摘要:

在物理人机交互中,机器人和人类在同一工作空间中的共存需要保证稳定的交互,试图最大限度地减少操作员的努力。为此,导纳控制被广泛使用,其参数的适当选择是至关重要的,因为它们影响机器人的稳定性和与用户交互的能力。在本文中,我们提出了一种策略,用于检测偏差的标称行为的导纳控制的机器人和适应的控制器的参数,同时保证无源性。所提出的方法在KUKA LWR 4+上进行了验证。

英文摘要:

In physical human-robot interaction, the coexistence of robots and humans in the same workspace requires the guarantee of a stable interaction, trying to minimize the effort for the operator. To this aim, the admittance control is widely used and the appropriate selection of the its parameters is crucial, since they affect both the stability and the ability of the robot to interact with the user. In this paper, we present a strategy for detecting deviations from the nominal behavior of an admittance-controlled robot and for adapting the parameters of the controller while guaranteeing the passivity. The proposed methodology is validated on a KUKA LWR 4+.
