1. A robot system comprising:

  • a portable barrier signal device comprising an emitter configured to emit, primarily along an axis, an optical confinement signal to form a directed barrier; and

    a mobile robot comprisingat least two wheels,two motors, each motor being connected to a wheel of the at least two wheels for moving the robot on a surface,a cleaner configured to clean the surface as the robot moves on the surface,a detector configured to detect the directed barrier formed by the optical confinement signal, the detector having an omnidirectional field of view such that the detector detects the directed barrier independent of an orientation of the robot relative to the axis defining the directed barrier, anda control unit to execute operations comprisingdetermining whether the detector detects the directed barrier, and,upon determining that the detector detects the directed barrier, initiating one or more operations to move the robot until the optical confinement signal is undetected by the detector.
