Building the Ultimate Racer - Part II

[by heitikender]Saturday, August 20th, 2005 at 2:45 am

How does our reality form? Modern day theories say that neurons are not the source of consciousness. Neurons are built from microtubules. Basically molecules, they harbor one particle in the center that is capable of a quantum state.

PART II

Visual system revisited (quantum consciousness)

When we are relaxed at our motorhome on Friday, these microtubules come to agreement about which state they in are approximately 40 times per second. When the mutually agreed upon result on state is 1, a neuron fires an impulse. And when the the result of those same states is 0, the neuron stays put. Either way, from all necessary neurons the reality we feel (see, taste, smell, hear, touch) comes to a standstill picture about 40 times per second. More than a film which is 25 (or 30) frames per second? Not to worry, our visual clock is slower still. And just before we race and during a race and on every practice we approach a fast turn, again those same microtubules’ quantum state collapses up to 80x per second. That’s an 80Hz asynchronous computer we’re talking about!

Now, nerve impulses vary from 0.3 m/s to 100m/s. For argument sake, let’s use the bigger number. When we touch something with our toe, and when we are 2 meters tall, we should feel it no faster than 0,02 second later. Can we SEE the differences between two events, separated by 0.01 sec? Yes. We can hear difference that is 0,004 sec apart. The problem is, when we touch something with our toe, we see and feel it simultaneously, at the same time. One explanation is that we have a slow vision system. The other is, brain can go backwards in time. No, not the brain the microtubule.

Tests have shown that the brain actuallyu fires up sometimes a couple of tenths before the actual nerve impulse. The solution is we anticipate the sensation and the brain feeds us first the anticipation and later, the real feeling. Now, lets use all that on our heads up display. Showing green glowing digital numbers representing current speed is so 80-s. Lets have several next generation x-boxes to render all visual field. Almost the same that a rider would see when looking just out of his/her (Katja Poensgen)? visor. But just “almost”. Lets make the road a little bit wider. Lets make the Corkscrew look almost flat and stretched out. That way the rider will think that he has more space and on the Corkscrew he has more acceleration.

If at the Brno race last year, Nicky would have been given such a helmet the computer would have erased a crashing Biaggi from his vision field and rendered him taking the corner successfully and later, on the straight Max retires with a mechanical problem, slowly stopping on the edge of the track. Even waving gallantly when Nicky passes. That way the computer keeps a riders attention on riding and not on crashes, which are more interesting to watch and easier to concentrate on. And that’s not all. Like on MotoGP4 on PS2, you can have your line from the previous lap painted on your virtual pavement with a big friendly blue color. And places where you braked, in red. Of course, you have your buttons under your left thumb to choose the braking point up to 10% later than usual and to avoid somebody doing the fast last lap trick the computer can guide your bike (and you) the same way you did on your previous lap. Every lap, right to the finish.


Optimal maneuvers (more mathematics than the doctor ordered)

For every corner-bike-tires-rider combination, there is the fastest way around that corner. Quite easily computable, too. That’s what the Ultimate racer is busy doing on first Friday practice. Of course, the computer has access to every corner on every track with every temperature and weather there has ever been a tire turned. With 3 teams, it’s six bikes. That’s some serious data to do safe generalization. And then, in the heat of the race, you’re approaching to corner waaay too hot.

The bike lets you reach those theoretical limits, then lowers the pressure on your tires, making a bigger contact patch with the pavement, brakes accordingly, notches down a gear, steers to the optimal point and sends a few impulses to the rider’s body to move where needed. Oh, and makes an evasive maneuver. At the same time, the other riders sees that he braked exactly on his brake marker, which is in the correct spot on the track to make a turn and that’s the way it goes. When later asked then he says he didn’t see the other rider who was about to overtake him.

“Race was good, a very harrrrd battle for sure.

Less orthodox ways around the track

Remember 1972? They started dragging the knee. 2000? King of Slide, McCoy showed how to take a corner with the rear tire spinning maniacally. Geometry changes, carbon disks, handlebars, swingarms… Everything has in racing has been transformed to something better, but there has been few quantum leaps. These are some of things I imagine when I can’t sleep and stare the ceiling:

Rolling knee sliders, legs as extra brakes by using the knee as a rolling point, just like tires; we have a totally stable and solid tripod. With the right size of rolling knee sliders, hell, mount extra tires to your knees! the corner speed will increase dramatically. For long corners, that may be even a second or more.

Missed your braking marker by about a mile? No problem. Slam the bike to its side, which is covered with a slimy, sticky, gecko-like substance. It won’t come off, it will not skid either. Just like that bubblegum on a hot day, it will stick, bend and stretch. Like a bad glue it will stick to the pavement. Up to 2G deceleration even. And no, you can’t use it on every corner. Just for those emergencies, like the last lap last corner when you’re in 4th position and you really want to finish on the podium. Or win.

Never liked those park and turn S-curves? Me neither. Enter the corner, spin the rear tire up, shut the throttle, grab the bike with your legs and hands like the devil wants to take your favorite bike away, and spend some quality airtime over the corner, landing exactly lined up. It takes practice, if not 9 lives, but it really works.

For the slow corners, endos are recommended. Brake it into corner and at the tightest part let your rear tire leave the ground and use the front tires gyroscopic force to turn your bike. Much tighter lines. You know you have the traction, you know you have reached to the limit of lean angle. Climb entirely to one side of the bike, making a true centre of the mass move even more inside the orner and letting the bike stand up a little bit. You can lean the bike even more then.

And these are not all the possibilities that theoretical models allow us to accomplish.

But for starters, these are a few nice tricks to start training on :)

    Heiti, for all our sakes, I sincerely hope you’re familiar with these rules.

    :D

    -jim

    p.s.. I *do* wonder, if racers used to watching NTSC video tend to be quicker than racers more familiar with PAL or the opposite. Seriously.

    Isaac Asimov is my favourite writer :) At the time of my university years (theoretical physics), I read and re-read most of his books. That’s the stuff that dreams are made of :)

    For PAL vs NTSC, I would rather be trained with NTSC. More frames and less info per each pic. Maybe brain doesn’t need all those frames anyway but there are not so much to look on track, 525 scan lines will do.

    Do you watch ‘Shakeys Tips’ on Bikes Aloud?

  4. heitikender Says:

    No I don’t. I’m from difference galaxy :) . Seriously - it’s not on Satellite TV it the area where I live.
    But you are more than welcome to share the info :)

  5. Michelle Dove Says:

    Heiti, sounds like a really interesting topic to explore, but I can’t help the reaction of ‘what the hell is he going on about?’in various parts of the article! not everybody has a degree in physics that will be reading this stuff you know! For us thickos out here, can you explain the points you are trying to make in more simple terms:)

  6. heitikender Says:

    Let me know where it goes out of focus and Im more than happy to explain :)

  7. Michelle Dove Says:

    all of it! haha I’m mainly interested in anticipation stuff..and what your point is leading to.

  8. heitikender Says:

    My point is, that we don’t really feel purely what nerves (optical and touch and balance, etc) tell to our brain, but it’s sort of mix on real and anticipated. It’s like lifting empty cardboard TV box - you think it’s heavy and you prepare yourself. And then, whatta suprise, it’s so light.
    Same thing is on the track. You brake and you have a general idea, where you end up. You steer and have a general idea, where the bike takes you. The problem is, when it doesn’t. And usually it doesn’t. And that leads you to correct the manuever. Over and over. Pro racer does about 1000 decisions per lap. Beginner - 3000. Do not anticipate. Plan ahead and execute. What they said in Matrix - “don’t think you are. Know you are.”

  9. Dr America Says:

    So, you are saying that to ride well, you need to be free of psychological hindrances. I mean hindrances like self protective processes, survival instincts, caveman stuff.

    And is anticipation a psychological hindrance to riding fast… we have an expectation of result before we take action- and that expectation clouds our perception. Like you say, a racer is often riding according to where he thinks he should be, rather than where he actually is…therefore he isnt as quick. A riders thinking seperates him from reality, and that seperation shows in the laptime.

    Is it possible for us human racers, to use anticipation when it is technically necessary, but be free of it also…so that we can perceive actual realtime facts of what the machine is doing? And can you be aware of the built in anticipation, and therefore disregard it?

  10. Angelus Says:

    God Damn!!! This s@*t be like the matrix!!!!!

  11. Jules Says:

    The concept seems so self evident, yet so utterly impossible to achieve ;-) Really enjoying reading this stuff, Heiti. Ya freak ;-P

  12. Michelle Dove Says:

    Dr America…I don’t think that you can be aware of the built in anticipation, and therefore disregard it, but it would certainly be an advantage to have an understanding of it. The right kind of understanding anyway.

  13. Dr America Says:

    Michelle said ‘I don’t think that you can be aware of the built in anticipation, and therefore disregard it, but it would certainly be an advantage to have an understanding of it’

    Well, if you have an understanding of it, not intellectual, but an actual real-time understanding…then surely you are aware of it. Aren’t they the same thing.

    Maybe you are confusing having knowledge of these built in anticipations, with understanding of them, knowledge and understanding arent the same thing my child

  14. Michelle Dove Says:

    Understanding comes from knowledge. Knowledge is an awareness gained by experience. To be aware is to be conscious of something. How much knowledge you have will affect your ability to perceive actual real time facts about what the machine is doing. Awareness and knowledge are the same. Impossible to disregard.

    Understanding separates theory from practice. To have a good understanding does not take much conscious thought. The effect is a reduction of psychological hindrances such as anticipation my Jedi

    what was the middle part again?

  16. Michelle Dove Says:

    the middle part?
