Abstract
Multistable metastructures can switch between multiple stable configurations without requiring locking forces. However, their potential for creating reconfigurable robots—metabots—capable of adapting to changing environments remains largely unexplored. Here, we report harnessing developable surface–based multistable thin-shell metastructures with high reconfigurability for adaptive manipulation and locomotion. These multistable metastructures are constructed by cutting and bonding thin polymer sheets with patterned cutouts, enabling programmable prestored elastic energy. A single unit achieves up to 20 stable configurations, while a four-unit assembly yields 256 reconfigured states, through simple folding of dynamic virtual creases. When integrated with thin sheet–based, multiresponsive soft actuators, these metastructures become highly adaptive metabots, including universal, noninvasive bistable soft grippers; magnetic multigait jumpers; and dual-responsive crawlers powered by magnetic and electroactive actuation. These systems exhibit high adaptability and maneuverability, capable of navigating complex terrains and confined environments via on-demand shape transformations, paving the way for energy-efficient, reconfigurable soft robotic platforms.
