1.1 This terminology covers terms associated with Urban Search and Rescue (USR) Robotics. By providing a common and consistent lexicon, the purpose of this document is to facilitate communication between individuals who may be involved in the research, design, and deployment of robots for USR operations.

1.2 In order for the standard to be harmonious with the practices in the field, definitions have been drawn from the literature or other public sources when possible. When no definition is available, or definitions are in dispute, a consensus-based approach will be employed to resolve definitions and add them to the lexicon. The development of this standard is taking place in close coordination with the corresponding efforts in E54.08 and E54.92 to ensure comprehensive and consistent coverage.
