Publication number: 20230356862Abstract: A fabric-based, soft-bodied aerial robot includes contact-reactive perching and embodied impact protection structures while remaining lightweight and streamlined. The aerial robot is operable to 1) pneumatically vary its body stiffness for collision resilience and 2) utilize a hybrid fabric-based, bistable (HFB) grasper to perform passive grasping. When compared to conventional rigid drone frames the soft-bodied aerial robot successfully demonstrates its ability to dissipate impact from head-on collisions and maintain flight stability without any structural damage. Furthermore, in dynamic perching scenarios the HFB grasper is capable to convert impact energy upon contact into firm grasp through rapid body shape conforming in less than 4 ms.Type: ApplicationFiled: May 8, 2023Publication date: November 9, 2023Applicant: Arizona Board of Regents on Behalf of Arizona State UniversityInventors: Wenlong Zhang, Karishma Patnaik, Pham Nguyen, Shatadal Mishra, Panagiotis Polygerinos

Patent number: 11325163Abstract: Systems and methods for sorting utilizing an inflatable actuator are disclosed. A sorting system utilizing an inflatable actuator includes an inflatable actuator. The inflatable actuator is disposed in a cantilever beam orientation atop a support surface. The system includes an inflation component coupled to the inflatable actuator to provide an inflation force. Additionally, the system includes a control component configured to send an activation signal to the inflation component responsive to a detection of an object to be sorted. Responsive to the activation signal, the inflation component inflates the inflatable actuator to cause the inflatable actuator to make contact with the object to be sorted. The contact of the inflatable actuator with the object to be sorted causes the object to change from a first trajectory to a second trajectory.Type: GrantFiled: September 23, 2019Date of Patent: May 10, 2022Assignee: Arizona Board of Regents on behalf of Arizona State UniversityInventors: Panagiotis Polygerinos, Saivimal Sridar, Pham Huy Nguyen

Patent number: 11259980Abstract: A soft-inflatable exosuit for knee rehabilitation is fabricated in two different beam-like structures (I and O cross-section actuators) and mechanically characterized for their torque performance in knee-extension assistance. The fabrication procedure of both types of actuators is presented as well as their integration into a light-weight, low-cost and body-conforming interface. To detect the activation duration of the device during the gait cycle, a soft-silicone insole with embedded force-sensitive resistors (FSRs) is used. In evaluation studies, the soft inflatable exosuit device is tested for its ability to reduce muscle activity during the swing phase of the knee. Using sEMG (surface electromyography) sensors, the rectus femoris muscle group of a healthy individual is recorded while walking on a treadmill at a constant speed, with and without the soft device.Type: GrantFiled: July 31, 2018Date of Patent: March 1, 2022Assignees: ARIZONA BOARD OF REGENTS ON BEHALF OF ARIZONA STATE UNIVERSITY, DIGNITY HEALTHInventors: Panagiotis Polygerinos, Saivimal Sridar, Trent Maruyama, Christopher St. Clair, Christina Kwasnica
