Publication number: 20240068451Abstract: An actuator system includes an actuator with a deformable shell defining a pouch, a fluid dielectric contained within the pouch, and first and second electrodes disposed over opposing sides of the pouch, each electrode having two long edges and two short edges. The system also includes a power source for providing a voltage between the electrodes. The electrodes cover 50 to 90% of the first and second sides, respectively, of the pouch, and a gap is defined between long edges of the pouch and the electrodes such that, upon application of the voltage at one of the short edges of the electrodes, respectively, the electrodes selectively zip together from the one of the short edges toward an opposing one of the short edges. The system may also include a support structure for enabling the actuator to maintain its shape regardless of the voltage provided by the power source.Type: ApplicationFiled: August 23, 2023Publication date: February 29, 2024Applicant: Artimus Robotics Inc.Inventors: Eric Lucas Acome, Nicholas Alexander Kellaris, Shane Karl Mitchell, Jennifer Lyn Vigil

Publication number: 20240060519Abstract: A method for operating an actuator system includes providing an actuator with a deformable shell defining an enclosed internal cavity, a fluid dielectric, and first and second electrodes disposed over opposing sides of the enclosed internal cavity, and providing a power source such that the actuator system exhibits a first operational performance. Further, the method includes modifying at least one of length, width, diameter, and shape of the deformable shell and/or the first and second electrodes, a volume of the fluid dielectric, permittivity, thickness, and material of the deformable shell, and a partition within the deformable shell such that the actuator so modified exhibits a second operational performance. The operational performance includes force as a function of stroke, actuator breakdown strength, direction of actuation, uniformity of deformation of the deformable shell, actuator flexibility, and stroke as a function of actuator system volume.Type: ApplicationFiled: August 16, 2023Publication date: February 22, 2024Applicant: Artimus Robotics Inc.Inventors: Eric Lucas Acome, Nicholas Alexander Kellaris, Shane Karl Mitchell

Publication number: 20240052859Abstract: An electro-hydraulic actuator includes a deformable shell defining an enclosed internal cavity and containing a liquid dielectric, first and second electrodes on first and second sides, respectively, of the enclosed internal cavity. An electrostatic force between the first and second electrodes upon application of a voltage to one of the electrodes draws the electrodes towards each other to displace the liquid dielectric within the enclosed internal cavity. The shell includes active and inactive areas such that the electrostatic forces between the first and second electrodes displaces the liquid dielectric within the enclosed internal cavity from the active area of the shell to the inactive area of the shell. The first and second electrodes, the deformable shell, and the liquid dielectric cooperate to form a self-healing capacitor, and the liquid dielectric is configured for automatically filling breaches in the liquid dielectric resulting from dielectric breakdown.Type: ApplicationFiled: October 13, 2023Publication date: February 15, 2024Applicant: The Regents of the University of Colorado, a body corporateInventors: Christoph Matthias Keplinger, Eric Lucas Acome, Nicholas Alexander Kellaris, Shane Karl Mitchell

Patent number: 11827459Abstract: The present disclosure describes new systems and methods for influencing the rotational speed of a roller or other conveying systems and for controlling the speed, orientation or position of objects on a conveyor through the use of hydraulically amplified self-healing electrostatic (HASEL) actuators. HASEL actuators for such systems provide distinct benefits over traditional braking systems including: electrical control, eliminated need for an external source of pressurized air or fluid to allow use in certain environments, analog control of force or displacement in order to provide variable control of speed of objects on the conveyor system, and feedback to infer information about the state of the actuators as well as the state of objects being conveyed and/or state of the conveyor rollers.Type: GrantFiled: October 18, 2021Date of Patent: November 28, 2023Assignee: Artimus Robotics Inc.Inventors: Timothy G.

Publication number: 20230278477Abstract: A seating system includes a seat, with structures for supporting a user thereon, and actuators. Each actuator includes a deformable shell with an enclosed internal cavity containing a fluid dielectric contained, a pair of electrodes disposed on opposing sides of the deformable shell. The actuators are integrated into the structures and configured for providing at least one function, such as haptic feedback, seat adjustment, alert notification, vibratory signal, user input receiving, and massage function. A portion of the plurality of actuators may be enclosed within an encapsulating shell to form an encapsulated sheet of actuators. Each actuator may be a part of a button-on-demand system, wherein the actuator is normally in a collapsed position such that a user-facing surface of the encapsulating shell is substantially flat and, when activated by a user, the actuator is configured to expand such that the encapsulating shell is raised to form a button.Type: ApplicationFiled: February 6, 2023Publication date: September 7, 2023Applicant: Artimus Robotics Inc.Inventors: Eric Lucas Acome, Nicholas Alexander Kellaris, Shane Karl Mitchell, Timothy G.

Publication number: 20230091400Abstract: Systems and methods for grasping and manipulating objects are presented. The systems include a first actuator configured to either contract, expand, or rotate about a first axis. In some cases the actuator acts to deform a structure that is configured to grasp an object. In other cases the actuator directly interacts with an object to grasp the object or aid in the grasping of the object. The entire system may be connected to a robotic arm or other system to allow for picking and placing of objects. The first actuator includes a compliant shell defining an enclosed cavity, a dielectric fluid disposed within the enclosed cavity, a first electrode disposed on a first side of the compliant shell, and a second electrode disposed on a second side of the compliant shell opposite the first side.Type: ApplicationFiled: September 19, 2022Publication date: March 23, 2023Applicant: Artimus RoboticsInventors: Eric Lucas Acome, Nicholas Alexander Kellaris, Shane Karl Mitchell, Timothy G.

Patent number: 11486421Abstract: Hydraulically-amplified, self-healing, electrostatic transducers that harness electrostatic and hydraulic forces to achieve various actuation modes. Electrostatic forces between electrode pairs of the transducers generated upon application of a voltage to the electrode pairs draws the electrodes in each pair towards each other to displace a liquid dielectric contained within an enclosed internal cavity of the transducers to drive actuation in various manners. The electrodes and the liquid dielectric form a self-healing capacitor whereby the liquid dielectric automatically fills breaches in the liquid dielectric resulting from dielectric breakdown. Due to the resting shape of the cavity, a zipping-mechanism allows for selectively actuating the electrodes to a desired extent by controlling the voltage supplied.Type: GrantFiled: March 4, 2019Date of Patent: November 1, 2022Assignee: The Regents of the University of Colorado, a body corporateInventors: Christoph Matthias Keplinger, Eric Lucas Acome, Nicholas Alexander Kellaris, Shane Karl Mitchell, Timothy G.
