Camera guided teleoperation has long been the preferred mode for controlling remote robots, with other modes such as asynchronous control only used when unavoidable. In this experiment we evaluate the usefulness of asynchronous operation for a multirobot search task. Because controlling multiple robots places additional demands on the operator, removing the forced pace for reviewing camera video might reduce workload and improve performance. In the reported experiment participants operated four robot teams performing a simulated urban search and rescue (USAR) task using either conventional streaming video plus a map interface or an experimental interface without streaming video but with the ability to store panoramic images on the map to be viewed at leisure. Search performance was somewhat better using the conventional interface, however, ancillary measures suggest that the asynchronous interface succeeded in reducing temporal demands for switching between robots.
