Abstract: A hub assembly for coupling different grasper assemblies including a soft actuator in various configurations to a mechanical robotic components are described. Further described are soft actuators having various reinforcement. Further described are and soft actuators having electroadhesive pads for improved grip, and/or embedded electromagnets for interacting with complementary surfaces on the object being gripped. Still further described are soft actuators having reinforcement mechanisms for reducing or eliminating bowing in a strain limiting layer, or for reinforcing accordion troughs in the soft actuator body.

Abstract: A soft robot having an integrated electrical component includes an expandable or collapsible body, the body comprising an inlet that is configured to communicate with a fluid source and a flexible strain limited layer secured to a portion of the expandable or collapsible body, wherein the strain limited layer includes at least one electrical component.

Abstract: A limb stabilization device is described, including: two or more collars configured to surround a limb and apply a pressure to the limb at or below a threshold pressure, wherein the collar comprises a pressurized bladder or a compressed memory foam to conform the collar to the limb; at least one beam connecting the two or more collars to support the limb; and optionally a pressure modulator configured to regulate the pressure of the bladder to be at or below a threshold pressure.

Abstract: A soft material retractor includes at least two soft actuators, each actuator having at least one pressurizable interior space, wherein the actuator has a first flexible resting state and a second stiffer pressurized state; and a flexible sheet spanning the actuators such that the actuators can be spaced apart from each other by a distance selected to displace a volume of material of a body cavity. The retractor can be uses for holding open wounds or incisions, with trochars, or to displace anatomical features such as organs within a body cavity.

Abstract: An elastically-deformable, conductive composite using elastomers and conductive fibers and simple fabrication procedures is provided. Conductive elastomeric composites offer low resistance to electrical current and are elastic over large (>25%) extensional strains. They can be easily interfaced/built into structures fabricated from elastomeric polymers.

Abstract: A composite structural element is described, including: a first laminate layer comprising a plurality of first material layers; a second laminate layer comprising a plurality of second material layers; and an inflatable bladder configured for connection with a fluid inflation or deflation source and disposed in-between the first and second laminate layers.

Abstract: A soft conformal compression device for treatment of a wound on a patient's limb, the device including a network of pneumatic actuators and a wound dressing. The pneumatic actuators may be activated by applying a source of a gas to an inlet on the device, which may cause the device to curve, bend, or otherwise deform in a predetermined manner to encircle a patient's limb and urge the wound dressing toward the wound.

Abstract: A soft robotic instrument that is capable of changing its form factor (e.g., expanding and contracting) during use to facilitate minimally invasive surgery. The instrument may be formed wholly or partly of an elastomeric, electrically insulating material for mitigating the risk of injuring tissue and for mitigating the risk of electrical arcing during electrosurgery.
