Abstract: We simulated a Mounted Combat System (MCS) environment and conducted an experiment to examine the workload and performance of the combined position of gunner and robotic operator. Results showed that gunner?s target detection performance degraded significantly when s/he had to concurrently monitor, manage, or teleoperate an unmanned ground vehicle compared to the baseline condition (gunnery task only). For the robotic tasks, participants detected significantly fewer targets when their robotic asset was semi-autonomous instead of teleoperated. The effects of individual difference factors such as spatial ability and perceived attentional control on the performance measures were also examined.
