  • 将机器人系统建模为范畴论中的抽象电路,支持软硬件协同动态组合。
  • 在搜救场景中实测,机器人能识别失效并自动合成新配置恢复运行。
  • 适合长期服役的智能机器人系统研发,尤其需持续适应环境的任务。

传统机器人系统采用设计后部署的静态架构,运行时无法应对自身、任务或环境的意外变化。本文提出一种组合式框架,将机器人系统形式化为严格对称单对象范畴内的抽象电路,通过SMT求解器在设计与运行阶段同步合成硬件、软件与行为模块。利用范畴函子将系统投影至不同生命周期视角,同时求解参数与组件规格。该持久模型支持长期系统所需查询:如候选构型的帕累托前沿映射、失效原因诊断、最小恢复方案发现及有限修改下的重构。在部署机器人上对比了最优数值、流式与SMT规划器,并在搜救场景中端到端验证:机器人能自主识别不适配状态并合成全新整体构型以恢复运行。代码与工具已开源。

原文摘要 · Abstract (English)

Robotic systems are traditionally designed and deployed in static configurations, with assumptions made at design-time becoming immutable constraints during runtime. This design-then-deploy paradigm produces performant systems under narrow operating conditions, but renders robots brittle when qualities of themselves, their tasks, or their environments unexpectedly change. We address this challenge with a compositional framework that formalizes robotic systems as abstract circuits within a strict symmetric monoidal category, in which design and runtime composition of hardware, software, and behavior are synthesized simultaneously via an SMT-based solver, with monoidal functors projecting the system into lifecycle-specific views and free symbolic variables simultaneously solving for parameters and entire component specifications within larger compositions. This persistent model also supports queries a long-lived system needs beyond plan existence across its entire lifecycle, including mapping Pareto fronts over candidate compositions, diagnosing why a composition has become infeasible, finding its minimal restoration, and reconfiguring with limited change to the deployed system. We evaluate against official implementations of optimal numeric, stream-based, and SMT-based planners all measured onboard a deployed robot and demonstrate the approach end-to-end in a search-and-rescue scenario in which the robot recognizes when it has become unfit and synthesizes and assumes new holistic configurations to restore operation. We release our solver and supporting software open-source.
