Performing language-conditioned robotic manipulation tasks in unstructured environments is highly demanded for general intelligent robots. Conventional robotic manipulation methods usually learn semantic representation of the observation for action prediction, which ignores the scene-level spatiotemporal dynamics for human goal completion. In this paper, we propose a dynamic Gaussian Splatting method named ManiGaussian for multi-task robotic manipulation, which mines scene dynamics via future scene reconstruction. Specifically, we first formulate the dynamic Gaussian Splatting framework that infers the semantics propagation in the Gaussian embedding space, where the semantic representation is leveraged to predict the optimal robot action. Then, we build a Gaussian world model to parameterize the distribution in our dynamic Gaussian Splatting framework, which provides informative supervision in the interactive environment via future scene reconstruction. We evaluate our ManiGaussian on 10 RLBench tasks with 166 variations, and the results demonstrate our framework can outperform the state-of-the-art methods by 13.1\% in average success rate.

在这篇论文中，我们提出了一种名为ManiGaussian的动态高斯斑点方法，用于多任务机器人操作，该方法通过未来场景重建来挖掘场景动态性。我们首先制定了动态高斯斑点框架，推断高斯嵌入空间中的语义传播，利用语义表示来预测最佳机器人动作。然后，我们建立了一个高斯世界模型来参数化我们的动态高斯斑点框架中的分布，通过未来场景重建在交互环境中提供信息化监督。我们在10个RLBench任务的166个变体上评估了ManiGaussian，并且结果表明我们的框架在平均成功率上比现有最先进方法提高了13.1%。
