Abstract
The disclosure relates to a system and/or method to create or otherwise define one or more virtual barriers for confining or controlling an autonomous robotic device substantially within one or more portion of one or more selected working areas, for example, to prohibit entrance of certain areas. The system and/or method may use a set of beacon transmitters that emit time-stamped signals, which are received by one or more robots and used to calculate the robotic device's distance from such beacons.
