#RoboCup2024 – daily digest: 21 July

A break in play throughout a Small Measurement League match.

At the moment, 21 July, noticed the competitions draw to a detailed in an exhilarating finale. Within the third and remaining of our round-up articles, we offer a flavour of the motion from this final day. When you missed them, you’ll find our first two digests right here: 19 July | 20 July.

My first port of name this morning was the Normal Platform League, the place Dr Timothy Wiley and Tom Ellis from Group RedbackBots, RMIT College, Melbourne, Australia, demonstrated an thrilling development that’s distinctive to their crew. They’ve developed an augmented actuality (AR) system with the purpose of enhancing the understanding and explainability of the on-field motion.

Timothy, the tutorial chief of the crew defined: “What our college students proposed on the finish of final 12 months’s competitors, to make a contribution to the league, was to develop an augmented actuality (AR) visualization of what the league calls the crew communication monitor. It is a piece of software program that will get displayed on the TV screens to the viewers and the referee, and it reveals you the place the robots assume they’re, details about the sport, and the place the ball is. We got down to make an AR system of this as a result of we expect it’s so a lot better to view it overlaid on the sphere. What the AR lets us do is mission all of this info reside on the sphere because the robots are transferring.”

The crew has been demonstrating the system to the league on the occasion, with very optimistic suggestions. The truth is, one of many groups discovered an error of their software program throughout a sport while attempting out the AR system. Tom stated that they’ve obtained loads of concepts and strategies from the opposite groups for additional developments. This is among the first (if not, the primary) AR system to be trialled throughout the competitors, and first time it has been used within the Normal Platform League. I used to be fortunate sufficient to get a demo from Tom and it undoubtedly added a brand new stage to the viewing expertise. Will probably be very attention-grabbing to see how the system evolves.

From the primary soccer space I headed to the RoboCupJunior zone, the place Rui Baptista, an Government Committee member, gave me a tour of the arenas and launched me to a number of the groups which were utilizing machine studying fashions to help their robots. RoboCupJunior is a contest for college kids, and is cut up into three leagues: Soccer, Rescue and OnStage.

I first caught up with 4 groups from the Rescue league. Robots determine “victims” inside re-created catastrophe eventualities, various in complexity from line-following on a flat floor to negotiating paths by way of obstacles on uneven terrain. There are three totally different strands to the league: 1) Rescue Line, the place robots observe a black line which leads them to a sufferer, 2) Rescue Maze, the place robots want to research a maze and determine victims, 3) Rescue Simulation, which is a simulated model of the maze competitors.

Group Skollska Knijgia, participating within the Rescue Line, used a YOLO v8 neural community to detect victims within the evacuation zone. They skilled the community themselves with about 5000 pictures. Additionally competing within the Rescue Line occasion have been Group Overengeniering2. Additionally they used YOLO v8 neural networks, on this case for 2 components of their system. They used the primary mannequin to detect victims within the evacuation zone and to detect the partitions. Their second mannequin is utilized throughout line following, and permits the robotic to detect when the black line (used for almost all of the duty) adjustments to a silver line, which signifies the doorway of the evacuation zone.

Group Tanorobo! have been participating within the maze competitors. Additionally they used a machine studying mannequin for sufferer detection, coaching on 3000 photographs for every kind of sufferer (these are denoted by totally different letters within the maze). Additionally they took photographs of partitions and obstacles, to keep away from mis-classification. Group New Aje have been participating within the simulation contest. They used a graphical consumer interface to coach their machine studying mannequin, and to debug their navigation algorithms. They’ve three totally different algorithms for navigation, with various computational price, which they will swap between relying on the place (and complexity) within the maze during which they’re situated.

I met two of the groups who had lately introduced within the OnStage occasion. Group Medic’s efficiency was based mostly on a medical situation, with the crew together with two machine studying components. The primary being voice recognition, for communication with the “affected person” robots, and the second being picture recognition to categorise x-rays. Group Jam Session’s robotic reads in American signal language symbols and makes use of them to play a piano. They used the MediaPipe detection algorithm to seek out totally different factors on the hand, and random forest classifiers to find out which image was being displayed.

Subsequent cease was the humanoid league the place the ultimate match was in progress. The sector was packed to the rafters with crowds desperate to see the motion.
Standing room solely to see the Grownup Measurement Humanoids.

The finals continued with the Center Measurement League, with the house crew Tech United Eindhoven beating BigHeroX by a convincing 6-1 scoreline. You may watch the livestream of the ultimate day’s motion here.

The grand finale featured the winners of the Center Measurement League (Tech United Eindhoven) towards 5 RoboCup trustees. The people ran out 5-2 winners, their superior passing and motion an excessive amount of for Tech United.
