Putting our lab’s technology to practical use. KOEI Dream Works, a manufacturer of robots, launches a service for its pipe exploration robot, “PIPE-KUN”.

KOEI Dream Works Co Ltd. has put into pratical use of the “Articulated Inspection Robot – AIRo”, developed by the Bioinspired Intelligent Mechatronics Laboratory, Department of Robotics, College of Science and Engineering, Ritsumeikan University, and made it into a pipe exploration robot “Pipe-kun” in October 2020. The service has started in full swing from October 14th (Wed) (* quote from below).

A lab experience for lower-division students 2020!

We held a lab experience for lower-division students on October 29, 2020!

Due to the influence of the new coronavirus, the implementation was canceled in the previous semester. However, there were still students who applied, and although it was a little late, we were able to take it in this way  to prevent the infection ( in order to reduce the risk of virus, we take measures such as disinfection, ventilation, and the minimum number of people required).

We introduced our laboratory (main research topics, seminars, events, job hunting, etc.), explained the principle and mechanism of the snake-robot’s movement, and implementation of control programming. She asked a lot of questions, so we had a good time.


The followings are the impressions of Ms. Y who came to the laboratory experience.

“First of all, I would like to thank you for this opportunity to meet with you, even though the new coronavirus has prevented us from being able to hold face-to-face classes at the university. I had only a vague idea of what a laboratory was, so I was happy to get to know the atmosphere and characteristics of it. I hadn’t had much opportunity to interact with graduate students before, so I learned a lot from my seniors and it made me reconsider what I am doing now.

I also had an exciting time learning things about the content of the research that I didn’t know or could not understand from the leaflet alone. Throughout my studies and student life, I wanted to understand my own characteristics and use this experience to help me choose a laboratory. I would also like to make a clear choice about whether to go on to graduate school or find a job.”

News about the best student paper from RCAR 2020 conference

From September 28 to 29, “2020 IEEE International Conference on Real-time Computing and Robotics (IEEE RCAR 2020) was held online. Mr. SUN Haonan (D2) from our lab gave a presentation with the following topic:

Haonan Sun, Yang Tian, Shugen Ma and Shuya Inoue, Evaluation of Energy Efficiency of an Eccentric Paddle Mechanism on Sandy Terrain

On the conference, Mr. SUN received several constructive and valuable comments from other researchers, which would definitely provide important references for further study. Fortunately, the submission also has been selected as the winner of the “Best Student Paper” award.

ROBOMECH2020 was held from May 27th to 29th, 2020, and eight members from our laboratory have made poster presentations.

Due to COVID-19, this was the first time the event was held online. We used chatting and web conferencing services to present and communicate with each other while viewing the uploaded posters.

ROBOMECH has always been in a poster presentation style where the presenters can interact with each other actively, and the online session was no different. We had a very good experience with sharp questions and advices. In addition, the online form also had extra advantage that allowed us to view the posters easily, regardless of the location or exhibition time.

It was a pity that we were not able to post photos of ROBOMECH this year as we have done in previous years, because the event was not held onsite. However, we did feel the bustle of ROBOMECH even though it was held online.

EcoPro 2019 in Tokyo

EcoPro 2019 was held at Big Sight in Tokyo from December 5 to 7, 2019!

This event was held so that many people could know that companies, universities and local organizations are working to achieve the Sustainable Development Goals (SDGs) adopted at the UN Summit.

At this exhibition, 100 studies from Ritsumeikan University were chosen as SDGs initiatives, and 11 special exhibitions were introduced and demonstrated at the booth.

Lecturer Kakogawa (currently at Kawamura Lab), Oka (D1), Kushiya (M1), Sera (M1) and Ota (B4) from our lab participated in this exhibition, and exhibited an in-pipe inspection robot.

In addition, a workshop for elementary and junior high school students was also held, and lecturer Kakogawa explained the snake-type robots to the children who came.


Prof. Fan and Associate Prof. Qu from Beihang University visited our university

On December 2, 2019, Prof. Shangchun Fan and Associate Prof. Xiaolei Qu from Beihang University (China) visited our university and gave us a lecture about their research activities in Advanced Sensing Technology Lab.

In addition, they visited our lab after the lecture, and we had in-depth exchanges after the introduction of the research activities in our lab.
