Can a head mounted laser be far behind?
Researchers at the Massachusetts Institute of Technology have constructed a fish-like robot which they say will be more durable and safe for everyday use. Based on "soft" robotics technologies, the unit combines a computational system and power supply with a movement system based on a compressed gas pump and a series of tubes …
Definitely not far. It can now execute the "evasive action after successful attack" maneuvre.
Haven't a bit of trouble stabilizing the laser on target yet. The fishy motion is throwing the targeting scanners off a bit.
Wouldn't the other fish think it was a bit .... fishy?
What is it escaping from? A soft predator?
can't see it getting very far as they make no attempt to capture the "waste" stream from the "motor" and recompress it again. Should be a closed system pumping the gas from one side to the other.
Firefox (v27.0.1) - I get "Error #2035" instead of the video. I have Adobe flash player v188.8.131.52. This error seems to be "URL not found", though the video does play if I use MSIE.
Anyone else suffering this with Firefox?
Anyone know a solution (that doesn't involve using a different browser)?
Video works fine on Firefox 27.0.1 here. Check that you don't have multiple instances of flash installed (or that it's outdated and has been disabled by Firefox).
Disable https everywhere
I get this too
Disabling https everywhere sorts it
Running any script blocker add-ons? I get something similar (can not load plug in) with NoScript when playing some content, just allow temporary access and it works fine, does reload the page though.
As it stands, that robot is useless for watching other fish - it bubbles every time it moves.
Fish react very badly to air bubbles - dolphins use that reaction to shepherd prey into large balls where they can catch them more easily.
For this to be any use in ichthyology, the power source needs redeveloping. It remains to be seen whether or not similar performance can be created using something else.
Still - an interesting piece of work.
I was about to mention the same thing. I think that they should start experimenting with a pump, fluidics and a real fluid like water instead of air.
Both gas and liquids are fluids. Think you are referring to the use of hydraulics.
Obvious that the use of compressed gas is only suitable for the demonstration phase of this idea and it's to save on the complexity of having a pump/actuator and a larger energy source, valves don't use as much.
They're obviously also going to need to sort buoyancy and attitude control for any 'real use' situation.
Makes me wonder how is the thing moving vertically.
Look closely, it's hanging on a string.
So, how well does it do out of water?
"...they say will be more durable" than what?
The article on the MIT site does not mention durability!
"Designed to be more flexible and durable than traditional rigidly-built robot systems"
> the robots could be embedded with schools of fish to study marine biology and behaviors.
In this scenario, be interesting to see the actual fish trying to copulate with the machine.
Biology wasn't your strongest subject in school, was it?
Didn't you pay attention when you watched Futurama?
Just ask Fry about Lucy Liu ... ;-)
"I don't want to go out and earn money, I want to stay at home and make out with my fish-bot" doesn't quite have the same ring to it as the marylin monroe bot...
Fed up of the hard bodied fish robots getting away every time...try a c manoeuvre escape from that one, matey. But what wrong with an ordinary electrical actuator used in every other fish robot...sometimes engineers over think.
Throw it back.
Let the penguins have it.
You mean like Festo's 2009 robotic swimming and flying penguins?
"Unleash the robot turbot."
I for one welcome our pliant piscis overlords.
They could have made the gas vent backwards to give extra forward propulsion. Unless they were worried that if they did this it would look more rocket-propelled than fin-propelled.
