AI总结:

本文提出MMD算法,将学习到的扩散模型与经典搜索技术结合,仅用单机器人数据即可为数十个机器人规划无碰撞轨迹,并支持组合多个扩散模型以扩展到大环境。

摘要:

扩散模型最近已成功应用于广泛的机器人应用,用于从数据中学习复杂的多模态行为。然而,由于学习多机器人扩散模型的高样本复杂度,先前的工作大多局限于单机器人和小规模环境。在本文中,我们提出了一种仅使用单机器人数据生成无碰撞多机器人轨迹的方法,使轨迹符合底层数据分布。我们的算法,多机器人多模型规划扩散(MMD),通过将学习到的扩散模型与经典的基于搜索的技术相结合来实现这一点——在碰撞约束下生成数据驱动的运动。进一步扩展规模,我们展示了如何组合多个扩散模型,在单个扩散模型难以良好泛化的大环境中进行规划。我们在受物流环境启发的多种模拟场景中,证明了我们的方法在为数十个机器人进行规划时的有效性。视频演示和代码见:https://multi-robot-diffusion.github.io/。

英文摘要:

Diffusion models have recently been successfully applied to a wide range of robotics applications for learning complex multi-modal behaviors from data. However, prior works have mostly been confined to single-robot and small-scale environments due to the high sample complexity of learning multi-robot diffusion models. In this paper, we propose a method for generating collision-free multi-robot trajectories that conform to underlying data distributions while using only single-robot data. Our algorithm, Multi-robot Multi-model planning Diffusion (MMD), does so by combining learned diffusion models with classical search-based techniques -- generating data-driven motions under collision constraints. Scaling further, we show how to compose multiple diffusion models to plan in large environments where a single diffusion model fails to generalize well. We demonstrate the effectiveness of our approach in planning for dozens of robots in a variety of simulated scenarios motivated by logistics environments.
