π0.7發布，VLA押出機器人的GPT-3時刻

🔑 增強重點摘要

• •The π0.7 model utilizes a Vision-Language-Action (VLA) architecture trained on a massive, diverse dataset of real-world robotic manipulation tasks, enabling cross-embodiment generalization.
• •Unlike previous iterations, π0.7 incorporates a novel 'controllable framework' that allows human operators to adjust safety constraints and task priorities in real-time without retraining the base model.
• •The release marks a shift from specialized, task-specific robot training to a foundation model approach, significantly reducing the data requirements for deploying robots in novel environments.

🛠️ 技術深入

• •Architecture: Employs a transformer-based VLA backbone that tokenizes visual inputs, natural language instructions, and robot proprioceptive state data.
• •Training Data: Leveraged a hybrid dataset combining large-scale simulation data with high-fidelity real-world robotic interaction data to bridge the sim-to-real gap.
• •Inference: Utilizes a latent action space representation, allowing the model to output continuous control signals for robotic actuators at high frequencies.
• •Controllability Mechanism: Implements a conditioning layer that allows external policy guidance or 'safety masks' to be applied during inference to steer model behavior.
