Dear Robocup teams,

The TC has been in discussion for a few months now on the rulebook for Robocup 2023. We have decided to change the format of the competition. In previous years teams were allowed to choose which challenges they participated in in a given timeslot. This year we will revert to the format of 2017 where we have set challenges in each timeslot. This means some challenges will no longer be part of the league. We understand that this is a major change so below we will provide our reasoning. Having teams choose their own challenges meant that teams could focus on their own strengths. However over the past couple of years we noticed some drawbacks to this format as well. Teams would choose the challenges where it was easiest to score points and challenges that were difficult but very scientifically interesting would not be chosen as they were too risky. Furthermore it became hard to compare the performance of teams as extra emphasis had to be placed on making sure the points that could be scored had to be ‘balanced’ across challenges. This was already a difficult task but especially when teams can choose their challenges it makes the competition a game of ‘who can score the most points’ rather than ‘whose robot is the best’. With the new format we hope to see teams participate in the same challenges. This makes it easier to align “scoring points” and “the robot being the best”, allowing teams to focus on making the best robot rather than what scores the most points.

The challenges that will be part of the Robocup 2023 tournament:

1. Carry my luggage 2. Receptionist 3. Storing groceries 4. Serve breakfast 5. GPSR 6. Clean the table 7. Restaurant 8. Stickler for the rules 9. EGPSR

The TC may make some more minor changes to these challenges and the final rulebook will be published on March 31st.

Kind regards, the Technical Commission
