Abstract: Exemplary embodiments relate to improvements in soft robotic systems that permit a soft robotic end effector to be a self-contained system, without reliance on a tether to deliver inflation fluid to the actuator(s) of the end effector. According to some embodiments, a robotic system may be provided including a soft actuator and a hub. The body of the hub may include an integrated pressure source configured to supply inflation fluid through the actuator interface to the soft actuator. The pressure source may be, for example, a compressor (such as a twin-head compressor) or a reaction chamber configured to vaporize a fuel to create a high-temperature pressurized gas and deliver the pressurized gas to the actuator One or more accumulators may receive inflation fluid (or a partial vacuum) from the compressor over time, and store the inflation fluid under pressure, thus allowing actuation over a relatively short time period.

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 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 soft robotic gripper systems suited to grasping target objects in cluttered environments. Some embodiments provide extension rods, hinges, and/or rails that allow a soft robotic actuator to be extended towards or away from a robotic base and/or other actuators. Accordingly, a gripper including the actuator may be reconfigured into a size and/or shape that allows for improved access to the cluttered environment. Further embodiments relate to soft robotic gripper systems for supporting grasped objects during high acceleration movements using vacuum, gripper, and/or bellows devices. Still further embodiments relate to specialized grippers for manipulating food items.

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.
