content: I am not surprised that some grad student thought: "Let's play around with this."I am mildly concerned that their professor wanted to be associated with this "project".I am baffled that Rice University's public relations team considered this such a great showcase for Rice that they produced a video and published it on the University's official Youtube channel.

content: Quote from: Miyuki on July 27, 2022, 11:14:59 amWell, at least they are dead... Who cares about dead spiders?I am more interested in living Spiders rather than dead. I just hope that these people will not kill spiders just because they want to... Otherwise I will create a big mutant spider to avenge all other spiders!P.S. Joke. Or maybe no?

content: Quote from: Ed.Kloonk on July 28, 2022, 02:31:26 pmMuscles (at least in humans) aren't hydraulic, they're more like electrochemical amplifiers coupled to fibers that pull on each other when given an electrochemical potential change. The interesting part is that the fibers are either contracting or not and how many are contracting is how the force can be modulated, in other words in a way it's digital!

content: Quote from: Zoli on July 29, 2022, 05:09:58 amJust because you want it to be fake, doesn't mean it is. I see nothing wrong with the physics here, the air pressure is moving the spider legs just like the fluid pressure would when it was alive. Which is why a spider was chosen as other insects would have required a network of tiny wires.Plus that's not what deepfakes are, they're used to simulate people, not a dead spider on a stick.

content: Quote from: SiliconWizard on July 31, 2022, 11:29:12 pmMy problem is with the resistor extraction; I just don't see that kind of strength in spiders of that size. Unless it has some "extra skeleton" inside, you can easily broke apart the spider leg with the force less then necessary to pull out the resistor. Remember: the legs are NOT made of silk... And one more thing: spiders are fragile; a direct hit, which make a mosquito dizzy, it kills a similar sized spider(both fly away inertially, doesn't get flat).Now let's figure out, if some cheating happened on the breadboard:

content: That appears to be a jumper wire, not a resistor, but if you look carefully at the lengths of the leads before and after the spider picks it up, it's clear that it was nowhere near inserted; just sitting on the contacts in the breadboard. Yes, everything except superconductors can be a resistor. You know what I mean...
