弥合机器人高层推理与执行之间的差距

Towards Bridging the Gap between High-Level Reasoning and Execution on Robots

RWTH Aachen University(亚琛工业大学)

AI总结:

本文针对机器人高层抽象推理与底层复杂执行之间的差距,提出多种方法以处理执行阶段的时序约束与噪声问题,弥合两者间的鸿沟。

摘要:

在推理动作时(例如通过任务规划或使用 Golog 进行智能体编程),机器人的动作通常在抽象层面上建模。诸如抓取物体之类的复杂动作被视为原子基元,具有确定性效果且仅依赖于当前状态的前提条件。然而,在机器人上执行此类动作时,它不再能被视为基元。相反,动作执行是一项复杂任务,涉及多个步骤以及额外的时间前提条件和时序约束。此外,动作可能带有噪声,例如产生错误的感知结果且并不总是达到预期效果。虽然这些方面在推理任务中通常被忽略,但在执行过程中必须加以处理。在本论文中,我们提出了几种弥合这一差距的方法。

英文摘要:

When reasoning about actions, e.g., by means of task planning or agent programming with Golog, the robot's actions are typically modeled on an abstract level, where complex actions such as picking up an object are treated as atomic primitives with deterministic effects and preconditions that only depend on the current state. However, when executing such an action on a robot it can no longer be seen as a primitive. Instead, action execution is a complex task involving multiple steps with additional temporal preconditions and timing constraints. Furthermore, the action may be noisy, e.g., producing erroneous sensing results and not always having the desired effects. While these aspects are typically ignored in reasoning tasks, they need to be dealt with during execution. In this thesis, we propose several approaches towards closing this gap.
