  • Publication number: 20220088796
    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.

  • Publication number: 20220088801
    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.

  • Publication number: 20210039250
    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.

  • Patent number: 10889004
    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.
