在劳动密集型制造业劳动力老龄化的社会背景下，我们讨论了针对老年工人（主要是40多岁和50多岁）的援助制度，这些工人虽然体能下降，但在八小时轮班中以恒定速度高质量执行迭代任务的体能有所下降，但仍具有出色的技能。本文提出的“技能辅助”是一种新型的辅助系统，通过改变其机械阻抗，让在终身雇佣制下工作的工人获得再次能够完成年轻时能够完成的技能任务的成就感。本文讨论了基于可变阻抗控制的Skill-Assist控制算法。首先，解释响应任务条件变化而改变技能辅助阻抗的标准。其次，讨论了通过实验确定为理想的阻抗模式。这些模式是在基于改变阻抗的标准操纵技能辅助和精确定位时产生良好的主观操作感所需的模式。最后给出了Skill-Assist的控制算法。该算法是根据一项选定的迭代定位任务的主观操作感觉、身体压力和生产力来估计的。
In the social context of an aging workforce in the labor intensive manufacturing sector, we discuss an assistance system for older workers (mainly in their 40's and 50's) who have excellent skills though their physical ability to perform iterative tasks at a constant speed with high quality over one eight hour shift has declined. "Skill-Assist" which is proposed in this paper is a new type of assisting system which varies its mechanical impedance to give workers who have been working under the lifetime employment system a sense of achievement in being again able to accomplish the skilled tasks they were capable of when younger. This paper discusses the control algorithm of Skill-Assist based on variable impedance control. First, a criterion for varying the impedance of Skill-Assist in response to task condition variations is explained. Second, impedance patterns experimentally determined to be desirable are discussed. These patterns are those required to produce a good subjective operational feel when maneuvering Skill-Assist and precise positioning based on the criterion for varying the impedance. Finally, the control algorithm of Skill-Assist is presented. This algorithm is estimated based on the subjective operational feel, physical stress, and productivity of one selected iterative positioning task.
