基于传感器的反应式与混合式方法在处理抓取与操作中的不完全知识方面展现出良好前景。然而,反应式方法通常紧密耦合于特定机器人形态,导致知识难以迁移。本文提出一种反应式操作行为的建模与执行范式,使知识可在不同形态间迁移的同时保留各平台的反应能力。该方法通过状态机协调抽象操作原语,建立与具体平台无关的抽象层。这些抽象原语构成一组原子级、平台无关的动作词汇,可通过状态机组合描述复杂操作。为获取具体平台的模型,抽象状态机可自动转换为对应平台的特异性模型,从而充分发挥各平台性能。通过开发用于物体传送的一系列具体化原语(包括复杂的反应式抓取原语),验证了该范式的有效性。实验在清空装有多个未知物体的盒子任务中评估其鲁棒性,结果表明系统在不同场景下均能稳定工作;通过在两种不同平台上使用同一抽象描述完成操作任务,验证了其形态独立性。
原文摘要 · Abstract (English)
Sensor-based reactive and hybrid approaches have proven a promising line of study to address imperfect knowledge in grasping and manipulation. However the reactive approaches are usually tightly coupled to a particular embodiment making transfer of knowledge difficult. This paper proposes a paradigm for modeling and execution of reactive manipulation actions, which makes knowledge transfer to different embodiments possible while retaining the reactive capabilities of the embodiments. The proposed approach extends the idea of control primitives coordinated by a state machine by introducing an embodiment independent layer of abstraction. Abstract manipulation primitives constitute a vocabulary of atomic, embodiment independent actions, which can be coordinated using state machines to describe complex actions. To obtain embodiment specific models, the abstract state machines are automatically translated to embodiment specific models, such that full capabilities of each platform can be utilized. The strength of the manipulation primitives paradigm is demonstrated by developing a set of corresponding embodiment specific primitives for object transport, including a complex reactive grasping primitive. The robustness of the approach is experimentally studied in emptying of a box filled with several unknown objects. The embodiment independence is studied by performing a manipulation task on two different platforms using the same abstract description.
