 | A military multitasking environment was simulated to examine the performance of robotics operators whose task was to manage a team of four ground robots with the assistance of RoboLeader, an intelligent agent that could coordinate the robots by changing their plans based on developments in the mission environment. The reliability of RoboLeader s recommendations was manipulated to be either false-alarm prone (FAP) or miss prone (MP), with a reliability level ... |

| We developed an intelligent agent, RoboLeader, that could assist human operators in controlling a team of robots. More specifically, RoboLeader was able to help the operators with their route planning tasks. Although there were no significant differences between the RoboLeader and Baseline conditions for target detection performance, participants in the RoboLeader group reduced their mission completion times by 13% compared to Baseline. We also compared the operators' target detection performance ... |

| The purpose of this report is to review research pertaining to the limitations and advantages of supervisory control for unmanned vehicle (UV) systems. We identify and discuss results showing technologies that mitigate observed problems, such as specialized interfaces and adaptive systems. In the report, we first present an overview of definitions and important terms of supervisory control and human-agent teaming. We then discuss human performance issues in supervisory control of ... |

| 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 ... |

|
| 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 ... |
