Performance or shared situation awareness. Results indicate that the training in (3) generated more team communication than (1), but this did not improve team Four explanation-based communication conditions were tested: (1) always explain–the robot automatically provided explanations for any off-plan behaviors, (2) explain if asked–the robot provided an explanation only when the human counterpart requests it, (3) pull prime–the same as (2) but participants also experienced implicit training to pull information from the robot, and (4) never explain–a baseline condition in which the robot acknowledged requests but would not provide an explanation. A virtual USAR team task experiment was conducted in Minecraft with a confederate acting as the remote robot. Communicating effectively is one of these challenges, especially if plan deviations during field operations require robot explanation. However, challenges remain in developing robot capabilities suitable for teaming with humans. Autonomous robots have the potential to play a critical role in urban search and rescue (USAR) by allowing human counterparts of a response team to remain in remote, stable locations while the robots execute more dangerous work in the field.
