论文摘要
在混合工业环境中，工人对安全性的舒适性和积极的看法是成功接受和使用协作机器人的重要要求。本文提出了一个新型的人类机器人互动框架，其中根据操作员的认知工作量和压力在线对机器人行为进行了调整。该方法利用了在关节空间中生成B-Spline轨迹的生成，并将多目标优化问题的公式用于在线调整机器人轨迹的总执行时间和平滑度。前者确保了工作场所的人力效率和生产力，而后者则有助于保护用户的舒适性和认知人体工程学。在典型的工业任务中评估了拟议框架的性能。结果表明，其能力可以提高人类二元组的生产率，同时减轻工人引起的认知工作量。
In hybrid industrial environments, workers' comfort and positive perception of safety are essential requirements for successful acceptance and usage of collaborative robots. This paper proposes a novel human-robot interaction framework in which the robot behaviour is adapted online according to the operator's cognitive workload and stress. The method exploits the generation of B-spline trajectories in the joint space and formulation of a multi-objective optimisation problem to online adjust the total execution time and smoothness of the robot trajectories. The former ensures human efficiency and productivity of the workplace, while the latter contributes to safeguarding the user's comfort and cognitive ergonomics. The performance of the proposed framework was evaluated in a typical industrial task. Results demonstrated its capability to enhance the productivity of the human-robot dyad while mitigating the cognitive workload induced in the worker.
