Abstract

A walk-about exoskeleton system can comprise an exoskeleton and a walk-about platform in support of the exoskeleton. The walk-about platform can be maneuverable about a ground surface. The walk-about platform can comprise a conveyance system operable with the walk-about platform. The conveyance system can be operable to facilitate movement of the walk-about platform about the ground surface. The walk-about platform can also comprise a bi-pedal locomotion zone defined, at least in part, by the walk-about platform. The bi-pedal locomotion zone can provide clearance for bi-pedal locomotion of an operator donning the exoskeleton.

First claim

What is claimed is:

1 . A walk-about exoskeleton system, comprising:
an upper-body robotic exoskeleton comprising at least one upper-body robotic limb that interacts with an arm of an operator and that facilitates augmented upper-body movements of the operator, the upper-body robotic limb comprising at least one powered joint actuatable in at least one degree of freedom; a walk-about platform in support of the exoskeleton, the walk-about platform being maneuverable about a ground surface, and comprising:
a conveyance system comprising a ground-contacting element, the conveyance system being operable with the walk-about platform, and to facilitate movement of the walk-about platform about the ground surface;
a walk-about base comprising first and second lateral members and a support bridge supported in an elevated position above the first and second lateral members to define an opening between the support bridge and the ground surface;
and
a bi-pedal locomotion zone defined, at least in part, by the walk-about platform that provides clearance for bi-pedal locomotion of an operator donning the exoskeleton, the lower-body of the operator being decoupled from the walk-about platform;
a mast extending up from the walk-about base;
a mast interface member moveably coupled to the mast; and
a torso member supported by the mast interface member, and in support of the exoskeleton; and
an operator interface supported by the torso member, the torso member and the operator interface being operable to rotate relative to the mast interface member about an axis of rotation at a torso-forebend joint,
wherein the bi-pedal locomotion zone extends through the opening, such that the clearance provided for the operator extends at least below the support bridge.

2 . The walk-about exoskeleton system of claim 1 ,
wherein the exoskeleton is supported by the mast so as to position the operator in the bi-pedal locomotion zone upon donning the exoskeleton.

3 . The walk-about exoskeleton system of claim 1 , wherein the exoskeleton is coupled to the mast via the torso interface member and the mast interface member.

4 . The walk-about exoskeleton system of claim 1 , wherein the exoskeleton is vertically adjustable along the mast.

5 . The walk-about exoskeleton system of claim 1 , wherein the relative rotation of the torso member and the mast interface member about the axis is powered by an actuator.

6 . The walk-about exoskeleton system of claim 1 , further comprising a winch system coupled between the mast and the exoskeleton, the winch system being operable to rotate the torso member relative to the mast interface member about the axis of rotation at the torso-forebend joint.

7 . The walk-about exoskeleton system of claim 1 , wherein the bi-pedal locomotion zone comprises an area defined, at least in part, by a plurality of ground-contacting elements in the form of ground-contacting rollers of the conveyance system that are disposed on the walk-about base, and wherein a center of gravity of the walk-about exoskeleton system is maintained within the area to avoid tipping during use.

8 . The walk-about exoskeleton system of claim 7 , further comprising a power source supported by the walk-about base at a position operable to maintain the center of gravity within the area to avoid tipping during use.

9 . The walk-about exoskeleton system of claim 8 , wherein the power source is supported by the walk-about base at a position rearward of the operator.

10 . The walk-about exoskeleton system of claim 7 ,
wherein the first and second lateral members define, at least in part, the bi-pedal locomotion zone; and the first and second lateral members each comprise a retractable extension operable to selectively extend and retract from the first and second lateral members, respectively.

11 . The walk-about exoskeleton system of claim 10 , wherein the ground-contacting rollers comprise front and rear ground-contacting rollers, the front ground contacting rollers being disposed on the retractable extensions of the first and second lateral members, respectively.

12 . The walk-about exoskeleton system of claim 11 , wherein the walk-about base comprises an actuator in each of the first and second lateral members operable to extend and retract the retractable extensions.

13 . The walk-about exoskeleton system of claim 11 , wherein the front ground contacting rollers each include an actuator operable to extend and retract the retractable extensions.

14 . The walk-about exoskeleton system of claim 1 , wherein the first and second lateral members extend outward from the support bridge below the exoskeleton, and wherein the first and second lateral members define, at least in part, the bi-pedal locomotion zone.

15 . The walk-about exoskeleton system of claim 1 , wherein the first and second lateral members each comprise front and rear rollers.

16 . The walk-about exoskeleton system of claim 1 , further comprising a counterweight that is operable with the walk-about base.

17 . The walk-about exoskeleton system of claim 16 , wherein the counterweight is adjustable so as to vary the center of gravity of the walk-about exoskeleton system.

18 . The walk-about exoskeleton system of claim 16 , wherein the counterweight comprises an extendable arm supported by the walk-about base, the extendable arm being extendable and retractable in a direction away from a direction of the first and second lateral members.

19 . The walk-about exoskeleton system of claim 18 , further comprising an actuator operable to facilitate extension and retraction of the extendable arm.

20 . The walk-about exoskeleton system of claim 1 , further comprising first and second forks extending from the first and second lateral members, respectively, the first and second forks being actuatable to carry a load.

21 . The walk-about exoskeleton system of claim 20 , wherein the first and second forks are operable to move from a stowed position to a deployed position.

22 . The walk-about exoskeleton system of claim 21 , wherein the first and second forks are retractable into the first and second lateral members.

23 . The walk-about exoskeleton system of claim 21 , wherein the first and second forks are rotatable relative to the first and second lateral members to move from the stowed position to the deployed position.

24 . The walk-about exoskeleton system of claim 1 , wherein the conveyance system is operably integrated with a remote navigation system via an interface that connects the walk-about exoskeleton to the remote navigation system, the remote navigation system configured to facilitate movement of the walk-about platform about the ground surface in at least one of a riding mode, a remote mode, or an autonomous mode.

25 . A walk-about platform operable to support a wearable exoskeleton, the walk about platform comprising:
a mast, a torso member supported by the mast, and an operator interface supported by the torso member; a robotic exoskeleton interface supported by the torso member, the robotic exoskeleton interface being operable to receive and support an upper-body robotic exoskeleton comprising at least one upper-body robotic limb that interacts with an arm of an operator and that facilitates augmented upper-body movements of the operator, the at least one upper-body robotic limb comprising at least one powered joint actuatable in at least one
