Do they manage the robot using a conSole?
Researchers at MIT have developed a robotic fish that should allow scientists to spy on intimate fishy moments normally unseen by human eyes. Fish, it has to be said, aren’t keen on humans and tend to hide when divers blunder too close with bulky underwater camera gear. To keep things discreet, scientists have developed a …
likely give target fish pause for thought, boffins used an acoustic modem,
Most fish hear far into the ultrasound and far into the infrasound. Natural adaptation to deal with clicky predators like dolphins as well as notice predators from afar.
The majority of fish are dumb as a brick. They could not care less about a cable dangling out of another fish. The only advantage this gives is improved mobility. It definitely has issues as far as "spooking" the fish is concerned though.
This weak little robot fish had better hope nothing large and hungry comes along. I really doubt it could outrun any marine predator in its size range. Perhaps there should be some form of defense for the poor thing?
Ink would be ideal; Cheap, not too bulky, easily deployed, looks way cool, and has served the Octopi well for ages.
The easy alternative is slap a camera on a wild fish
They do it a lot in wildlife filming, temporarily attached to e.g. a whale (yes I know its a mammal, but a sea one)
Not sure how "mini" the camera tech goes in terms of "minimum" size of fish that could be fitted with one (in terms of camera size & ability of fish to carry it)
