Atiny, jellyfish-like robot can swim like the real deal, carry beads, and burrow into a pile of beads. The robot has a soft body, is untethered, and measures 3 mm in width at its core. It has five swimming modes for which the time it takes for contraction and recovery movements of the appendages, called lappets, can be adjusted.
