Having face-to-face Baka Seminar

Hello everyone !

We had “Baka seminar” (baka means foolish) last Saturday, May27th at BKC campus.

This is Ma lab’s original event where each of us choose our own topic and do research (can be anything foolish) and give presentation. The best awards were given to M2 Ms.Shreni and B4 Mr.Asakura.  Congratulations!!

Finally, after the long COVID restrictions, we were able to get together and enjoy the party.

Graduates joined us and we had a great time in the wonderful weather outside.

Professor Frank C Park’s Special Lecture at BKC Campus

Special lecture by Professor Frank C Park (IEEE RAS President/Professor at Seoul National University) was held at BKC Campus on February 2nd. The title was “Robot Models in the Age of Machine Learning”.
Below is a comment from Mr. LIU Zaiyang(Doctoral student).

Thank you  very much for Prof. Park’s amazing presentation. I learned a lot from this lecture. Firstly, I realized the limitations of the traditional robot model based on kinematics and dynamics. I used to view the two independent problems as being “solved”, but this is far from the case, especially if a robot has a high degree of freedom and the measurements are noisy. Secondly, I know about the underlying geometric properties of robots and the significance of machine learning. This lecture broadened my horizons and made me realize my lack of knowledge. I will continue to work hard to make up for my shortcomings.

IROS2022 Lab tour

After IROS2022, many researchers who participated in the conference came to visit our lab. We introduced various kinds of interesting robots and advanced research developed in our lab. The structures and control methods of robots were explained in detail and their movement was demonstrated.

Below are the questions from researchers who joined the lab tour and the answers from us.

Q1:(Quadruped Robot)How to know the robot is stable when the robot lifts one foot?

A1: The robot is stable when the vertical projection of the center of gravity (COG) remains inside the support polygon formed by the robot’s feet.

Q2:(Gripper)Where does the object “absorbed” by the robot go?

A2: It depends on the application scenarios. For example, the absorbed object will be placed on a conveyor belt in the object transportation scene.

Q3: (Crawler) How does the crawler climb stairs?

A3: It is realized by an underactuated mechanism. When the crawler encounters a step or an obstacle, the rotation movement of the track will be switched to another kind of movement like a lift arm.

Q4: Are all the robots shown in slides developed in this lab?

A4: Yes. More precisely speaking, the original version or idea was derived from Malab. For example, after graduating from Malab, Prof. Kakogawa developed many kinds of pipeline robots with high performance applied in different fields.

IROS 2022 in Kyoto, Japan

Hello everyone, I’m Yiming Cao, a doctor student (D4) in MaLab.

I am one of the onsite participants in the 2022 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS 2022), which has been held in Kyoto, Japan from October 23-27, 2022.

The theme of the conference is “Embodied AI for a Symbiotic Society”. Over 3,800 onsite participants and 873 online participants attended the conference.

As an onsite presenter, I presented my research content at the conference. Personally, it was my first onsite academic presentation. I am pleased that I had the opportunity to communicate with many outstanding researchers face-to-face.

I have given a presentation on the following topic:

Yiming Cao, Longchuan Li, and Shugen Ma, A Creeping Snake-like Robot with Partial Actuation.

During the meeting, I received some constructive and valuable comments from other researchers, which will provide important references for my future research.

What I have learned from the experiences are:

(i)Introduce my research as telling a short story. Basically, the story should cover the motivation (why?), goal (what?), methods (how?), and results (so what?). Thus, while doing the research, I should think of the presentation as a big picture that hooks the viewer, to help people easily understand my work. Meanwhile, keep the story engaging, logical, and accessible.

(ii)Refine the main points while answering a question. Due to the time limitation, I should know how to answer attendee questions concisely and directly.

I am one of the volunteers of IROS 2022.

Due to COVID-19, most of the sessions were hybrid. My partner Mr. Ma Zhenxuan (M1) and I were the staffs in charge of Room 7 (Room E) of the conference. The specific work of us was to ensure that both onsite and online presenters could successfully present their research and discuss with each other.

What I have learned from the experiences are:

  1. When encountering a problem, BE POSITIVE. That means taking problem-solving as a priority and being sedated to deal with problems.
  2. Combine past failure experiences and use divergent thinking to consider problems that we might encounter in advance. The goal is to break big tasks down into details.


I am the MC of the conference event at IROS 2022. My task is to keep an event moving and to introduce contributed chairs to the audience. Thanks to the trust of our Prof. Shugen Ma, I have learned many important abilities to be an MC, such as how to capture and maintain the attention of the guests, and skillfully deal with emergent phenomena.


During the conference, we enjoyed the performance of Wadaiko, which is known as the heartbeat of Japan, as well as the amazing Japanese fireworks, Hanabi.

It’s my great honor to participate in IROS 2022, thanks to Prof. Ma, Prof. Tian, Prof. Li, Prof. Kakogawa, and the kind members in MaLab. I learned a lot from the conference, not only for my research but also for my whole life experience. I’ll keep them in mind and do my best in my future life.


Volunteer of IROS 2022

I am Yang Zhang, a doctoral student in the BioInMech Laboratory of Ritsumeikan University. It is a great honor to be a volunteer of IROS 2022 (Kyoto, 10.23-10.27), which is the first international top-level conference I have attended since I came to Japan, and also my supervisor, Professor Shugen Ma, was the general chair. During this period, I worked with the team to complete the service work conscientiously and successfully. There are some personal experiences.

  1. Gain work skills

Serving international top conferences is a recognized job that helps to gain more experience in the field of robotics. As a volunteer in the Discussion Room, it was a challenge to answer the various questions of the participants in a timely and accurate manner, which improves my ability to quickly find information and express it.


  1. Improve professional skills

The committee provided free participation opportunities for volunteers, allowing me to learn from experts in robotics throughout the conference. By following speeches and exhibitions of interest, I was exposed to new information that prompted me to think in the context of my topic. For example, focusing on the speeches and publications out of interest in topics such as bionic robots, medical robots, and mechanisms.


  1. Networking

The pandemic has made face-to-face communication a luxury, but procedures like antigen testing of IROS 2022 have made it possible. At the meeting, I attended speeches of experts such as Professor Shugen Ma, Professor Paolo Dario, and Professor Nassir Navab. And also talked about research with friends from the UK and other regions. Similar interests, passions, and challenges can unlock many new ideas and opportunities.


  1. Future

Volunteering at the top conference in robotics is an incredible experience and learning opportunity, which is a fond memory. In the future, based on the accumulation of theory and technology, I will actively participate in conferences in the field of robotics, meet friends, and share research!
