Abstract: A method of confining a robot in a work space includes providing a portable barrier signal transmitting device including a primary emitter emitting a confinement beam primarily along an axis defining a directed barrier. A mobile robot including a detector, a drive motor and a control unit controlling the drive motor is caused to avoid the directed barrier upon detection by the detector on the robot. The detector on the robot has an omnidirectional field of view parallel to the plane of movement of the robot. The detector receives confinement light beams substantially in a plane at the height of the field of view while blocking or rejecting confinement light beams substantially above or substantially below the plane at the height of the field of view.

Abstract: A directed beam emitter system for robot navigation in which a light beam emitter emits a modulated directed light beam of a first modulation and an omnidirectional diffuse light region emitter emits a modulated diffuse light region of a second modulation. The modulated directed light beam and the modulated diffuse light region overlap in a plane parallel to ground level such that a light beam receiver on a robot may detect either one or both of the modulated directed light beam and the modulated diffuse light region. The light beam emitter is responsive to a control system used to control one or more light beam emitters.
