Team teleoperation, which is commonly seen in dangerous and inaccessible environments, is challenging by the complexity and dynamics of the environment, especially when there is time delay. This study was focused on Two-Operator-Two-Robot teleoperation and discussed the influence of time delay on team performance. In this study, we collected operational performance data, eye movement data and subjective rating to compare the performance of an object moving task with 0 s and 3.73 s time delay. Preliminary results of the experiment indicate that the increase of time delay significantly increase completion time and decrease fraction of time moving (MRATIO). In addition, time delay significantly increase the variance of the number of collisions and joint limit reach, which suggest that the inter-individual difference become greater under time delay.
