Abstract: Material properties and composite structures play key roles in tailoring the performance of soft robots. Unfortunately, current design and fabrication approaches limit the achievable complexity and functionality in these two categories and as a result hinder soft robot performance. This talk will discuss approaches that allow the design and direct fabrication of novel soft robot composite structures. The processes combine computational topology optimization, to determine required three-dimensional multimaterial composite structures, and direct fabrication using an all-in-one fabrication workflow with resilient hybrid polymers, enabling precise tailoring of mechanical and functional properties. The library of polymer mixtures synthesized for compatibility with the processes spans five orders of magnitude in elastic modulus. Application examples in bio-inspired soft robots and sensors, as well as soft grippers will be described. The results demonstrate the potential of having an all-in-one fabrication workflow capable of producing tailored complex soft robot composite bodies.
