Animals and robots employ central pattern generators, networks that invoke rhythmic patterns from constant inputs, to orchestrate limb movements during locomotion. Artificial generators (CPGs) can be either implemented in software or constructed a physical domain. The former lacks embodiment, inhibiting direct interactions with the world. latter is restricted by complex translation of abstract functions domain, e.g., negative feedback, if‐then behavior, etc. Here, self‐oscillators,...
Vat photopolymerization (VP) is a powerful additive manufacturing process to produce high-resolution 3D objects from liquid photocurable resins, but the mechanical performance of its standard materials restricts use in high-demanding applications.
