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.
