Fig. 4: Self-adaptation with varying environments.
From: Bio-inspired multimodal soft actuator with environmental self-adaptation

Motion switchability under fluid conditions with varying A light intensity, B viscosity, and C temperature. D Self-adaptation to the physical constraint. E Cart design for self-continuous locomotion with asymmetric trilayer, while the symmetric counterpart was blocked by the physical constraint. F Self-adaptation of the cart passing through the high-temperature zone (starting from i, passing through ii, and ending in iii). G Self-adaptation of the cart passing through the liquid-liquid interface with different viscosities.
