A doorway system for a robotic vehicle that accesses a separated area through a barrier that has a doorway formed through it. The system includes a wireless transmitter that transmits an electronic signal from the robotic vehicle, and a door movably disposed within the doorway, between a closed position and an open position. A doorway device with a wireless receiver that is coupled to a locking mechanism is configured to selectively engage and lock the door at the closed position, and unlock the door upon receipt of the electronic signal by the wireless receiver. Movement of the robotic vehicle toward the doorway device enables communication of the electronic signal from the wireless transmitter to the wireless receiver. Upon passage of the robotic vehicle through the doorway to the separated area, and return of the door to the closed position, the controller controls the locking mechanism to engage and lock the door.
