Abstract:
RoboLeader, an intelligent agent, was developed to assist human operators in controlling a team of unmanned vehicles through route planning tasks. Though there were no significant differences between the RoboLeader and baseline conditions in target detection, the RoboLeader group reduced their mission completion times by approximately 13% compared to the baseline group. Operators' target detection performance in the four- and eight-vehicle conditions were analyzed, with results showing significantly fewer targets identified in the eight-vehicle condition compared to the four-vehicle condition. Participants with higher spatial ability detected more targets than those with lower spatial ability. Participants experienced significantly higher workload in the eight-vehicle condition compared to the four-vehicle condition. Participants with better attentional control reported lower workload than those with poorer attentional control, and females reported significantly higher workload than males.
