Trajectory Generation for Underactuated Soft Robot Manipulators using Discrete Elastic Rod Dynamics
Beibei Liu, Akua K. Dickson, Ran Jing +1
Soft robots are well suited for contact-rich tasks due to their compliance, yet this property makes accurate and tractable modeling challenging. Planning motions with dynamically-f…
Force-Safe Environment Maps and Real-Time Detection for Soft Robot Manipulators
Akua K. Dickson, Juan C. Pacheco Garcia, Andrew P. Sabelhaus
Soft robot manipulators have the potential for deployment in delicate environments to perform complex manipulation tasks. However, existing obstacle detection and avoidance methods…
Safe Autonomous Environmental Contact for Soft Robots using Control Barrier Functions
Akua K. Dickson, Juan C. Pacheco Garcia, Meredith L. Anderson +6
Robots built from soft materials will inherently apply lower environmental forces than their rigid counterparts, and therefore may be more suitable in sensitive settings with unint…
Koopman Control Factorization: Data-Driven Convex Controller Design for a Class of Nonlinear Systems
Taha Ondogan, Ran Jing, Andrew P. Sabelhaus +1
Although Koopman operators provide a global linearization for autonomous dynamical systems, nonautonomous systems are not globally linear in the inputs. State (or output) feedback…
Soft Robotic Delivery of Coiled Anchors for Cardiac Interventions
Leonardo Zamora Yanez, Jacob Rogatinsky, Dominic Recco +4
Trans-catheter cardiac intervention has become an increasingly available option for high-risk patients without the complications of open heart surgery. However, current catheterbas…
Real-Time Trajectory Generation for Soft Robot Manipulators Using Differential Flatness
Akua Dickson, Juan C. Pacheco Garcia, Ran Jing +2
Soft robots have the potential to interact with sensitive environments and perform complex tasks effectively. However, motion plans and trajectories for soft manipulators are chall…
