Drury1 and Holly A. Yanco2 The MITRE Corporation Bedford MA University of Massachusetts Lowell Lowell MA USA 1. Introduction In remote robot operations the human operator s and robot s are working in different locations that are not within line of sight of each other. In this situation the human s knowledge of the robot s surroundings location activities and status is gathered solely through the interface. Depending on the work context having a good understanding of the robot s state can be critical. Insufficient knowledge in an urban search and rescue US AR situation for example may result in the operator driving the robot into a shaky support beam causing a secondary collapse. While the robot s sensors and autonomy modes should help avoid collisions in some cases the human must direct the robots operation. If the operator does not have good awareness of the robot s state the robot can be more of a detriment to the task than a benefit. The human s comprehension of the robot s state and environment is known as situation awareness SA . Endsley developed the most generally accepted definition for SA The perception of elements in the environment within a volume of time and space Level 1 SA the comprehension of their meaning Level 2 SA and the projection of their status in the near future Level 3 SA Endsley 1988 . Drury Scholtz and Yanco 2003 redefined this definition of situation awareness to make it more specific to robot operations breaking it into five categories human-robot awareness the human s understanding of the robot human-human awareness robot-human awareness the robot s information about the human robot-robot awareness and the humans overall mission awareness. In this chapter we focus on two of the five types of awareness that relate to a case in which one human operator is working with one robot human-robot awareness and the human s overall mission .
