Not sure how this thread got so derailed, but I love a good nerd out opportunity...

In a theoretical future, with infinite processing power and infinite speed, infinite software engineers, and perfect sensing technology AND perfect servo mechanism technology, all that weighs less than a human, an android could beat a human around a track.

Presently? Not a fucking chance, not with an infinite budget and the most advanced aerospace or military tech.

The human brain as we know it has the processing power of about 80,000 modern processors and processing speeds about 2500 times faster than that system. Additionally, there is evidence that we are underestimating the processing power of the human brain by orders of magnitude.

The human subconscious and reflex system, especially on the superhumans in motoGP, has a capacity to integrate a massive volume of incredibly subtle inputs and generate an equally complex collection of outputs that we are only beginning to understand. To imagine that an electromechanical system would be able to "feel" the clipons, tank, seat, and pegs with the same subtlety, process that information properly and at equal speed, and be able to respond properly with inputs to bar, tank, pegs and weight distribution is fantasy. A computer beating a human in Forza 4 is NOT the same as a computer beating a human in a real car on a real track (witness the Audi autonomous pikes peak car... pretty good, but not yet human), and DEFINITELY not the same as a motorcycle on which the rider is an integral part of the vehicle dynamics.

There are things that a computer can do better, right now, which is why the fastest way around the track is a human on a bike with pretty considerable rider aids, but those things are discrete and relatively simple and coarse, compared to what it takes to replicate the feel and response of a human fingertip.

and what part of that is actually simply used for navigating the vehicle? How much is simply idle, backup for future damage, memory storage, and overhead for the control of the body and doing nothing regards to the race? How much wasted on unnecessary access or loops and waiting for synapse response and feedback?

You can be typing here on BARF with a dual cpu quad core I7 with 8 gigs of RAM and 2TB storage with half that a swap file, so Windows 7 or 8 can keep its widgets running, and Firefox/Chrome/IE running while you type on the keyboard. Does this mean BARFing requires that level of gear? Not at all. Does having an OS that's good for using over a gig of RAM even at idle mean there is no way to argue in the Sink with less than a 2 gig system? Nope.

Birds and small animals can run, hunt, and evade better than humans with a much, much smaller synapse count-getting close to system complexity available commercially. How do they do it? Less BS overhead. And they're still the end products of a kludgy evolutionary process, as opposed to specifically designed and optimized hardware.

But everyone wants to think they're special, no way a machine can replace *their* unique talents, amirite? :afm199
 
ungh

I'm gonna go clean up

186mph in under 20 seconds from a stand still

"The 918 is so effortless to drive fast and forgiving at the limit that I'm quite sure it's is going to allow its owners to set multiple new records at their local tracks." You will never hear this said about the GT

And expect prices of the GT to continue to fall.

Actually no. I think you vastly underestimate the difficulty of riding a bike fast and how well the mind makes the thousand of tiny sub conscious decisions. I'm fast enough to know how very slow I am.

It's not a question of "replace". I am sure with enough money someone can build a riding machine. However the current tech is light years away. It's fucking complicated. Much more complicated than cars/catching baseballs/ making baskets. Like I said, give me the budget for a Manhattan project and it will be built. However, the correct machine will be an AI, and that's still decades away.

Again. You call the current systems designed and optimized :laughing The human/mammal nervous system has evolved millions of years to do many things well, including think, reason and process. You still have NO computers with the ability to process the evolution evolved thought processes/reactions at even a fraction of the speed the mind can. And you have to program them endlessly to do one task. Are computers amazing? Shit yes. Can they replace the human? Shit no. They can replace a human doing specific tasks that can be codified. Why? Because the nasty thing called "intelligence" is needed in complicated process like MotoGP racing, and you can't program intelligence, only duplicate or emulate it. In other words, copy the "kludgy" system. :laughing

at $400,000-$500,000 they are still out of my budget :laughing

there is an 05 in Fremont going for cheap - it's an automatic ($280,000) (needs new front bumper and passenger door and I would do a frame inspect - expect to spend $100k minimum getting it repaired / inspected) Looks like it's the Paul Walker special (too soon?) IGTH4T


The Spyder sits in at twice as much and technology wise is way more badass

And still really really far away from replicating the capability of a slow, dumb horse.
 
I'm not so sure why we're so bent on trying to emulate nature in the way something navigates terrain (like walking).

We didn't do that with flight, and we do flight much better than nature. DARPA needs to start thinking outside of the box and navigate terrain an entirely different way.

nature has evolve their designs over hundreds of thousands of years.

imitating existing, proven (natural) designs is a great starting place. this tends to get you farther, faster than redesigning something completely from scratch.

also, there are only so many basic modes of ground transport. wheels, treads, limbs/appendages, limbless. i wonder why nature didn't invent any animals that use wheels (although some roll) - maybe evolution decided it has too many disadvantages.

wheels/treads/limbless all have more restrictions on movement then using limbs. for maximum mobility on the largest number of terrains you're left with something that has legs (important for Boston Dynamic's BigDog robot which is a supposed to be a robotic pack mule).

do we? :dunno

based on what? The amount of energy we are required to expend to fly 1 human is quite high iirc

Birds don't have alcohol, bombs and DirectV on board…they also can't post to BARF while flying. Dumb animals.

I don't know. We see some pretty dumb shit posted on BARF, sometimes by people who are posting from an airplane after a few drinks. :laughing
 
One of my favorite vids of a falcon making it look easy
Skip to about 2:45 to watch it go from "Strolling in the park one day" to "Nuking it from orbit" in about zero-to-ohshit seconds.

The trajectory, descent, and last instant course change are really amazing.
