On April 25, we showcased our robots at SPEXA (Space Business Expo), held at Tokyo Big Sight (April24-26) , as a member of the Earth & Space Exploration Center, Ritsumeikan (ESEC). Professor Kakogawa delivered a speech during the conference, introducing our In-pipe Inspection Robots and Underwater Exploration Robots. Additionally, three Master’s students participated, presenting their research findings. We are grateful to all who joined us at the conference and showed interest in our booth!
