摘要:

在机器人教学中,许多工作要么只注重教学任务知识,如几何约束,或运动知识,如完成任务的运动。然而,为了有效地教一个复杂的任务序列的机器人,重要的是要利用任务和运动知识。任务知识提供了序列中每个单独任务的目标,并减少了所需的人类演示的数量,而运动知识包含任务到任务的约束,否则需要专家知识来建模的问题。在本文中,我们提出了一个机构的角色分工的方法,结合了这两种类型的知识,使用一个单一的人类示范。该方法的灵感来自于人体运动的事实,并使用身体结构的类比分解成不同的角色机器人的身体配置:身体部位是主要的模仿人体运动和身体部位的替代调整模仿相对于任务知识。我们的研究结果表明,我们的方法可扩展到不同数量的手臂链接的机器人,引导机器人的配置,以实现即将到来的任务,并可能有利于教学范围的任务序列。

英文摘要:

Many works in robot teaching either focus only on teaching task knowledge, such as geometric constraints, or motion knowledge, such as the motion for accomplishing a task. However, to effectively teach a complex task sequence to a robot, it is important to take advantage of both task and motion knowledge. The task knowledge provides the goals of each individual task within the sequence and reduces the number of required human demonstrations, whereas the motion knowledge contain the task-to-task constraints that would otherwise require expert knowledge to model the problem. In this paper, we propose a body role division approach that combines both types of knowledge using a single human demonstration. The method is inspired by facts on human body motion and uses a body structural analogy to decompose a robot's body configuration into different roles: body parts that are dominant for imitating the human motion and body parts that are substitutional for adjusting the imitation with respect to the task knowledge. Our results show that our method scales to robots of different number of arm links, guides a robot's configuration to one that achieves an upcoming task, and is potentially beneficial for teaching a range of task sequences.
