This tutorial presents an architecture for autonomous robots to generate behavior in joint action tasks. To efficiently interact with another agent in solving a mutual task, a robot should be endowed with cognitive skills such as memory, decision making, action understanding and prediction. The proposed architecture is strongly inspired by our current understanding of the processing principles and the neuronal circuitry underlying these functionalities in the primate brain. As a mathematical framework, we use a coupled system of dynamic neural fields, each representing the basic functionality of neuronal populations in different brain areas. It implements goal-directed behavior in joint action as a continuous process that builds on the interpretation of observed movements in terms of the partner's action goal. We validate the architecture in two experimental paradigms: (1) a joint search task; (2) a reproduction of an observed or inferred end state of a grasping-placing sequence. We also review some of the mathematical results about dynamic neural fields that are important for the implementation work.
本教程介绍了一种用于自主机器人在联合行动任务中生成行为的架构。为了在解决共同任务时与另一个智能体高效交互,机器人应具备诸如记忆、决策、动作理解和预测等认知技能。所提出的架构深受我们目前对灵长类大脑中这些功能背后的处理原则和神经回路的理解的启发。作为一个数学框架,我们使用动态神经场的耦合系统,每个系统代表不同脑区神经元群体的基本功能。它将联合行动中的目标导向行为实现为一个连续过程,该过程基于根据伙伴的行动目标对观察到的动作进行的解释。我们在两个实验范式中验证了该架构:(1)联合搜索任务;(2)抓取-放置序列的观察到的或推断出的最终状态的再现。我们还回顾了一些关于动态神经场的数学结果,这些结果对实现工作很重要。
