EPFL and NYU fish robot keeps its swimming performance from 0.6 m to 2.9 m

Researchers from EPFL and NYU built ScaFi, a tendon-driven robotic fish produced in three lengths from 0.6 m to 2.9 m that swims with the same motion at every size by changing only the tail rod diameter. Described in npj Robotics, the approach could simplify fielding quiet underwater robots that avoid disturbing sediment and wildlife, though energy efficiency across sizes remains an open problem.
