机器人不再让机器人在现实里死磕，而是让机器人在脑子里给自己造了一个‘梦境实验室’。它在现实里只需要少量的尝试，就能在脑子里推演几万次。

世界模型是机器人的一种“梦境实验室”，它允许机器人在大脑中模拟现实环境。通过将摄像头画面和关节感应数据压缩成紧凑的“离散代码”，机器人可以建立一个循环状态空间模型（RSSM）。这个模型能够预测不同动作产生的后果，使机器人无需在现实中真实操作，就能在脑海里推演成千上万次，从而极大地降低了现实世界中的试错成本。
这得益于其独特的“解耦”设计和 Actor-Critic 机制。机器人拥有两个并行的线程：一个“执行者”在现实中进行少量尝试并收集数据，另一个“学习者”则利用这些数据不断修补和优化“梦境”。由于“演员”网络是在 GPU 驱动的虚拟轨迹中进行高强度的排练和进化，它能在极短的时间内掌握翻身、站立和行走等复杂动作。
该框架具有极强的自适应和在线学习能力。在机械臂实验中，即使遇到日出导致的光影剧烈变化，机器人虽然初期性能会下降，但它能通过不断更新自己的世界模型，在约 5 小时内适应新环境，性能甚至能超过之前的水平。这种持续进化的能力让机器人能够应对现实世界中不可预见的干扰。
它标志着机器人学习范式的转变，从依赖死板的预写代码或高误差的电脑模拟器，转向让机器人在现实中“边玩边学”。DayDreamer 证明了同一个算法框架可以适配四足机器人、机械臂和球形机器人等多种形态。随着该基础设施的开源，机器人学习的门槛大大降低，开发者可以更专注于提供学习框架，让机器人通过自身的“想象力”去理解和适应复杂的现实世界。
