RoboCup 2023: One Week Update
by Nicolai Ommer 24 Jun '23

24 Jun '23

Dear all, As RoboCup is starting in approximately one week (!) we would like to update you on the final topics. Radio Frequency Requirements Please submit your radio frequency requirements <https://forms.gle/SJudXbUZ2wQBA9ND9> by June 28th so that we can assign frequencies to teams and clarify any issues with the LOC. You can have a look at the previous year's assignment <https://docs.google.com/spreadsheets/d/1hRFL8HIk0Z2CVAxTixg-ktKgxDcJ24r7Orh…> to get an idea of what other teams used, but note that there are more teams this year. We’ll do our best to assign frequencies in a fair manner. Tasks for new teams We would like to remind new teams that there are some things you have to do in order to play matches. An overview is given here <https://ssl.robocup.org/joining-the-small-size-league/>. Please make sure you have performed all actions as soon as possible, but at the latest before the competition starts. TC signup The RoboCup Small Size League 2023 Technical Challenges are the Chip Pass Challenge and the Ball Placement Challenge. Please sign up your team to participate in this form <https://forms.gle/dGcoXAeZgxp9XFLA8>. More information about the TC and their rules here <https://ssl.robocup.org/robocup-2023-technical-challenges/>. Deadline is June 28th. Open source submissions The RoboCup Small Size League Open Source Award goes to a team that has demonstrated a commitment to sharing and supporting their software and hardware designs for the benefit and advancement of the RoboCup community. If you would like to take a shot at the award, you have to send an email to the Small Size League Mailing list with the following information: - Link(s) to the open source project - Link(s) to any related documentation for using the open source project - A short description of the project and documentation submitted and their innovation and relevance to the RoboCup Small Size League. The subject of the email should be “RoboCup 2023 - Open Source Award Submission <Your Team Name>”. Late submissions will not be considered. More information about the open source award can be found here <https://ssl.robocup.org/robocup-2023-awards/>. Referee quiz Similar to last year, we have created a referee quiz. This quiz is designed to improve the notoriously poor quality of many of our referees. Each team needs to be able to perform the impartial roles (referee, assistant, game controller operator and vision expert) for matches where they are not playing themselves. Finishing the rules quiz correctly will be necessary for that, and only people who finish the quiz are allowed to perform the impartial roles. Please fill in the quiz before the start of the competition . The quiz contains some open questions. Please try to explain as best as possible how you would handle the described situation. It is to give us an indication of how teams would act. The OC will provide the preferred course of action on the first day of the competition. The quiz can be found here <https://forms.gle/35fJVy49j6QkefEG8>. A useful reference would be the rule book <https://robocup-ssl.github.io/ssl-rules/sslrules.pdf>. ETDP posters All division A teams are required to bring along a poster that illustrates the content of the paper. The poster must be of A0 size and will be hung at the RoboCup venue. Please remember to design and print this poster. Groups We’ve drawn the groups as outlined in our previous email. The results for Division A are: Group A: TIGERs (GermanyA) Robodragons (JapanA) Roboteam-Twente (Netherlands) KIKS (JapanB) Group B: ZJUNlict (ChinaA) SRC (ChinaB) ER-Force (GermanyB) Immortals (Iran) The results for Division B are: Group A: RoboCIn (BrazilA) Ri-one (Japan) The-A-Team (USA) Group B: luhbots-Soccer (Germany) UBC-Thunderbots (Canada) OrcaBOT (Thailand) Group C: RoboIME (BrazilB) RoboJackets (USA) Sysmic-Robotics (Chile) Group D: RoboFEI (BrazilC) NAMEc (France) ITAndroids (BrazilD) And in case ZJUNlict cannot make it to France, the alternative group in Divisions A are: Group A: TIGERs (GermanyA) Roboteam-Twente (Netherlands) Robodragons (JapanA) Dummy2 (Dummy) Group B: ER-Force (GermanyB) SRC (China) KIKS (JapanB) Immortals (Iran) We will decide on which of the Division A groups are used on the 5th, right after the open source presentations, with the information available to TC/OC at that time. Also note that SRC has withdrawn their participation, so the matches against them will be skipped. Reminder: Preference to play with walls Please remember to choose your preference towards playing with walls in this form <https://forms.gle/eeWT9Z8FQBJVaTmH6> (regardless of your preference). So far, 13 teams have voted. We have extended the deadline to June 28th to give the other teams a bit more time. Heads Up: Redesigned Game Controller UI If you have not noticed yet: The UI of the SSL Game Controller has been completely redesigned. We strongly encourage you to have a look and get familiar with it, so that you are not surprised in the first match. https://github.com/RoboCup-SSL/ssl-game-controller See you all in Bordeaux soon!

Wifi spectrum enforcement at RoboCup 2023
by UBC Thunderbots 17 Jun '23

17 Jun '23

Dear OC and TC’s, We hope this email finds you all in good health. We are concerned about the enforcement of 3.2.5 Radio Communication for the Small Size League at Bordeaux this year. Thunderbots communicate with their robots using WiFi and last year, due to the uncontrolled WiFi spectrum at the venue, we encountered significant network congestion and latencies. Despite being assigned a specific WiFi channel we could use at competition, we found that many participants in the competition started WiFi hotspots that occupied our channel. We are wondering and hoping the organizers can implement stricter enforcement of assigned WiFi channels in Bordeaux this year, as it was done in Sydney 2019. This would greatly help our gameplay and naturally be greatly appreciated. Let us know if this is possible and whether there are any planned strategies for the enforcement of WiFi channel assignments this year. Cheers, Yichen Zhou, Team Captain Arun Balumunari, Software Lead --- *UBC Thunderbots* Faculty of Applied Science The University of British Columbia | Vancouver Campus robocup(a)ece.ubc.ca | http://ubcthunderbots.ca/

Tournament structure, group seeding and preference to play with walls
by Tobias Heineken 13 Jun '23

13 Jun '23

Dear SSL-Community, RoboCup 2023 will start in 3 weeks, so we wanted to give you some updates regarding playing with walls and the grouping. Playing with walls This year, we will offer all teams to play their matches with walls. To allow for some preparation, the preference to play with walls can not be changed arbitrarily: We ask all teams to announce their preference till June 23rd (anywhere on earth)through this form <https://forms.gle/eeWT9Z8FQBJVaTmH6>. The responses are published <https://docs.google.com/forms/d/1Kb2voTSFtIJvoxmoRSsCpZO-80mZgIoPBiBJQQCohj…>immediately. The preference is binding for all matches in the group phase. It can be changed once between the group and the elimination phase through this form <https://forms.gle/oNAEMGAjE77TcSCH8>and is then binding for the remaining games. A match is played with walls, if both teams have announced their preference for wall games. Playing with walls underlies the following rule changes: * Rule 6 - Ball Leaves The Field <https://robocup-ssl.github.io/ssl-rules/sslrules.html#_ball_leaves_the_field>does not apply * The field size is increase by the field boundary - ssl-vision will send a Geometry with adjusted field sizes and a boundary width of zero Tournament Structure & Group seeding We have finished the schedule and the seeding for the upcoming Robocup. You can find the schedule at https://docs.google.com/spreadsheets/d/1EUjOuGdRLxptcESywCAKdruRATmy2j6ezu6… <https://docs.google.com/spreadsheets/d/1EUjOuGdRLxptcESywCAKdruRATmy2j6ezu6…>. Division A will play a 8 player competition, with 2 groups of 4 teams each, followed by a double-elimination knockout tournament, similar to the competition in 2019. Compared to 2019, the matches of 'winner of each group against 4th of the other group' are canceled, and the winner of the group is assumed to win this, and the last place of the group is assumed to lose that match. As a result, 1st of each group skips Upper Round 1 / 2 (which now only 2nd vs 3rd each) and starts in the upper semifinals. The 4th of each group starts in the Lower Tournament. Division B will play a 12 player competition, with 4 groups of 3 teams each, followed by a single-elimination knockout tournament. Similar to 2019 and LARC 2022, but different to Robocup 2022 in Bangkok. This also means 90 mins per match in Division B (was 120 mins). This is necessary to accommodate the increased number of participants. Please be prepared that the schedule is going to be tight. As in Division A, the winners of each group get to skip the first round of the knockout stage as a reward for winning their groups. The Repositoryhttps://github.com/RoboCup-SSL/ssl-grouping <https://github.com/RoboCup-SSL/ssl-grouping>is already updated to include the newly seeded teams. As we are going to draw both a two group and a four group competition, I modified the software to first take the number of groups as a first parameter, followed by the two random seeds. We also disabled country locking in Division A (too few distinct countries participating), but enabled it in Division B except for Brazil. So if you're competing in Division B and are from a different country than Brazil, you are promised not to play another team from your country in the group stage. We are going to use the random numbers given by the following link: https://www.random.org/integers/?num=6&min=1&max=123456&col=5&base=10&forma… <https://www.random.org/integers/?num=6&min=1&max=123456&col=5&base=10&forma…> Please note that this link does not work yet (to make sure I didn't pick some random numbers I liked best), because it will use the pre-generated random numbers from 24th of June and will only work on and after 24th of June. As soon as the numbers are available, the link will create 6 numbers. The two most left numbers are going to be used to draw the division A groups (with `ln -f teamsA.txt teams.txt; ./grouping 2 <firstSeed> <secondSeed>`) and the second pair to draw the division B groups (with `ln -f teamsA.txt teams.txt; ./grouping 4 <thirdSeed> <fourthSeed>`). TC/OC has been made aware that both teams from China are currently experiencing visa issues for France. To avoid the issue where the top seed from one of the two divA groups is missing (and the group is as a result much weaker) the third pair will be used to draw groups where ZJU is replaced by a dummy team (in seed 3), ER-Force is moving up to pool 1, and KIKs is moving up to pool 2. If you want to challenge the seeding for the competition, you have to do this before the groups are drawn, i.e. before random.org published the random numbers for the 24th. As the earth is round and time zones are unpredictable, send your complaints on or before 22nd AoE. See you in France!
