BionicFinWave”s Undulating Fin Propulsion May Give Underwater Drones More Precise Control

Underwater robot with unique undulating fin drive. The marine planarian, cuttlefish and Nile perch have one thing in common: in order to propel themselves, they use their fins to generate a continuous wave, which advances along their entire length. With this so-called undulating fin movement, the BionicFinWave also maneuvers through a pipe system made of

No Motor, No Battery, No Problem

New robot concept uses responsive materials to swim through water. Engineers at Caltech and ETH Zurich have developed robots capable of self-propulsion without using any motors, servos, or power supply. Instead, these first-of-their-kind devices paddle through water as the material they are constructed from deforms with temperature changes. The work blurs the boundary between materials

Scientists Mimic Neural Tissue in Army-Funded Research

“Enabling a breakthrough in robotic augmentation of high-tempo military maneuver and operations requires disrupting the notion of an intelligent system as a rigid multi-body platform optimized for slow, carefully planned movement in uncluttered terrain,” Stanton said. “Fundamental research is needed to transpose smart materials from the current paradigm of fixed properties and mechanics with extrinsic
