🛠️ Technical Deep Dive
- The Brain-Cerebellum architecture employs a dual-stream transformer design where the Brain stream processes long-horizon semantic planning and the Cerebellum stream processes short-horizon reactive control.
- The model utilizes a shared multimodal self-attention mechanism that processes visual tokens, text instructions, and proprioceptive state tokens in a unified latent space.
- Action generation is handled via a discrete action-token head, which maps latent representations to specific joint velocity or position commands.
- The four-stage training strategy includes: 1) Large-scale VLM pre-training, 2) Embodied video sequence prediction, 3) Action-conditioned behavioral cloning, and 4) Reinforcement learning fine-tuning for safety constraints.
