Does the Octopus Hold the Key To Robot Design? 347
balancedi writes "Simultaneously controling 8 jointless arms without getting them all tangled up is a neat trick that octopuses do with ease. According to a National Geographic article several researchers from around the world think understanding the octopus holds to key to the optimal robot design."
So, make slimy and slippery robots. Got it. (Score:5, Insightful)
What do you think hair conditioner does? It mostly lubricates the hair strands so it won't get traction and kink up onto other strands.
Are we going to build tentacle robots that are oozing oil along their smooth plasticene actuators? I think I've seen a few Japanese cartoons along this motif...

So basically the head says move and the legs figure out for themselves how to do it.

Interesting. This seems somewhat like the honda robot Asimo, in that Asimo also doesn't have just a single "brain" but rather a single primary processing unit and smaller controller units for each of his joints.
Sounds like good management or OO encapsulation (Score:4, Insightful)
Sounds like good management to me. Management (the octopus) assigns a task to one of their reports (arms). Tell them what to do, but don't micromanage the task.
Or, it sounds like encapsulation. Pass just enough information to the Arm object to communicate the task, and allow Arm's private methods handle the detals of how that task is accomplished.

Please leave the octopuses, lizards, snakes, iguanas, guacamayas, cacatuas, monkeys and others where they belong.

But, since octopus is actually an English word (regardless of where we got it from -- we borrow words, not grammar structures), it takes the regular plural of all English words that end in an -s, -es.
C'mon. Is the plural of sauna saunaa or saunat? A lot of our words come from other languages. If we have to adopt their pluarlization rules, that would be a nightmare laundry list of irregular plurals.

Sorry, but that doesn't make a damn bit of sense. It's either right or it's wrong to have an animal as a pet. You can't say "oh well our ancestors made these animals pets so they're okay."
If our ancestors had your attitude, we wouldn't have dogs, cats, cows, pigs, donkeys, horses, chickens, etc., as we know them.
So long as the animal is not threatened/endangered, it's captivity poses minimal risk to other living organisms (this includes humans, other animals and plants), and the habitat provided is proper, I don't see any reason to place arbitrary restrictions on what animals can be pets.

I don't think this carries over to farm animals simply because we kill and eat them! Maybe the animals on old-school family farms where the animals are treated humanely and then killed swiftly with respect live happy lives, but today's factory farms are sick and demented. The animals are tormented from birth to slaughter. If you haven't, check out The Meatrix. [themeatrix.com]
