In this study, we simulated a generic mounted crew station environment and conducted an experiment to examine the workload and performance of the operator of a ground robot. Participants were randomly assigned to four tasking conditions: robotics tasks only, robotics plus an auditory task, robotics plus a visual monitoring task, or all three tasks simultaneously. Participants completed four mission scenarios. In two of these scenarios, their robot was semiautonomous. In the other two scenarios, they had to teleoperate the robot. An Aided Target Recognition (AiTR) system was available to help them with their target detection tasks in only two of the four scenarios. Results showed that operators' situational awareness and perceived workload were significantly worse when they teleoperated the robot. Individual differences factors such as the operator's spatial ability and attentional control were also investigated. Implications for military personnel selection were discussed.
