摘要:

在过去的二十年里,科学界对理解和塑造人类与机器人之间的交互机制表现出极大的兴趣。交互意味着两个二元代理之间的通信,如果交互类型是物理的,则通信由交互期间交换的力的集合表示。在这种情况下,量化这些力量的作用变得至关重要的相互作用机制的理解。在目前的科学阶段,经典机器人是为人类而建造的,但科学需求正在朝着机器人必须与人类合作的方向发展。这将通过向机器人提供它们正在与之交互的代理的足够多的信息(即,人的运动学和动力学模型)。在人类需要机器人帮助的现代,显然是相反的趋势,本文试图回答以下问题:机器人需要人类吗?机器人应该认识他们的人类伙伴吗?这里提供了一个试探性的答案,在一个实时的情况下,同时人体全身运动跟踪和动态估计的新框架的形式。该框架包括一组安装在身体上的传感器和能够估计人体中不可直接测量的物理量的概率算法(即,扭矩和内力)。这篇论文主要集中在检索人体动力学估计的最重要的作用,但直截了当地说,它留下了大门打开下一个发展步骤:通过人体动力学反馈的机器人控制器。这一步将使机器人能够通过生成增强的(有意的)交互来观察和理解人类伙伴。

英文摘要:

In the last two decades the scientific community has shown a great interest in understanding and shaping the interaction mechanisms between humans and robots. The interaction implies communication between two dyadic agents and, if the type of interaction is physical, the communication is represented by the set of forces exchanged during the interaction. Within this context, the role of quantifying these forces becomes of pivotal importance for understanding the interaction mechanisms. At the current scientific stage, classical robots are built to act for humans, but the scientific demand is going towards the direction of robots that will have to collaborate with humans. This will be possible by providing the robots with sufficient pieces of information of the agent they are interacting with (i.e., kinematic and dynamic model of the human). In a modern age where humans need the help of robots, apparently in an opposite trend, this thesis attempts to answer the following questions: Do robots need humans? Should robots know their human partners? A tentative answer is provided here in the form of a novel framework for the simultaneous human whole-body motion tracking and dynamics estimation, in a real-time scenario. The framework encompasses a set of body-mounted sensors and a probabilistic algorithm able of estimating physical quantities that in humans are not directly measurable (i.e., torques and internal forces). This thesis is mainly focussed on the paramount role in retrieving the human dynamics estimation but straightforwardly it leaves the door open to the next development step: passing the human dynamics feedback to the robot controllers. This step will enable the robot with the capability to observe and understand the human partner by generating an enhanced (intentional) interaction.
