Abstract:
A compact, portable, easily implemented soft robotic orthopedic stabilization device for adjustably and selectively stabilizing a fractured or otherwise injured limb of a patient while providing convenient access to portions of the limb for treatment thereof.
Abstract:
Exemplary embodiments describe soft robotic actuators for medical use, such as during surgeries and other medical procedures. According to one embodiment, a soft robotic incision retractor is provided. According to another embodiment, a soft robotic body tissue retractor is provided. The incision retractor and body tissue refractor may be used together, for example by using the incision retractor to hold open an incision while the body tissue retractor manipulates biological matter or an object accessible through the incision. Described embodiments offer the ability to conform to a given space, reduced risk of damage to surrounding structures as compared to traditional retractors, the ability to deliver varying amounts of force, the ability to be made from medically safe materials, and the potential for re-use or disposability.
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.
Abstract:
A soft robotic actuator is disclosed. The actuator includes a first portion with a substantially constant profile and a second portion with a regularly varying profile, and bends in a pressure-dependent fashion as the internal pressure within the actuator is increased or decreased.
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:
Exemplary embodiments provide modular robotic systems that allow one or more operation parameters of a robotic actuator, or group of actuators, to be dynamically configured or reconfigured. The operation parameters may be, for example, the X, Y, and/or Z position of the actuator or group of actuators with respect to other actuators, the arrangement of the actuator(s) into an array or matrix, the rotation or pitch of an actuator, the distance between actuators, the grip strength or grip surface of an actuator, etc. Accordingly, the same robotic manipulator(s) may be used for multiple purposes in multiple different contexts, manipulators can be swapped out on-the-fly, and robotic systems may be dynamically reconfigured to perform new tasks.
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:
Exemplary embodiments relate to various improvements in soft robotic actuators, and more specifically the integration of stiff or rigid bodies into soft actuators to provide adjustable gripping behaviors. These actuators may be used as robotic end effectors to, for example, automate material handling processes. According to some embodiments, the actuators may be deployed in combination with a static or dynamic rigid structure, such as a rod. The rigid structure may extend beside or within the actuator. Multiple rigid structures may be deployed on the sides of an actuator, or multiple actuators may be deployed on the sides of a rigid structure. In further embodiments, an array or matrix of actuators may be integrated into a rigid structure, providing a low-profile gripper that can be maneuvered into tight spaces.
Abstract:
Exemplary embodiments relate to improvements in robotic systems to reduce biological or chemical harborage points on the systems. For example, in exemplary embodiments, robotic actuators, hubs, or entire robotic systems may be configured to allow crevices along joints or near fasteners to be reduced or eliminated, hard corners to be replaced with rounded edges, certain components or harborage points to be eliminated, shapes to be reconfigured to be smoother or flat, and/or or surfaces to be reconfigurable for simpler cleaning.
Abstract:
Exemplary embodiments relate to various improvements in soft robotic actuators, and techniques for manufacturing the improvements. For example, techniques for manufacturing a rigidizing layer for reinforcing a soft robotic actuator is provided. In another embodiment, a soft robotic actuator having integrated sensors is described. A flexible electroadhesive pad for achieving a conformal grip is also described. Still further, exemplary embodiments provide hydraulically-actuated soft robotic grippers, which allows for a reduction in the size of the actuation system and improved underwater operation.
