Abstract

Systems, devices, and methods are described for providing, among other things, a wheelchair-assist robot for assisting a wheelchair user with everyday tasks or activities at work, at home, and the like. In an embodiment, the mobile wheelchair-assist robot includes a wheelchair interface component configured to exchange control information with a wheelchair controller. In an embodiment, a wheelchair-assist robot mount assembly is provided for, among other things, electrically and physically coupling a wheelchair-assist robot to an associated wheelchair.

First claim

What is claimed is:

1. A flying wheelchair-assist robot, comprising:
a wheelchair interface component operable to exchange control information with a wheelchair client device; and
a rotorcraft structure operably coupled to the wheelchair interface component, the rotorcraft structure including one or more rotors for generating lift.

2. The flying wheelchair-assist robot of claim 1 , wherein the rotorcraft structure includes a plurality of rotary wings.

3. The flying wheelchair-assist robot of claim 1 , further comprising:
an electronic surveillance payload.

4. The flying wheelchair-assist robot of claim 3 , wherein the electronic surveillance payload includes one or more image sensors.

5. The flying wheelchair-assist robot of claim 3 , wherein the electronic surveillance payload includes one or more acoustic sensors.

6. The flying wheelchair-assist robot of claim 3 , wherein the electronic surveillance payload includes one or more electromagnetic energy sensors.

7. The flying wheelchair-assist robot of claim 3 , wherein the electronic surveillance payload includes at least one of a receiver, a transmitter, and a transceiver.

8. The flying wheelchair-assist robot of claim 3 , wherein the electronic surveillance payload includes one or more components configured to provide travel route status information based on one or more captured images.

9. The flying wheelchair-assist robot of claim 3 , wherein the wheelchair interface component includes circuitry configured to generate one or more navigation control commands to vary one or more of propulsion, braking, or steering of an associated wheelchair based on at least one input from a component associated with the electronic surveillance payload.

10. The flying wheelchair-assist robot of claim 1 , further comprising:
a fastening structure for removably attaching the flying wheelchair-assist robot to a wheelchair.

11. The flying wheelchair-assist robot of claim 1 , further comprising:
a fastening structure having a power interface, the fastening structure dimensioned and configured to removably attach the flying wheelchair-assist robot to a wheelchair, and to electrically couple the flying wheelchair-assist robot to a wheelchair power supply.

12. The flying wheelchair-assist robot of claim 1 , wherein the wheelchair interface component includes circuitry configured to communicate one or more navigation control commands to vary one or more of propulsion, braking, or steering of an associated wheelchair.

13. The flying wheelchair-assist robot of claim 1 , further comprising:
an image capture component.

14. The flying wheelchair-assist robot of claim 13 , wherein the image capture component includes one or more object sensors and is configured to maintain the flying wheelchair-assist robot at a target separation from an associated wheelchair.

15. The flying wheelchair-assist robot of claim 13 , wherein the image capture component is configured to survey a target region.

16. The flying wheelchair-assist robot of claim 15 , wherein the image capture component is configured to generate one or more parameters associated with the target region responsive to one or more inputs from the wheelchair interface component.

17. The flying wheelchair-assist robot of claim 15 , wherein the image capture component is configured to generate one or more parameters associated with the target region responsive to one or more inputs indicative of an associated wheelchair route.

18. The flying wheelchair-assist robot of claim 15 , wherein the image capture component is configured to select the target region based on at least one of an associated wheelchair orientation, an associated wheelchair position, and an associated wheelchair route.

19. The flying wheelchair-assist robot of claim 13 , wherein the image capture component includes circuitry for capturing three-dimensional images.

20. The flying wheelchair-assist robot of claim 13 , wherein the image capture component comprises a pan tilt zoom (PTZ) camera.

21. The flying wheelchair-assist robot of claim 1 , further comprising:
an autonomous navigation component.

22. The flying wheelchair-assist robot of claim 1 , further comprising:
a transfer arm assembly connected to a payload-support structure, the transfer arm assembly configured for autonomous transfer of a payload to and from the payload-support structure.

23. The flying wheelchair-assist robot of claim 1 , further comprising:
one or more speakers.

24. The flying wheelchair-assist robot of claim 1 , further comprising:
circuitry for providing an audio signal indicative of a presence, arrival, or imminent arrival of an associated wheelchair.

25. The flying wheelchair-assist robot of claim 1 , further comprising:
one or more memories having wheelchair travel-route information stored thereon.

26. The flying wheelchair-assist robot of claim 1 , further comprising:
one or more memories having geographical information associated with a wheelchair travel route stored thereon.
