RoboCup 2021 OC has selected https://underline.io/ to provide the central services for RoboCup 2021.
All central events appear on the Main Stage, which is denoted by a star in the navigation menu. These events include the opening ceremony, final games in each league (if possible), the Junior and Major award ceremonies, all presentations of the symposium.
For each of the 15 RoboCup leagues (12 Major and 3 Junior leagues) a so-called discussion room will be provided. The activities in each league are all in parallel, like parallel sessions in a conference. They can be found in the navigation menu by the microphone symbol as well as by the schedule symbol.
The leagues can provide the input to each of their rooms in different ways, e.g., as Youtube streaming or as Zoom video conference. The room itself outputs a video and audio stream that can be received all over the world (including China and Iran). Each league room also has a chat function.
Underline has high flexibility to adapt to different needs of the league organizers. But the needs and options need to be discussed in advance to be able to account for them.
In case the plan for a league has already been worked out completely, it can be figured out, how to just best plug this into Underline's platform.
In case a league is still exploring options, we encourage them to explore these directly with Underline.
