概括
为了减少在人机协作 (HRC) 中工人的压力,机器人应该在工人的视野内接近,缓慢移动,并使用可预测的路径. 了解这些机器人因素对于设计压力较小的协作任务至关重要.
科学领域:
- 人与机器人的交互
- 职业安全和人体工程学
- 机器人和自动化 机器人和自动化
背景情况:
- 人机协作 (HRC) 在工业环境中越来越多地被采用.
- 识别机器人诱导的压力因素对于设计工人友好的协作任务至关重要.
- 尽量减少工人的心理压力可以提高HRC的安全性和生产力.
研究的目的:
- 调查机器人终端效应器方法方向,速度和轨迹如何影响工人在交付任务期间的心理压力.
- 量化特定机器人运动参数对生理和主观压力指标的影响.
- 为设计压力较小的HRC场景提供数据驱动的建议.
主要方法:
- 用主观自我报告和客观措施,如皮反应 (GSR) 和电肌图 (EMG) 来评估心理压力.
- 该研究分析了不同机器人接近方向,运动速度和终端效应器轨迹的影响.
- 进行了统计分析,以确定每个因素的意义及其对压力水平的相互作用.
主要成果:
- 机器人运动速度和接近方向显著影响了主观压力评级,EMG和GSR.
- 高速和侧向接近与增加的恐惧,减少舒适度和更高的压力指标相关.
- 运动轨迹影响了GSR,突然停止会比受限制的路径引起更明显的反应.
结论:
- 在HRC期间工人的心理压力是最小的,当机器人的终端效应器接近工人的视野.
- 较慢的机器人运动速度和受限制的轨迹进一步减少了工人的心理压力.
- 这些发现为设计更安全,更舒适的HRC任务提供了实际指南.

Psychological Responses to Stress
54
Psychological responses to stress encompass the various cognitive and emotional reactions individuals experience when faced with challenging or threatening situations, such as a job loss. Prolonged exposure to stressors can disturb emotional balance, increasing negative emotions (e.g., anxiety and sadness) and diminishing positive emotions (e.g., joy and satisfaction). These persistent emotional shifts are associated with an increased risk of both physical illness and mental health issues, such...

Types of Stressors
198
A stressor is any event, condition, or stimulus that triggers stress and causes a physical or psychological response in the body. Stressors can be categorized into three main types: catastrophes; significant life changes; and daily hassles, including social stress. Each can be detrimental to physical and mental well-being.
Catastrophes
Catastrophes refer to large-scale, unpredictable events that create overwhelming stress and a sense of threat. Examples include natural disasters like...

Effective communication among healthcare professionals during hand-off reporting is essential to delivering safe and continuous patient care. Common professional interactions include reports to healthcare team members, hand-off, and transfer reports. Nurses routinely report information to other healthcare team members and also urgently contact healthcare providers to report changes in patient status.

Stress and Mental Health
157
Chronic stress profoundly affects mental health, significantly influencing mood, behavior, and overall quality of life. Research closely links chronic stress with mental health conditions such as depression, anxiety, and substance use disorders. Ongoing exposure to stress can lead to physiological and psychological changes, initiating a cycle of emotional distress and maladaptive coping mechanisms.
