    "body_text": "Cable-driven modular soft robots can mimic animal curves, but mapping a target shape back to a buildable threading pattern normally requires expensive simulation and combinatorial search. This real-to-sim-to-real pipeline learns a forward surrogate and uses uncertainty-guided candidate refinement for inverse design. The reported surrogate cuts deformation-prediction time from 153,000 milliseconds to 0.0008 milliseconds, while inverse design falls from about 1.99 million milliseconds to 4.18 milliseconds. On 5,000 previously unseen threading patterns, 93 percent met the study's surrogate-based reconstruction criterion, and four physical robots demonstrated bioinspired shapes. The success rate is evaluated by the learned surrogate, so the physical examples are important but limited checks on transfer.",
