We love a bit of outside-the-box considering round right here, and anytime we see robots that don’t use wheels and motors to do the transferring, we take discover. So when a project touting robotic fish using soft-actuator fins crossed the tip line, we had to have a look.
It seems that this robofish comes from the fertile thoughts of [Carl Bugeja], whose PCB motors and flexible actuators have been lined right here earlier than. The fundamental idea of those fish fins is derived from the latter challenge, which makes use of coils printed onto each side of a versatile Kapton substrate. Positioned close to a magnet, the actuators bend when a present runs by way of them. The video beneath reveals two prototype robofish, every with 4 fins. The primary is a scrap of froth with a magnet embedded; the fins did flap however the entire thing simply weighed an excessive amount of. Model two was a lot lighter and virtually labored, however the tether to the driving force is simply too stiff to permit it to actually flex its fins.
It appears to be like prefer it has promise although, and we’re excited to see the place [Carl] take this. Maybe faculties of tiny robofish patrolling for pollution?
