Snap‐through bistability is often observed in nature (eg, fast snapping to closure of Venus
flytrap) and the life (eg, bottle caps and hair clippers). Recently, harnessing bistability and …

Shape memory alloys (SMAs) are smart materials that are widely used to create intelligent
devices because of their high energy density, actuation strain, and biocompatibility …

Octopuses can whip their soft arms with a characteristic “bend propagation” motion to
capture prey with sensitive suckers. This relatively simple strategy provides models for …

Wireless soft-bodied robots at the millimeter scale allow traversing very confined
unstructured terrains with minimal invasion and safely interacting with the surrounding …

Biological organisms such as the octopus can reconfigure their shape and properties to
perform diverse tasks. However, soft machines struggle to achieve complex configurations …

Wireless millimeter-scale origami robots have recently been explored with great potential for
biomedical applications. Existing millimeter-scale origami devices usually require separate …

Robots with submillimeter dimensions are of interest for applications that range from tools for
minimally invasive surgical procedures in clinical medicine to vehicles for manipulating …

Hydrogels have diverse chemical properties and can exhibit reversibly large mechanical
deformations in response to external stimuli; these characteristics suggest that hydrogels are …

The limited force or torque outputs of miniature magnetic actuators constrain the locomotion
performances and functionalities of magnetic millimeter-scale robots. Here, we present a …

Millirobots that can adapt to unstructured environments, operate in confined spaces, and
interact with a diverse range of objects would be desirable for exploration and biomedical …
