The Northwestern team used chemical synthesis to program the molecules within the hydrogel to respond to light. When exposed to light, the robot’s molecules become hydrophobic (repelling water), causing the water molecules to escape. This conversion causes the robot to “come alive” by bending from a flat position to “standing.” The researchers discovered that this bending enables the material to respond rapidly to rotating magnetic fields, activating its ability to walk fast.
