Structural Design Principles

Precision-molded polystyrene joints carry every load path
Each connector rated for 200+ assembly cycles without stress whitening or material fatigue.
Frame-first engineering defines the skeleton before armor attaches
Internal subframe absorbs torsion and impact loads independent of exterior panel geometry.
Modular sub-assembly eliminates adhesive on standard builds
Snap-fit tolerances under 0.05mm enable full construction with flush cutters alone.
42 points of articulation without structural compromise
Double-jointed knees and ball-socket hips deliver full dynamic range under loaded armor weight.
