Quasi-static modeling of everting vine robot bending and buckling during growth into obstacles, as well as retraction. (A) Modeling of bending and buckling based on environment interaction allows prediction of the pressure required to passively deform through an environment during growth. (B) Modeling of bending and buckling based on retraction forces allows prediction of when the robot will invert successfully. Modified from Haggerty et al. (2019) © IEEE 2019 and Coad et al.
