  • Patent number: 10232383
    Abstract: A process for sorting materials using material-selective electroadhesive grippers is disclosed. At least one of an electroadhesive surface or a plurality of articles is manipulated such that multiple ones of the plurality of articles are at least intermittently proximate the electroadhesive surface. Voltage is applied to one or more electrodes in the electroadhesive surface to thereby cause the electroadhesive surface to selectively adhere to a subset of the plurality of articles based on the subset of the plurality of articles having different material properties than others of the plurality of articles. While the voltage is applied, the electroadhesive surface is moved with respect to the others of the plurality of articles to thereby separate the subset of the plurality of articles from the others of the plurality of articles.

  • Patent number: 10065326
    Abstract: Acquisition or pick-up tools that themselves aid in improving the ease with which images of an acquired substrate may be captured, and methods of operating such pick-up tools, are provided. The pick-up tools may include a pick-up surface adapted to interface with a foreign substrate and a light source integrated with the pick-up tool such that light emitted from the light source passes through the pick-up surface to the foreign substrate when the foreign substrate is temporarily coupled with the pick-up surface to create a silhouette of the foreign substrate. A vision system may be adapted for capturing the silhouette of the foreign substrate when the foreign substrate is temporarily coupled with the pick-up surface. The substrate pick-up surface may be formed of one of a transparent, a semi-transparent, or a translucent material such that light may at least partially pass there through.

  • Publication number: 20170036798
    Abstract: Provided herein are solutions to automated material handling comprising systems that allow automated “each pick handling” without requiring the complexity of robotic grasping. Numerous examples of pre-configurable and reconfigurable transport containers, partitioning devices, and automated container configuration stations are described in addition to methods of use and associated material handling systems that utilize such containers. Further described are containers that are individually configured or customized according to specific lot sizes to more efficiently and optimally contain, store and distribute articles as a component of a picking system. Configurable containers or “totes” may be customized on a per-order basis to create optimally configured containers that maximize the use of space in a container, on a single-item-per-space basis, regardless of item quantity, size or volume, by customizing the size of each space within a container or tote.

  • Patent number: 9563274
    Abstract: The present invention relates to an adaptable input/output device. One embodiment of a hardware device for facilitating an interaction between a computing system and a user includes: an interaction surface for supporting the interaction, a single actuator capable of driving a first region of the interaction surface, and a first selective clamping mechanism capable of restricting movement of one or more second regions of the interaction surface that partly intersect the first region, wherein a displacement of one or more desired portions of the interaction surface is dynamically controllable.

  • Publication number: 20160318190
    Abstract: Automated manufacturing often requires reliable tools for acquiring or moving items in a manufacturing process. An electroadhesive gripper utilizes electroadhesive surfaces to acquire and move items from one step in a process to another. An electroadhesive surface can include electrodes that are configured to induce an electrostatic attraction with nearby objects upon application of voltage to the electrodes. Systems described herein also employ a load-bearing frame that is coupled to an electroadhesive gripping surface. Components of these electroadhesive systems may be configured to be modular in construction to simplify construction and maintenance. Some components may be disposable or require more frequent repair than other components. Modular assembly and component construction simplifies maintenance and reduces overall costs of operation.

  • Patent number: 9401668
    Abstract: An electroadhesive device includes an outer surface adapted to interface with a surface of a foreign substrate, a plurality of electrodes, and a semi-conductive insulation material disposed adjacent to at least one of the electrodes. Each electrode has a respective conductive volume and is configured to apply a voltage at a respective location of the outer surface, and the difference in voltage between applied voltages includes an electrostatic adhesion voltage that produces an electrostatic force between the device and the substrate that is suitable to maintain a current position of the device relative to the substrate. The insulation material can be polyurethane or any other suitable material having a resistance of about 109 to 1012 ohms*m. The insulation material effectively operates to expand the conductive volume of the electrodes when they are actuated.
