## Frequently Asked Questions

### Should I use Hugging Face LeRobot or Physical Intelligence openpi (Pi0) for real-world robot manipulation in 2026?
Choose Hugging Face LeRobot (28.3k stars, Apache-2.0) as your complete PyTorch hardware-to-dataset harness (supporting $250 SO-100/SO-101 3D-printed arms, Koch v1.1, ALOHA, and Parquet/MP4 Hugging Face Hub datasets) with built-in ACT, Diffusion Policy, and Pi0 wrappers. Choose Physical Intelligence openpi (14.3k stars, Apache-2.0) when you want direct access to the official Pi0 flow-matching and Pi0-FAST token checkpoints for 50Hz dexterous bimanual tasks like laundry folding or assembly.

### How do Genesis and NVIDIA Isaac Lab compare for GPU reinforcement learning in robotics?
Choose Genesis (`genesis-embodied-ai/Genesis`, 30.1k stars, Apache-2.0) for lightweight `pip install genesis-world` setup, differentiable MPM/FEM soft-body physics, and 43 million FPS rigid-body simulation (training a Unitree Go2 locomotion policy in 26 seconds on a single RTX 4090). Choose NVIDIA Isaac Lab (8.4k stars, BSD-3-Clause) when you need industrial OpenUSD digital twins, RTX ray-traced sensor synthesis, and native ROS 2 hardware-in-the-loop deployment.
