  • Patent number: 11081975
    Abstract: The soft bodied structures and systems for controlling such devices are described herein. The soft bodied structures can, through a series of soft hydraulic actuators, move from a first position to a second position by a somersaulting motion. The system can include connecting to a first contact point of the surface using a surface attachment. The rigidity of the controllably resistive material can then be increased. The medial hydraulic actuators can be actuated to expand the exterior medial surface, creating a bend. The device can then attach to a second contact point using the surface attachment and the end portion actuator of the unattached end portion. Then, the surface attachment of the first attached end portion can detach. The medial hydraulic actuators and the controllably resistive material can then relax, followed by detaching the surface attachment of the second attached end portion.

  • Patent number: 11067200
    Abstract: Self-healing microvalves are described herein. The self-healing microvalve can move from a first position to a second position using an electrical input and use a soft hydraulic assembly to return from the second position to the first position. The electrical input can create an electrostatic attraction, causing the compression of the soft hydraulic assembly and movement of the valve gate to seal the microvalve. The elasticity of the soft hydraulic assembly can then return the self-healing microvalve to the original state, once the electrical input is removed.

  • Publication number: 20200407053
    Abstract: In one embodiment, a drone is provided with several inflatable tubes that each connect a propeller component to a body of the drone. In order to increase the handling of the drone, a patch is placed on the top surface of each inflatable tube that includes some number of shape memory alloy wires. The shape memory alloy wires shrink and become rigid when an electric current is applied to them. The optimal locations on each tube to place the patches, and the shape of the patches, is determined using a topology optimization. Later, the wires in the patches can be selectively activated or deactivated by an operating entity to provide an additional means to control the drone. Additionally, the drone is equipped with several landing arms which may include a shape memory alloy torsion coil spring to help the arm deployment during landing.

  • Publication number: 20200216121
    Abstract: A dynamic interface between a vehicle windshield and a structure (e.g., an A-pillar) is provided. The dynamic interface can be actively managed to allow its configuration to be selectively changed based on real-time driving environment conditions. The interface can include one or more actuators that can be selectively activated or deactivated to change the aerodynamic characteristics of the interface. When a crosswind activation condition is detected, the actuator(s) can be activated. The actuator(s) can be soft-bodied structures. The actuator(s) can include a bladder defining a fluid chamber filled with a dielectric fluid. A first conductor and a second conductor can be operatively positioned on opposite portions of the bladder. When electrical energy is supplied to the conductors, they can become oppositely charged. As a result, the conductors can be electrostatically attracted toward each other, displacing some of the dielectric fluid to an outer peripheral region of the fluid chamber.

  • Patent number: 10703361
    Abstract: A device and method for mitigating a vehicle collision are disclosed. The device and method include monitoring for an object within a vehicle travel path that includes a heightened travel hazard level. Upon detecting the object within the vehicle travel path, a closing distance rate, relative to the object, is compared with a closing threshold. When the closing distance rate compares unfavorably with the closing threshold, a secondary vehicle travel path based on the closing distance rate is determined, producing a determined secondary vehicle travel path. A command data output is generated for transmission to autonomously engage the determined secondary vehicle travel path.
