RBR continues to impress on the fundamentals. The new dev update highlights steady progress on the systems that actually make Physical AI possible. Hugging Face integration brings structured model management, the fine tuning SDK introduces imitation learning and RLHF in PyBullet, and the 3D mapping toolkit moves them closer to robots that can learn from and interact with real environments. It feels like the groundwork for a serious AI-robotics infrastructure layer rather than another hype cycle project. With this level of technical depth and steady delivery, the current valuation looks like it hasn’t caught up to the scope of what they’re building yet.(NekoZ)
