Embodiments in accordance with the present disclosure are directed to apparatuses used for reaction screening and optimization purposes. An example apparatus includes a plurality of reaction vessels, a dispensing subsystem, at least one reactor module, an analysis subsystem, an automation subsystem, and control circuitry. The dispensing subsystem delivers reagents to the plurality of reaction vessels for a plurality of reaction mixtures having varied reaction conditions. The at least one reactor module drives a plurality of reactions within the plurality of reaction vessels. The analysis subsystem analyzes compositions contained in the plurality of reaction vessels. The automation subsystem selectively moves the plurality of reaction vessels from a location proximal to the dispensing subsystem to the at least one reactor module based on experimental design parameters. And, the control circuitry identifies optimum reaction conditions for a target end product based on the analysis.

A flexible exosuit includes rigid and flexible elements configured to couple forces to a body of a wearer. Further, the flexible exosuit includes flexible linear actuators and clutched compliance elements to apply and/or modulate forces and/or compliances between segments of the body of the wearer. The flexible exosuit further includes electronic controllers, power sources and sensors. The flexible exosuit can be configured to apply forces to the body of the wearer to enable a variety of applications. In some examples, the flexible exosuit can be configured to augment the physical strength or endurance of the wearer. In some examples, the flexible exosuit can be configured to train the wearer to perform certain physical tasks. In some examples, the flexible exosuit can be configured to record physical activities of the wearer.

Electrolaminate clutches for an exosuit system

Systems and methods are shown for electrically controllably transmitting power from a motor involving electrically controllably coupling the first input hub to a shuttle so that power is transmitted from the first input hub to the shuttle, providing for one-way rotation between the shuttle and a stationary chassis, and coupling the shuttle to an output hub with a spring such that energy is stored and released from the spring as the output hub rotates. Examples are shown that include controlling engaged and disengaged time intervals of the first input hub and shuttle to maintain a torque level at the output hub, such as by utilizing pulse width modulation or pulse frequency modulation. Examples are also shown involving electroadhesively coupling the first input hub to the shuttle.

System and method for electrically controllable transmissions

Methods and apparatus related to electrolaminate clutches and transmissions are disclosed. A device can include: an input shaft that can be coupled to an electrolaminate sheet; an output shaft that can be coupled rigidly to a spring positioned over the input shaft, where the spring includes a tab that fits a groove of a spring capture ring that can be positioned over the input shaft; and a drum connected to an electrical ground between the electrolaminate sheet and the spring capture ring, where the drum can be coupled rigidly to the spring capture ring. Then, when a voltage is applied to the electrolaminate sheet, the electrolaminate sheet can clamp to the drum and impart rotation of the input shaft to the drum. The imparted rotation can cause the spring capture ring and the spring to rotate and clamp down on the input shaft, imparting rotation to the output shaft.

Twisted string actuators for an exosuit system

Exosuit system

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 10to 10ohms*m. The insulation material effectively operates to expand the conductive volume of the electrodes when they are actuated.

Materials for electroadhesion and electrolaminates

An active electroadhesive cleaning device or system includes electrode(s) that produce electroadhesive forces from an input voltage to adhere dust or other foreign objects against an interactive surface, from which the foreign objects are removed when the forces are controllably altered. User inputs control the input voltage and/or designate the size of foreign objects to be cleaned. An active power source provides the input voltage, and the interactive surface can be a continuous track across one or more rollers to move the device across a dirty foreign surface. Electrodes can be arranged in an interdigitated pattern having differing pitches that can be actuated selectively to clean foreign objects of different sizes. Sensors can detect the amount of foreign particles adhered to the interactive surface, and reversed polarity pulses can help repel items away from the interactive surface in a timely and controlled manner.

Active electroadhesive cleaning

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.
