Abstract

The present disclosure provides a soft poly-limb system, comprising a first actuator segment, a second actuator segment, and a third actuator segment forming the soft poly-limb. Each of the first actuator segment, the second actuator segment, and the third actuator segment may comprise a plurality of ring reinforced actuators. The soft poly-limb system may further comprise a control system whereby a user may control the soft poly-limb.

Claims (25)

1. A soft poly-limb system, comprising:

a first actuator segment, a second actuator segment, and a third actuator segment forming the soft poly-limb, wherein each of the first actuator segment, the second actuator segment, and the third actuator segment comprise a plurality of ring reinforced actuators;

a control system whereby a user may control the soft poly-limb;

a backpack mount coupled to the first actuator segment; and

a storage pouch coupled to the backpack mount,

wherein the first actuator segment, the second actuator segment, and the third actuator segment are storable within the pouch when not in use,

wherein each ring reinforced actuator is fluid-driven and comprises a plurality of rings dispersed along an external surface of an actuator body,

wherein the plurality of rings are configured to restrain radial expansion and promote linear extension motion, and

wherein the soft poly-limb is configured with at least nine degrees of freedom.

2. The system of claim 1 , wherein the backpack mount comprises at least two mounting locations for the first actuator segment.

3. The system of claim 2 , wherein the plurality of mounting locations comprises an upper-rear right mounting location, an upper-rear left mounting location, a middle-rear right mounting location, a middle-rear left mounting location, a lower-rear right mounting location, and a lower-rear left mounting location.

4. The system of claim 1 , wherein each actuator segment is tapered such that the soft poly-limb is tapered.

5. The system of claim 1 , wherein each ring reinforced actuator has a first diameter at one end and a second, smaller diameter at a second, opposite end.

6. The system of claim 1 , wherein the system is wearable by a user to provide enhanced object manipulation capabilities to the user.

7. The system of claim 1 , further comprising an end-effector coupled to the third actuator segment.

8. The system of claim 1 , wherein the system comprises at least five actuator segments, or at least seven actuator segments, or at least ten actuator segments.

9. A method of manufacturing a soft poly-limb comprising:

forming an actuator body from a first mold;

coupling one or more rings to the actuator body to form a ring reinforced actuator;

arranging a plurality of ring reinforced actuators in a second mold;

forming an actuator segment from the second mold; and

coupling a plurality of actuator segments to form the soft poly-limb.

10. The method of claim 9 , wherein coupling a plurality of actuator segments comprises coupling the plurality of actuator segments together via at least one modular connector cap.

11. The method of claim 9 , wherein the first mold comprises at least one frame segment, a core, and a first cap.

12. The method of claim 9 , wherein arranging the plurality of ring reinforced actuators comprising arranging the plurality of ring reinforced actuators in an equilateral triangle prism.
