I was just typing something similar before I saw your post. I even used the word "flaily". Adding fatigue to the simulation feels like it might have significant impact.

[@budnick1]

Along similar lines, if there was some cost to getting hit, like being slow to move for some time, I wonder if there would be an emergent consensus to avoid causing damage to your opponent, like an emergent moral code. Would they even develop a tit-for-tat rule enforcement?

[@nemonomen3340]

I was also about to say this. It seems to be a commonly overlooked issue when training AIs in movement.

[@maelstrom2313]

They may be moving more efficiently than real football players. People don't always take the most efficient paths when moving, we have to consider extraneous social variables of how our movement looks. It's possible that it takes more energy to restrict the movement of limbs than to incorporate their inertia into the body's trajectory.

[@miladragon]

@@maelstrom2313 if that were the case, real soccer players would move like this. No one cares about looking stupid if they win (cf. the Fosbury flop, which looks stupid but is standard, because it lets you jump higher). There's also no reason to think that these should be moving efficiently, because there's no incentive for them to be doing so (they don't get tired).

I would love to find out with a model like this what the ideal play style would be according to game theory and physical limits of the players, but still having to follow all the rules. For example: Would it actually be better even for the goal keeper to move out and play in the field, vs. staying in the goal? I guess humans didn't figure out optimal gameplay yet for soccer and this could lead to new and crazy strategies.

[@SweBeach2023]

It was my initial thought as well. Using AI we could try so many new strategies. And it wouldn't be hard to give the different AI players different properties to reflect the properties of the real players of a professional team. On eis a faster runner, another have better stamina, a third one have great control of the ball etc.

[@petermoras6893]

I think one of the major improvements in the last few years we've seen in AI training (besides training size/time) is how we train intermediate goals to speed up training. If we simply took the untrained AI with the joint body, and asked them to learn soccer, it would take forever with minimal improvement. But as we've seen in this video, they first train the AI to enable it to walk, dribble, and kick the soccer ball. Once the AI knows how to perform general ball handling tasks, it can use that understanding to more quickly learn to score goals. This might just be my perception though.

[@vibovitold]

the next logical step would be (and it's probably already done to some extent, in one way or another) to split the AI into a "teacher" (supervisory) and a "pupil" (learning) AI, whereby the former one would be in charge of figuring out and setting the incremental goals for the latter to accomplish

We already have the technology to gather this data from cameras (tesla). Then we would train the AI agents. And if they can control these soccer players that have at least 20 different joint controls that need such fine tuning, we should be able to train an agent to drive a car, even have races, do tricks, or just drive from point A to B without crashing.

"What happens if they drop an Ai in with a team mate that already knows how to play?? Do they learn faster?

As far as I I understood what I saw, they weren't really passing. It was more like a combination of 0) Run towards the ball 1) Shoot as close to the goal as possible while avoiding the enemy (including bouncing off of the wall) 2) If teammate has the ball then position towards the middle and the goal (essentially where teammate will shoot), which is indeed impressive It may not sound like there is a difference, but there is, because passing to a teammate so he can shoot at the empty net is not the same as shooting the ball next to the enemy, missing the goal, and hope teammate gets there (who gets there, because he expects the missed shot)

[@wihatmi5510]

To make it more realistic the ai should no only know which movements are possible but also in which position how much force the body can create and also how fast the whole body or certain parts of it get tired and take all this into account. Also they should have a field of vision with moving eyes that can only focus on a certain point directly and just aprroximate the rest and not know what the others thinks but predicting it from their action. After that it might look exactly like real soccer. Maybe it's possible to use it in a video game. The player just selects who they want to control and points in the direction and shoots and everything else is done by the AI.

Pure gold, they play like half of my classmates on PE :D

Great video and very interesting. AI learning is so crazy. I feel that in the future this will become the base for programmers' jobs, where they will only come in to tweak and finalize code initially generated by AI. Feedback I have for your video, is that the insane fluctuation of your narration made it slightly difficult to watch..

Watching all this physics simulations and last Boston Dynamics video about Atlas and all the struggles they get, i'm interested when BD will use machine learning instead of direct behavioral coding?

[@NigraXXL]

I'm pretty sure they already do. They have a simulation they use to train stuff, then make adjustments if the output doesn't work in real life

I was wondering if fatigue could be a metric, calculating how much energy it takes to move around in the way that they do, and what might be optimized if muscle contractions based on relative joint positions, movement speed, etc. were accounted for along with a fatigue rate the longer they played. They seem to be going all out all the time, which is not something humans can do. This might be why they still move in such a flailing manner, not accounting for the energy cost.

The way they move and play looks so funny and too much training will probably iron out that character.
