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.
