ABSTRACT

Objective: This study is to construct a model composed of multiple indices to measure astronaut teleoperation performance.

Background: Teleoperation is a key operation during spaceflight. Comprehensive scientific evaluation techniques for teleoperation performance are important for astronaut selection and training.

Method: Four categories of indices, i.e., completion performance, safety performance, subjective cognitive performance and physiological parameters, were adopted in this model. The fuzzy analytic hierarchy process (AHP) was used to compute the weight coefficients of the indices to construct the linear performance model. Sixty-four male subjects were recruited to complete three teleoperation tasks, including point aiming, line alignment, and obstacle avoidance, in simulated environments. Their performance was rated by the researchers after the tasks.

Results: The safety performance index had the highest weight coefficient (0.5274) of the first level indices, and the weight coefficient of the collisions index (0.8227) was the highest of the second level indices for safety performance. The linear performance model was constructed to calculate comprehensive performance values.

Conclusion: Safety considerations are the most important factors for astronauts to consider in teleoperation. The collision of the robotic arm is the most vital safety index. The comprehensive value derived from the model was significantly related to overall performance. The validity of our model was verified, and it is anticipated that the model will be used to evaluate the performance of remote robotic arm operations.

摘要

目的：本研究旨在建立一个由多个指标组成的模型，以测量宇航员的遥操作性能。

背景：遥操作是太空飞行中的关键操作。全面的远程操作性能科学评估技术对宇航员的选择和培训很重要。

方法：该模型采用四类指标，即完成表现，安全表现，主观认知表现和生理参数。采用模糊层次分析法计算指标的权重系数，建立线性绩效模型。招募了64名男性受试者，以在模拟环境中完成三项遥操作任务，包括点瞄准，线对齐和避障。任务完成后，研究人员对他们的表现进行了评分。

结果：安全绩效指标的权重系数在第一级指标中最高（0.5274），而碰撞指标的权重系数（0.8227）在第二级指标中最高。构建线性性能模型以计算综合性能值。

结论：安全考虑是宇航员在遥控操作中要考虑的最重要因素。机械臂的碰撞是最重要的安全指标。该模型得出的综合价值与整体绩效显着相关。我们的模型的有效性得到了验证，并且可以预期该模型将用于评估远程机械臂操作的性能。
