Fig. 2: Automatic design achieves efficient anti-parallel movement.

From: Automatic design of mechanical metamaterial actuators

Fig. 2

Comparison of (a) human-designed and (b) machine-designed structures for FEM simulated and (c, d) the corresponding 3D printed realizations. The color represents the Von Mises stress with the same colorbar as in Fig. 1c. Red (green) arrows indicate the direction of the desired input tinp (output tout). Resulting efficiencies are reported in each panel. For movement visualization see Supplementary Movie 2.
