Abstract: Exemplary embodiments provide enhancements for soft robotic actuators. In some embodiments, angular adjustment systems are provided for varying an angle between an actuator and the hub, or between two actuators. The angular adjustment system may also be used to vary a relative distance or spacing between actuators. According to further embodiments, rigidizing layers are provided for reinforcing one or more portions of an actuator at one or more locations of relatively high strain. According to further embodiments, force amplification structures are provided for increasing an amount of force applied by an actuator to a target. The force amplification structures may serve to shorten the length of the actuator that is subject to bending upon inflation. According to still further embodiments, gripping pads are provided for customizing an actuator's gripping profile to better conform to the surfaces of items to be gripped.

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 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 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: Exemplary embodiments relate to pressurizable housings for a soft robotic actuator. The pressurized housings may be divided into an upper chamber in fluid communication with an internal void of the actuator, and a lower chamber connected to an inlet and an outlet. The upper chamber and lower chamber may be separated by a piston. By supplying a fluid to the lower chamber via the inlet, the piston is moved into the space previously occupied by the upper chamber, which reduces the volume of the upper chamber and increases the pressure in the internal void. This action allows the actuator to be rapidly inflated, and further simplifies the pressurization system and reduces its weight.

The embodiments may be used to prevent deformation of grasped objects; detect grasping, collision, and releasing objects; and other operations with a rapid servo-pneumatic response.

Abstract: Various stabilization devices for a robotic end of arm tool, such as a robotic gripper, are described. The stabilization device is provided in a palm area of the end of arm tool and serves as a backstop against which actuators of the end of arm tool can push a compliant or slick target object. The stabilization device may take many any of a variety of shapes, depending on the application. Based on the shape of the stabilization device and the action of the robotic gripper on the target object, the target object can be moved or rotated in a more stable configuration, thus allowing the actuators to apply less force while still maintaining a firm grasp of the object.
