Embodiment Construction

[0025] Embodiments relate to robotic systems designed or configured to provide self-contained soft robotic end effector systems.

[0026] A soft robotic end-of-arm tool (EOAT) can be mounted on the end of a robotic manipulator. These manipulators have a specified payload capacity and they are able to maneuver without negatively affecting the dynamics of the arm. This permissible payload size, weight and moment of inertia are usually many times smaller than the control manipulator itself, so that a smaller achievable payload results in a disproportionately increased installation capacity and space requirement. Furthermore, after the installation of the soft robot EOAT, sufficient capabilities for manipulating the target (the object to be moved or re-orientated) must be preserved. A self-contained soft robotic end-effector system must be highly efficient in its design to ensure that its ultimate physical performance is comparable to that of conventional tethered soft robotic en...

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.

Description

[0001] related application [0002] This application claims priority to US Provisional Patent Application Serial No. 62 / 199,029, filed July 30, 2015, entitled "Standalone Soft Robotic Gripper System." The content of the above application is incorporated herein by reference. Background technique [0003] Robotic systems may be employed in a number of different environments and may be required to perform a variety of different tasks. Robots typically use robotic manipulators such as individual actuators, grippers, or end effectors to manipulate objects around them. [0004] Recently, soft robotic actuators have been adopted in many settings. Unlike traditional hard robotic actuators, which are formed from metal or hard plastic, soft robotic actuators can be constructed from elastic materials such as rubber, or in an accordion-like configuration that expands, stretches, twists, and / or bends under pressure Arranged thin-walled plastic, or other suitable relatively soft materia...
