Abstract

A ground vehicle and a method for articulating a payload module for mobility assist are disclosed. The ground vehicle comprises a chassis; and a payload module capable of articulating relative to the chassis to assist the mobility of the ground vehicle. The method comprises articulating a payload module relative to a chassis.

Claims

1. A ground vehicle, comprising:

a chassis, the chassis defining a payload bay; and

a payload module capable of articulating into and out of the payload bay and relative to the chassis to assist mobility of the ground vehicle.

6. The ground vehicle of claim 1, wherein the payload module articulates by rotating.

7. The ground vehicle of claim 6, wherein the payload module rotates through 180°

.

8. The ground vehicle of claim 7, wherein the rotation is ±

90°

relative to a centerline of the chassis.

9. The ground vehicle of claim 1, wherein the payload module articulates to push against the ground.

10. The ground vehicle of claim 1, further comprising a payload housed in the payload module.

13. The ground vehicle of claim 1, further comprising an articulable coupling between the payload module and the chassis.

17. A method for assisting mobility of a ground vehicle, comprising articulating a payload module relative to a chassis, including into and out of a payload bay defined by the chassis.

18. The method of claim 17, wherein articulating the payload module includes pushing against the ground.

19. The method of claim 17, wherein articulating the payload module includes rotating the payload module.

21. The method of claim 19, wherein rotating the payload module includes rotating the payload module through 180°

.

22. The method of claim 21, wherein rotating the payload module through 180°

comprises rotating the payload module ±

90°

relative to a centerline of the chassis.

29. An articulable payload module coupling.

30. The articulable payload module coupling of claim 29, wherein the articulable couple is capable of articulating through 180°

.

31. The articulable payload module coupling of claim 29, wherein the articulable payload module coupling includes:

a splined, sliding dog clutch; and

a motor.

32. The articulable payload module of claim 31, further including a rotary encoder.

33. The articulable payload module of claim 29, including a rotary encoder.

34. A ground vehicle, comprising:

a chassis; and

a payload module capable of articulating relative to the chassis to assist mobility of the ground vehicle by pushing against the ground.

35. The ground vehicle of claim 34, wherein the chassis defines a payload bay from which the payload module articulates.

36. The ground vehicle of claim 34, wherein the payload module articulates by rotating.

37. The ground vehicle of claim 34, further comprising a payload housed in the payload module.

38. The ground vehicle of claim 34, further comprising an articulable coupling between the payload module and the chassis.

39. A method for assisting mobility of a ground vehicle, comprising articulating a payload module relative to a chassis to push against the ground.

40. The method of claim 39, wherein articulating the payload module includes rotating the payload module.

41. The method of claim 40, wherein rotating the payload module includes rotating the payload module out of a payload bay.
