Engineers devise a modular system to produce efficient, scalable aquabots: The system’s simple repeating elements can assemble into swimming forms ranging from eel-like to wing-shaped.

Underwater structures that can change their shapes dynamically, the way fish do, push through water much more efficiently than conventional rigid hulls. But constructing deformable devices that can change the curve of their body shapes while maintaining a smooth profile is a long and difficult process. MIT’s RoboTuna, for example,…
