Humanoid soccer goes outdoors with no instrumentation
Pulkit Agrawal says the policy dribbles, passes, turns and scores after simulation training alone.
Humanoid soccer just left the lab. Pulkit Agrawal posted that his group ran humanoid soccer on real fields, around people, with no instrumentation and no controlled environment. The robots dribble, pass, turn and score goals.
Trained in simulation. Deployed in reality. No post-training. Just pre-training.
Taking humanoid soccer out of the lab: no instrumentation, no controlled environment. Real fields, around people.
The claim that matters is how the policy got there. Agrawal says it was trained in simulation and deployed in reality with no post-training, only pre-training. That means no extra tuning on the real robot after the sim run, which is the step most sim-to-real (trained in simulation, run on the real robot) pipelines lean on to close the gap between a physics engine and a grass field.
Why no instrumentation is the interesting part
Most humanoid soccer you have seen happens on a marked indoor pitch with motion capture cameras ringing the space, feeding the robot exact positions of itself and the ball. Take that away and the robot has to work from what it carries. Agrawal's description says there was none of that, and no controlled environment either. Real fields, with people around.
The work is led by Avi, Khai and @nolan_fey, along with @martinpeticco, @JohnMarangola and Venki.
What is not in the post
One post is all there is so far. There is no paper, no video breakdown of the failure cases, no success rate on any of the four behaviors listed, and no detail on the hardware or what sensing the robots use to find the ball. Nobody outside the group has run this yet.
So treat the specifics as the team's account. Sim-to-real with zero post-training is the kind of claim that lives or dies on how often it works, not on whether it can work once. A robot that scores in a clip and a robot that plays a match are different results, and the post does not separate them. Worth watching for the full release.
