Abstract

A deployable docking station for supporting at least one mobile robot is provided. The deployable docking station includes a housing and an anchor connected to the housing. The anchor can engage with a surface to maintain the position of the deployable docking station. The deployable docking station is further configured to couple and decouple with the at least one mobile robot. The deployable docking station can be configured to selectively alternate between a first and second condition. In the first condition, the deployable docking station is coupled with the at least one mobile robot and the at least one mobile robot can transport the deployable docking station to a desired location on the surface. In the second condition, the deployable docking station is de-coupled from the at least one mobile robot.

a housing; and

an anchor connected to the housing configured to selectively engage with the surface,

wherein the deployable docking station is configured to alternate, selectively, between a first condition in which the at least one mobile robot and the deployable docking station are engaged via the coupling and the anchor is disengaged from the surface, wherein in the first condition the at least one mobile robot is configured to transport the deployable docking station to a desired location along the surface, and a second condition in which the at least one mobile robot and the deployable docking station are disengaged and the anchor is engaged with the surface, wherein in the second condition the at least one mobile robot is configured to move along the surface without the deployable docking station and the deployable docking station remains stationary at the desired location along the surface.

2. The deployable docking station of claim 1, wherein the deployable docking station further comprises a control module comprising a storage medium and a processor operatively coupled to the storage medium, the processor being configured to execute one or more software modules stored on the storage medium, wherein the control module is connected to the housing and configured to receive and transmit data from the at least one mobile robot.

3. The deployable docking station of claim 2, wherein the control module is configured to selectively alternate the deployable docking station between the first condition and the second condition via a signal from the control module to the at least one mobile robot.

4. The deployable docking station of claim 1, further comprising:

a tether connected to the housing, wherein the at least one resource is provided by the tether.

5. The deployable docking station of claim 1, further comprising:

an on-board supply source, wherein the at least one resource is provided by the on-board supply source.

6. The deployable docking station of claim 1, wherein the at least one resource is a consumable resource.

7. The deployable docking station of claim 6, wherein the consumable resource comprises at least one of power, air, pressurized air, gas, oil, fuel, paint or water.

8. The deployable docking station of claim 1, wherein the at least one resource is a nonconsumable resource.

9. The deployable docking station of claim 8, wherein the nonconsumable resource comprises at least one of a communication resource or an environmental protection feature.

10. The deployable docking station of claim 9, wherein the communication resource is provided via a communication protocol comprising at least one of Wi-Fi, RF, Zigbee, Serial UART, SPI, or i2c.

11. The deployable docking station of claim 1, wherein the deployable docking station further comprises at least one of a Wi-Fi router, a signal repeater, or an access point.

12. The deployable docking station of claim 1, wherein the engagement between the anchor and the surface is at least one of magnetic adhesion, electromagnetic adhesion, vacuum adhesion, suction adhesion, electrostatic adhesion, dry adhesion, or friction-based adhesion.

13. The deployable docking station of claim 1, wherein the anchor comprises one or more permanent magnets.

14. The deployable docking station of claim 13, further comprising an adjustable mount on the anchor, wherein positioning of the one or more permanent magnets on the anchor is adjustable.

15. The deployable docking station of claim 13, wherein the deployable docking station further comprises an electro-magnet connected to the housing to counteract the effect of the one or more permanent magnets to disengage the anchor from the surface.

16. The deployable docking station of claim 13, wherein the magnetic flux circuit created by the one or more permanent magnets can be short circuited via a signal from the deployable docking station to disengage the anchor from the surface.
