A Biological Curve Becomes a Soft Robot in Four Milliseconds
A surrogate-assisted inverse-design pipeline reports 93 percent shape reconstruction on 5,000 unseen threading patterns and physical demonstrations of four bioinspired forms.
Summary
A surrogate-assisted inverse-design pipeline reports 93 percent shape reconstruction on 5,000 unseen threading patterns and physical demonstrations of four bioinspired forms.
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.
