📝 摘要(中文)
模块化机器人研究已开发出能够在线改变机器人形态的方法,然而,本文提出的目标是构建能够在多个领域(如运动学、感知、计算和高层协调行为)中改变基本能力的机器人。我们称这种跨域重配置能力为集成跨度,并引入集成惯性作为对重配置的抵抗度量。当前的模块化机器人在结构域的集成惯性较低,但在其他领域仍然较高。我们提出的重组机器人系统旨在最大化集成跨度并最小化集成惯性,涵盖硬件、软件、计算和行为的异构模块,进而推动这一领域的未来发展。
🔬 方法详解
问题定义:本文旨在解决现有模块化机器人在多领域能力适应性不足的问题。当前方法在结构域的重配置能力较强,但在其他领域(如感知和行为)仍然存在较高的集成惯性,限制了机器人的整体适应性。
核心思路:提出重组机器人概念,强调跨域重配置能力,旨在通过整合硬件、软件、计算和行为模块,提升机器人的适应性和灵活性。设计思路是通过降低集成惯性,来实现更高的集成跨度。
技术框架:整体架构包括多个模块,首先是能力评估模块,评估机器人在不同领域的能力;其次是重配置决策模块,根据评估结果决定重配置方案;最后是执行模块,实施重配置并调整机器人的运动规划和控制策略。
关键创新:最重要的创新在于引入了集成跨度和集成惯性两个概念,强调了跨域重配置的必要性。这与现有方法的单一领域重配置形成了鲜明对比,提供了更全面的适应性解决方案。
关键设计:在设计中,采用了模块化接口,使得各个组件能够独立重配置。损失函数设计上考虑了多领域能力的平衡,确保在重配置过程中不会损失某一领域的性能。

📄 摘要(原文)
Research in modular robotics has produced capable approaches allowing a robot's morphology to change online, with recent efforts also developing approaches to decide which morphology to assume and automatically propagate that decision into the robot's motion planning and control. These approaches are powerful and increase adaptability in the field. However, an alternative objective is not to build robots whose structures can change, but robots whose fundamental capabilities can change, where capability is a joint function across several domains, including kino-dynamics, perception, compute, and high-level coordinating behaviors. A robot designed to be reconfigured across these domains has a greater capacity to alter its capability than one that can be reconfigured in a single domain. We refer to this cross-domain reconfigurability as integration span, and recognize a complementary measure of the resistance to reconfiguration, which we refer to as integration inertia. Current modular robots have reduced integration inertia in the structural domain while it remains high in the other domains that contribute to integration span. We assert that the systems that can provide the most utility through reconfiguration in practice are those maximizing span and minimizing inertia and call this general problem recompositional robotics: adaptation over a heterogeneous set of modules including hardware, software, compute, and behavior that abstracts each component by the interfaces it requires and provides such that they can be reasoned over holistically. We define the problem, ground it in two deployed systems and active research efforts, and pose open questions about the future of recompositional robotics.
