Tendon-driven, continuously bending manipulators whose changing shape and compliant contact complicate mechanical description and control.
Yale researchers built a microfluidic chip whose flexible fibers switch between two stable states, so each one can hold a bit of flow history. The Physical Review X study points to all-fluid controllers for soft robots, though the account of it describes only a chip.

University of Birmingham engineers and partners built a robotic time crystal that holds one rhythm through random disturbances. The authors see a route to robots with no central controller, but the tests described are two small structures.

NC State researchers built a soft feather-star robot that moves in three dimensions with two actuators, against the six usually required. The elastic wings and the timing of each actuator pulse handle control work that extra motors would otherwise do.
Reality
MIT engineers built a half-millimetre gel robot that swims up to four body lengths a minute on one layer of light-triggered muscle. The team expects the design to need less living tissue than bulkier robots, but it has not published a cell count, and a person still steers it with a hand-moved light.
Reality
The cross-embodiment model treats a robot's body as an input rather than a fixed assumption. For buyers, that turns hardware selection into a question about what transfers.
