  • Patent number: 11014804
    Abstract: Systems and methods for fabricating 3D soft microstructures. The system comprises injecting a pressurized, curable liquid into certain structural layers induces folding and allows the 2D structures to reconfigure into a 3D form In addition to the injection of a curable liquid that permanently reconfigures the structure of the system, in an embodiment this method also allows for the injection of other liquids into certain actuator layers that enable motion in certain portions of the system Furthermore, the system allows for handling of colored fluids that are passed to visualization layers. The method of creating such a system depends on taking advantage of laser machining of the individual layers to influence the behavior of how different portions bend and move.

  • Patent number: 10689044
    Abstract: A pneumatically powered, fully untethered mobile soft robot is described. Composites consisting of silicone elastomer, polyaramid fabric, and hollow glass microspheres were used to fabricate a sufficiently large soft robot to carry the miniature air compressors, battery, valves, and controller needed for autonomous operation. Fabrication techniques were developed to mold a 0.65 meter long soft body with modified Pneumatic network actuators capable of operating at the elevated pressures (up to 138 kPa) required to actuate the legs of the robot and hold payloads of up to 8 kg. The soft robot is safe to handle, and its silicone body is innately resilient to a variety of adverse environmental conditions including snow, puddles of water, direct (albeit limited) exposure to flames, and the crushing force of being run over by an automobile.

  • Patent number: 10668825
    Abstract: An Engine Start and Battery Support Module for a vehicle is provided that utilizes a bank of Ultra Capacitors (UCs) charged with or without running the vehicle's alternator to levels that support both engine starting assistance and hotel load support. The UCs' per-cell charge can be adjusted and raised during periods of low temperatures and even higher during ultralow temperatures. The adjustment, which can be dynamic and/or automatic, increases the UC energy storage capability. Further, the release of energy from the UCs is controlled by a pulse width modulation (PWM) controller based on the DC bus voltage. The UCs can be charged either from an onboard DC/DC converter, an AC hook up, or from smartly switching the banks of UCs between parallel and serial configurations.

  • Publication number: 20200130175
    Abstract: An artificial muscle system includes a collapsible skeleton, a flexible skin, and a muscle actuation mechanism. The collapsible skeleton is contained inside a volume defined, at least in part, by the flexible skin. The flexible skin and the collapsible skeleton are configured for the flexible skin to provide a pulling force on the collapsible skeleton when a pressure difference exists between the inside of the sealed volume and a surrounding environment to change at least one of the dimensions and thus geometry of the collapsible skeleton. The muscle actuation mechanism includes at least one of the following to deploy or contract the collapsible skeleton: (a) a fluid displacing, releasing, or capturing mechanism configured to increase or decrease fluid pressure inside the sealed volume; and (b) a heating or cooling element configured to change the temperature of fluid in the sealed volume.

  • Patent number: 10562260
    Abstract: A pneumatic artificial muscle (PAM) actuator body can be formed from an elastic material that includes an inflatable chamber and a restraining component, such as flexible, but inextensible fibers, that causes the actuator to contract when the chamber is inflated with fluid (e.g., air or water). The actuator body can be cylindrical or flat. The actuator body can include a sensor layer formed of an elastic material including a microchannel filled with a conductive fluid to sense the expansion of the actuator body. The sensor layer can be configured to expand when the actuator body is inflated causing the electrical resistance of the conductive fluid to change. A sensor layer between the actuator body and restraining component can be used to measure changes in the contraction force of the actuator and a sensor layer outside of the restraining component can be used to measure changes in the length of the actuator.

  • Publication number: 20200015920
    Abstract: A multi-layer, super-planar laminate structure can be formed from distinctly patterned layers. The layers in the structure can include at least one rigid layer and at least one flexible layer; the rigid layer includes a plurality of rigid segments, and the flexible layer can extend between the rigid segments to serve as a joint. The layers are then stacked and bonded at selected locations to form a laminate structure with inter-layer bonds, and the laminate structure is flexed at the flexible layer between rigid segments to produce an expanded three-dimensional structure, wherein the layers are joined at the selected bonding locations and separated at other locations. A layer with electrical wiring can be included in the structure for delivering electric current to devices on or in the laminate structure.

  • Patent number: 10527507
    Abstract: An elastic strain sensor can be incorporated into an artificial skin that can sense flexing by the underlying support structure of the skin to detect and track motion of the support structure. The unidirectional elastic strain sensor can be formed by filling two or more channels in an elastic substrate material with a conductive liquid. At the ends of the channels, a loop port connects the channels to form a serpentine channel. The channels extend along the direction of strain and the loop portions have sufficiently large cross-sectional area in the direction transverse to the direction of strain that the sensor is unidirectional. The resistance is measured at the ends of the serpentine channel and can be used to determine the strain on the sensor. Additional channels can be added to increase the sensitivity of the sensor. The sensors can be stacked on top of each other to increase the sensitivity of the sensor.
