of you may already be familiar with the name. The company designs and produces tools such as Numerical Control lathes, 5-axis machining centers, and milling machines, which are used worldwide thanks to their outstanding practicality and precision.
 The Digital Manufacturing Hands-on Seminar organized by DMG MORI offers participants the opportunity to learn about the latest machine tools and automation systems. The program is open to technical college students and includes both online lectures and a two-day in-person practical session. Participants can observe real, working industrial machines up close — close enough to touch them. For me, the highlight of the program was being able to operate the machines myself.

The machine we used during the workshop was the 5-axis machining center “DMU50 3rd Generation.”
 It moves the drill and the workpiece along the X, Y, and Z axes, combined with two rotational axes, to create complex shapes with remarkable precision. The drill head moves freely, almost like a robotic arm straight out of a science fiction film. It was incredibly satisfying to see it move precisely to the programmed coordinates and cut the metal exactly as intended.


 As for the automation systems we learned about — I won’t spoil too much here. I highly recommend experiencing it for yourself by joining the Digital Manufacturing Hands-on Seminar. What’s more, participation is free of charge, with transportation and accommodation expenses covered. The seminar is held in various locations across Japan, making it accessible for students nationwide. It is also a valuable opportunity to interact directly with professionals working in the manufacturing industry.

 That concludes my inside report on DMG MORI.

 Thank you for reading, and I look forward to sharing more next time!

I am Michihiro Hayashi, and I serve as a faculty advisor for the KOSEN Robocon (KOSEN Robot Contest) teams.

The Tokai-Hokuriku Regional Competition of the KOSEN Robocon is an annual event in which our students regularly participate, was held on Sunday, October 5th, 2025. This year, we joined the competition with a total of 12 students: four students from Kanazawa Campus as Team A, and eight students from Hakusanroku Campus as Team B.

Each year, the contest features a different theme, requiring teams to design and build entirely new robots between the theme announcement in mid-April and the regional competition in early October. The 2025 theme was “Great High Gate.” Robots were tasked with stacking cardboard boxes to form a gate, through which a cart carrying a team member would be pulled by the robot. The higher the gate, the more points awarded.

Let me introduce the teams and their robots.

Team A: Koubako Club (Kanazawa Campus)

Team A consists of four 4th year students. Their robot was inspired by the local delicacy Koubako-gani (female snow crab), and its role was to transport a pre-assembled gate of stacked boxes to a designated location. We interviewed team leader Haruki Ohta, operator Haruto Shiraishi, cart rider Imaru Oishi, and pit mechanic Shiyu Sano.

Comments from Team A Members:

[Haruki Ohta]
I returned home during summer break to obtain my driver’s license, and I regret not being able to contribute much to the robot’s construction during that time. However, after obtaining my license, I was able to dedicate more time in the second semester and feel I contributed to the team’s success.

 

 

[Haruto Shiraishi]
I was nervous during the match, and my robot operation was a bit shaky at times. Still, we achieved our target score in the first match and won. We’ve been recommended for the national competition, so I’ll continue to give it my all.

 

 

[Imaru Oishi]
I dressed as a seafood shop clerk handling Koubako-gani while riding the cart. Although I’m not skilled in robot design or assembly, my light weight and slender build helped the robot pull the cart and pass through the gate smoothly. I was the one waving to the audience during the exhibition.

 

 

[Shiyu Sano]
I oversaw manufacturing and assembling robot parts. The robot performed smoothly without any malfunctions or damage during the competition. After the matches, I was so exhausted that I fell asleep in the pit area—and was caught on NHK’s camera! I wonder if that footage will be broadcast.

 

 

 

Although Team A was eliminated in the preliminary league with one win and one loss, their robot’s gate transportation function was highly praised, earning them the Technical Award and a spot in the national competition. We hope they continue to excel at the national level.

 

Team B: Hakobou (Hakusanroku Campus)

Team B consists of 1st and 2nd year students. Their robot mimicked the mechanism of a container crane used in port cargo operations. Decorated with black-and-yellow hazard stripes and a red rotating beacon, it embodied the look of a working vehicle. The robot lifted and stacked boxes using a hand that opens and closes like a crane and an extendable arm.
Although eight members participated in the regional competition as per the rules, a total of 11 students were involved in robot development and practice. Even those not selected as players played vital behind-the-scenes roles. We interviewed team leader and operator Kaishu Ishiharada, and support member Akira Terashima.

Comments from Team B Members:

[Kaishu Ishiharada]
This year, we reflected on past experiences and maintained a positive team atmosphere. As a result, we completed the robot earlier than usual and had ample time for practice. I was less nervous during the matches, which I believe contributed to our strong performance (Top 4). I hope to continue working hard with my teammates next year.

 

 

[Akira Terashima]
Although I joined the regional competition as part of the cheering squad, which was a bit disappointing, I had the opportunity to observe many robots from other schools. It was a valuable experience, and I hope to apply what I learned in future competitions.

 

 

 

Team B advanced through the preliminary league undefeated and reached the final tournament. They continued to win until the semifinals, where they narrowly lost to the eventual champion, finishing in the Top 4. Their robot performed consistently and reliably in all matches. Despite the pressure, Team B operated the robot flawlessly, a testament to their thorough preparation.

 

This year, both teams succeeded in getting their robots operational early, allowing for repeated match-style practice. Problems identified during practice were addressed through design improvements and strategic adjustments. These approaches closely align with engineering design principles and could be effectively applied in classroom settings as well.

 Hi, my name is Kotaro Higuchi, a 1st year student at the ICT. Recently, five high school students from the state of Missouri, USA, visited our campus. Today, I would like to share my memories with my buddy, Isaac.

 I first met Isaac on the evening of Saturday, June 7th, 2025, the day they arrived at the Hakusanroku campus. My first impression of him was that he was tall and had such an adult aura, so I couldn’t believe that he is a high school student.  However, when I tried to speak with him, I found out that he was interested in Japanese culture. While we were explaining our school, he listened aggressively and frequently asked questions.

 I was relieved that we were able to become friends so quickly. The next day, we went on a trip to Kanazawa. During the bus ride, Isaac was curious about everything he saw in Japan. He said the rice plants growing in the paddy fields were beautiful and we had an exciting conversation about the differences between school life in Japan and America. In Kanazawa, he was impressed by the clever design of Kanazawa Castle and saying, “This castle must have been really hard to attack.” I thought that was a very interesting and unique observation. At the end of the trip, he became hooked on Japanese food, and he ate Dango and bought lots of Onigiri and snacks at 7-Eleven.

 After that, we spent our weekdays together attending some classes. We also played basketball and American football after school, which made the rest of the time we shared really satisfying. I hope we can meet again someday.

 Hello, this is Yuri Makada from the Hakusanroku Office. This time, I would like to introduce a project created by 1st year student Taiki Sasaki using Autodesk Fusion.

 In the Computer Skills IA course for 1st year students, students begin working with Autodesk Fusion to create 3D models right after entering ICT. In this class, students learn the fundamental computer skills necessary for engineers. Taiki Sasaki, a 1st year student, applied what he learned in class and spent two months creating a 3D model of a V8 engine! I've put together a video showcasing his work—please watch!
