The robotic devices are associated with one or more charging stations. The charging stations may be located at predefined home base or reference locations in the property. The robotic devices may be configured to navigate to the charging stations after completion of tasks needed to be performed for the monitoring system 500. For instance, after completion of a monitoring operation or upon instruction by the control unit 510, the robotic devices may be configured to automatically fly to and land on one of the charging stations. In this regard, the robotic devices may automatically maintain a fully charged battery in a state in which the robotic devices are ready for use by the monitoring system 500.
The charging stations may be contact based charging stations and/or wireless charging stations. For contact based charging stations, the robotic devices may have readily accessible points of contact that the robotic devices are capable of positioning and mating with a corresponding contact on the charging station. For instance, a helicopter type robotic device may have an electronic contact on a portion of its landing gear that rests on and mates with an electronic pad of a charging station when the helicopter type robotic device lands on the charging station. The electronic contact on the robotic device may include a cover that opens to expose the electronic contact when the robotic device is charging and closes to cover and insulate the electronic contact when the robotic device is in operation.
