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. Read More >>

This Ingestible Nanobot is Powered by Stomach Acid 

There's tiny revolution happening in medicine, where micro- and nano-sized robots will someday cruise around inside our bodies, zeroing in on cancerous cells or repairing damaged but otherwise healthy ones. But before those ideas all become reality, those bots need a power source inside our bodies. That power source could be stomach acid. Read More >>
