Architected Elastomers as Load Bearing Actuators for Untethered Soft Robot Walking

open access: yesAdvanced Materials Technologies, EarlyView.
Electrically driven soft actuators that enable untethered soft robot walking are developed from 3D printed architected elastomers. The actuators have a handed shearing auxetic structure that enables fast, robust, and battery‐powered motions. The actuators are 3D printed from thermoplastic polyurethane on a desktop FDM printer.
