论文摘要
控制器的层次结构协调通常使用符号状态表示形式,这些表示完全抽象其潜在的低级控制器,将其视为符号动作抽象的“黑匣子”。本文提出了一个框架来实现强大的行为,我们称基于可行性的控制链协调(FC $^3 $)。我们的控制器揭示了他们操作的几何特征和约束。基于此,FC $^3 $可以理解控制器的可行性及其序列可行性。对于给定的任务,FC $^3 $首先使用符号动作树自动构建一个潜在控制器链的库,然后将其用于协调链中的控制器,评估任务可行性,并在必要时在控制器链之间进行切换。在几个现实世界中,我们通过其自身的行动和对不同干扰的逐步响应来证明FC $^3 $的鲁棒性和对任务可行性的认识。
Hierarchical coordination of controllers often uses symbolic state representations that fully abstract their underlying low-level controllers, treating them as "black boxes" to the symbolic action abstraction. This paper proposes a framework to realize robust behavior, which we call Feasibility-based Control Chain Coordination (FC$^3$). Our controllers expose the geometric features and constraints they operate on. Based on this, FC$^3$ can reason over the controllers' feasibility and their sequence feasibility. For a given task, FC$^3$ first automatically constructs a library of potential controller chains using a symbolic action tree, which is then used to coordinate controllers in a chain, evaluate task feasibility, as well as switching between controller chains if necessary. In several real-world experiments we demonstrate FC$^3$'s robustness and awareness of the task's feasibility through its own actions and gradual responses to different interferences.
