  • Patent number: 11110616
    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.

  • Patent number: 11072080
    Abstract: Exemplary embodiments relate to unique structures for robotic end-of-arm-tools (EOATs). In particular, exemplary embodiments provide structures allowing a displacement fluid to be discharged from a distal end of a robotic finger. The discharge may be used to displace a target object, such as an object that is adjacent to another blocking object or the side of a container. After the target object is displaced, the EOAT may be better able to maneuver into a gripping posture and may be able to secure a better grasp on the target object.

  • Patent number: 11059188
    Abstract: Exemplary embodiments relate to a fastener suitable for industrial tasks. Some embodiments include a sealing surface sized so that an outer surface of a sealing ring is located at approximately the same diameter as the fastener head, thus reducing ingress risk for foreign contaminants. Further embodiments provide a centering pilot to improve sealing consistency and quality. Some embodiments provide an angled flange on the fastener head to lift tightening tools away from the surface to which the fastener is being applied, and to shed liquids readily. The portion of the head that receives the tightening tools may be relatively small (approximately the same diameter as the fastener's threaded shaft) to reduce the risk of over-torquing. A bearing surface of the fastener may be located below the sealing ring (towards the threaded shaft) to prevent the fastener from marring the unsealed surface to which the fastener is being applied.

  • Patent number: 11045959
    Abstract: Exemplary embodiments relate to unique structures for robotic end-of-arm-tools (EOATs). According to some embodiments, two or more fingers or actuators may be present on an EOAT, and the actuators may be configured to move (together or separately) to adjust the spacing between the actuators. Some aspects involve techniques for extending and/or retracting a vacuum cup present on the EOAT. Further embodiments, which may be used separately or in conjunction with the previously-described embodiments, apply a secondary inner grip pad to provide a secondary gripping mode for the EOAT. These embodiments may be particularly advantageous when the actuators are soft robotic actuators and the inner grip pad is a relatively more rigid structure than the actuators.

  • Patent number: 10946531
    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.

  • 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.

  • Patent number: 10850391
    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: 10702992
    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.

  • Patent number: 10668629
    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.

  • Patent number: 10632625
    Abstract: Robotic grippers have been employed to grasp and manipulate target objects. One task posing relatively unique problems is the handling of meat products, which can be difficult to grasp with a conventional gripper due to the surface texture and malleability of the meat, among other factors. This is particularly problematic when the meat product includes a bone, which has different properties from the relatively malleable meat surrounding it. Exemplary embodiments described herein provide robotic grippers having one or more fingers and a layered plate. The layered structure defines grooves sized and configured to lead in and capture the bone structure of the meat product. The grooves provide a backstop for the meat as well as preventing rotation or translation of the bone structure, thus allowing a firm grasp to be secured on the meat product.
