A Simple Free-Fold Test to Measure Bending Stiffness of Slender Soft Actuators

RA-L 2021

A reliable estimate for bending stiffness is critical to many soft robot models when predicting everything from robot-environment contact to buckling resistance. Current methods for predicting actuator bending stiffness rely on highly accurate knowledge of material characteristics, which are not tri

3D bioprinting directly onto moving human anatomy

IROS 2017poster

This paper establishes the feasibility of robotically 3D printing biomaterials such as alginate hydrogels onto moving human anatomy and a stationary plane. The alginate hydrogels used are in-vivo compatible and a proven biomaterial for tissue scaffolds. We developed a control scheme for precision ma…

Serially Actuated Locomotion for Soft Robots in Tube-Like Environments

RA-L 2017

Soft robots are able to complete tasks that traditional robots cannot, thus providing new opportunities for robots to navigate confined spaces. These tasks include pipe inspection and endoluminal surgical applications. The research objective of this letter is to present a design methodology for soft
