A polymer-based device that can walk caterpillar-like across a surface has been developed by researchers in China. The marching machine, which steps out in response to swings in humidity, was made by Junqi Sun and colleagues at Jilin University in Chanchun. The device is based on a water-absorbing hydrogel polymer film, which is tightly bonded to a flexible humidity-inert polymer support.
In this video it is carrying more than 120 times the weight of the actuator.
