Constrained Goal-directed Planar Graph Generation with Grammar-based Reinforcement Learning
Nicolas Hochuli, Lorenzo Miele, Kristina Shea +1
Planar graphs are central to applications across science and engineering, yet existing generators provide limited support for goal-directed generation under hard structural and geo…
Computational Design of Active 3D-Printed Multi-State Structures for Shape Morphing
Thomas S. Lumpe, Michael Tao, Kristina Shea +1
Active structures have the ability to change their shape, properties, and functionality as a response to changing operational conditions, which makes them more versatile than their…
Volume Control of Low-Cost Ventilator with Automatic Set-Point Adaptation
Lukas Hewing, Marcel Menner, Nikolaos Tachatos +6
This paper considers the control design for a low-cost ventilator that is based on a manual resuscitator bag (also known as AmbuBag) to pump air into the lungs of a patient who is…
Autonomous Deployment of a Solar Panel Using an Elastic Origami and Distributed Shape Memory Polymer Actuators
Tian Chen, Osama R. Bilal, Robert Lang +2
Deployable mechanical systems such as space solar panels rely on the intricate stowage of passive modules, and sophisticated deployment using a network of motorized actuators. As a…
An Autonomous Programmable Actuator and Shape Reconfigurable Structures using Bistability and Shape Memory Polymers
Tian Chen, Kristina Shea
Autonomous deployment and shape reconfiguration of structures is a crucial field of research in space exploration with emerging applications in the automotive, building and biomedi…
Harnessing bistability for directional propulsion of untethered, soft robots
Tian Chen, Osama R. Bilal, Kristina Shea +1
In most macro-scale robotics systems , propulsion and controls are enabled through a physical tether or complex on-board electronics and batteries. A tether simplifies the design p…
