Insectoid Microbot Leverages Small-Scale Physics to Swim and Walk Underwater

Inspired by bugs, Harvard's Ambulatory Microrobot, or HAMR, can run, climb, make sharp turns, and carry small payloads. In the latest upgrade to the system, HAMR has been endowed with the ability to swim, dive down from the surface, and walk underwater--no small task for an object as light as a paperclip.
