Fig. 6: Application of level-2 structures in self-deployable architectures.

Self-deployment into bridge and/or shelter-frame-like (a) and fully open 4-story building-like structures (b) with high loading capacity of over 10 kg (c). Scale bar: 3 cm. d Comparison among the total number of hinges, the total number of servomotors, the rotated hinges, and the actively actuated servomotors during the shape transformation shown in (b).
