    Abstract: An electroadhesive gripping platform includes one or more electrodes. A power supply is configured to apply voltage to the one or more electrodes in the electroadhesive platform via one or more terminals. A controller is configured to operate the electroadhesive gripping platform to selectively adhere to items loaded thereon and thereby enhance traction control over such items. The controller can control the power supply to apply a voltage to the one or more electrodes in the electroadhesive platform to thereby cause the electroadhesive platform to adhere to an item disposed on the electroadhesive platform such that the item resists moving with respect to the electroadhesive platform. The controller can also control the voltage supply to reduce the voltage applied to the one or more terminals such that the item moves with respect to the electroadhesive platform.

    Abstract: A twisted string actuator system includes a motor generating rotary motion of a rotor and a twisted string comprised of a pair of cords. One end of the twisted string is attached to the rotor and an opposite end of the twisted string is coupled to a load. The cords are twisted about each other for a first section of the twisted string and untwisted for a second section of the twisted string. A cord guide is fixedly disposed between the cords. The first and second sections of the twisted string are on a first side and second side, respectively, of the cord guide. Rotary motion of the rotor in one direction operates to twist the pair of cords on the first side of the cord guide while pulling a portion of the pair of cords from the second side of the cord guide into the first side.

    Abstract: An electroadhesive gripping system includes a vacuum-augmented gripper. The gripper can include an electroadhesive surface associated with one or more electrodes and a load-bearing backing structure coupled to the electroadhesive surface. The backing couples to the backside of the electroadhesive surface so as to at least partially define a shape of the electroadhesive surface. The backing is configured to flex between a curled shape and an uncurled shape. A spreading arm is configured to apply force to the backing so as to flex the backing from the curled shape to the uncurled shape. When positioned next to a substrate, the uncurling motion of the backing can cause the electroadhesive surface to become vacuum sealed to the substrate. A power supply can be configured to apply voltage to the electroadhesive surface.
