Post-Training Isaac GR00T N1.5 for LeRobot SO-101 Arm

honestly? they're just trying to shoehorn vision-language models onto robotics. the real cost here isn't the training itself, it's making sure this post-training adaptation actually works reliably on real-world hardware. n1.5 is fine, but if the deployment pipeline sucks, it's just expensive code. we're still waiting for true generalization before we start throwing millions at fine-tuning specific arms. it's a nice tool, but don't expect magic yet.

we need better benchmarks than just the arm's reach. if this doesn't translate efficiently to physical interaction, it's just a fancy benchmark.
