#RoboCup2024 – every day digest: 21 July

A break in play throughout a Small Dimension League match.

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

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

Timothy, the educational chief of the workforce 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 workforce 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 exhibits you the place the robots suppose 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 predict 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 dwell on the sphere because the robots are shifting.”

The workforce has been demonstrating the system to the league on the occasion, with very constructive suggestions. Actually, 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 acquired numerous concepts and strategies from the opposite groups for additional developments. This is without doubt one of the first (if not, the primary) AR system to be trialled throughout the competitors, and first time it has been used within the Customary Platform League. I used to be fortunate sufficient to get a demo from Tom and it positively added a brand new stage to the viewing expertise. Will probably be very fascinating to see how the system evolves.

From the principle 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 among the groups which have been utilizing machine studying fashions to help their robots. RoboCupJunior is a contest for varsity kids, and is break 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 obstacles on uneven terrain. There are three totally different strands to the league: 1) Rescue Line, the place robots comply with a black line which leads them to a sufferer, 2) Rescue Maze, the place robots want to analyze a maze and determine victims, 3) Rescue Simulation, which is a simulated model of the maze competitors.

Workforce 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 photos. Additionally competing within the Rescue Line occasion had been Workforce Overengeniering2. Additionally they used YOLO v8 neural networks, on this case for 2 parts 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.

Workforce Tanorobo! had been participating within the maze competitors. Additionally they used a machine studying mannequin for sufferer detection, coaching on 3000 images for every kind of sufferer (these are denoted by totally different letters within the maze). Additionally they took images of partitions and obstacles, to keep away from mis-classification. Workforce New Aje had 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 value, which they will swap between relying on the place (and complexity) within the maze during which they’re positioned.

I met two of the groups who had not too long ago offered within the OnStage occasion. Workforce Medic’s efficiency was primarily based on a medical situation, with the workforce together with two machine studying parts. The primary being voice recognition, for communication with the “affected person” robots, and the second being picture recognition to categorise x-rays. Workforce 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 search 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 world was packed to the rafters with crowds wanting to see the motion.
Standing room solely to see the Grownup Dimension Humanoids.

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

The grand finale featured the winners of the Center Dimension 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.
