Abstract Scope |
Developing untethered soft robots that utilize mechanically compliant bodies and soft actuators for bioinspired performance remains a grand challenge. State-of-the-art soft actuators are limited in their force output, power density, energy efficiency, and dependence on bulky, heavy power supplies. To address these challenges, we will present a collection of works that use architected elastomers 3D printed from thermoplastic polyurethane as motor-driven, bioinspired actuators for soft robot locomotion. We will present a load-bearing, multi-degree-of-freedom leg for untethered soft robots, a motorized artificial muscle for linear extension and contraction, and a demonstration of human-scale artificial musculoskeletal systems. We will conclude with an outlook on new directions in the optimized design and manufacturing of bioinspired elastomeric material systems for the creation of deployable soft robots that can practically operate in unstructured, real-world environments. |
