Project Realistic Rig
« on: December 08, 2017, 02:10:31 PM »
Hello riders,

yes, i'm having the guts to call it "Realistic"... We'll see.
But i've been riding my bike and others this last week to check the mouvement. I'm driving bike for more than 30 years and i never really paid attention to the cinetic even after watching every week-end every possible bike race in the world...better later than ever...
And  then i tried to find a good way to reproduce what's happening on a bike AND that i could "ride" on my chair in front of my screen... --> GPB !!
Because i don't want do a real frame bike and having to use hydraulic or electric servo to shake, lean and move the frame. I don't have the room and more than that i don't have the money.

And so...
In red you have the handlebar that will be counter-steering to lean on the sides. This mouvement (vertical axe) will be short angle but hard to do (piece of metal into a big rubber that makes the mouvement harder - trying to reproduce what is real and what a steering absorber will do). The green piece will then turn left and right in a horizontal plan.
The blue part will be the driver leaning and can go on a horizontal axe from top to bottom, this will be a free mouvement, inside a "teflon" piece that will make the mouvement smooth (as in a bearing wheel).

Obviously, the feet parts are missing - brake and gear - and all the buttons on the handlebar but that easy stuff, what was annoying is to find a way to reproduce counter-sterring as it is in real life. I want a be able to ride in GPB without thinking of the device, just being absorbed by the screen. Like Assetto Corsa with a steering wheel, you forget about the device, you drive.

Now it's going to be time to make a prototype and then improve the stuff.

Thanks again to DD because he helped me a lot with the Leobodnar stuff and since HS1, HS2 and soon HS3, we have of excellence to follow, doing my best !!! (and if i could buy one and race instead of burning my brain into that rig, i'd prefer !!! )

good idea but i doubt it will be natural to move into 2 direction on the same mouvement, i think on axes for the steering and ed tracker for the lean will be more natural ! the other problem is that if you want to use counter steering, you must switch to DSA or DST hardcore mode, and thoses modes without ffb is very difficult to handle cause you don't have any feedback to know where is the bike lean limit ! anyways i wish you the best with your rig

Edit : Or may be it would be more natural if you move the steer in the mid of the lean axis, that way you controll the lean by pushig the handlebar instead of swinging it !

Hello Poumpouny,

and thank you for your feedback, i always consider than more brains are on a problem, better the solution will be at the end !!

And about what you says :
About natural mouvement, as i said i spent hours this last week analysing the mouvement, even put the GoPro of my son to film my hands and handlebar on my Pan European or on my other son ER-6 Kawa and i found on images what i was doing without really knowing.
And this mouvement, despite what you think, is or begging natural to me as every motorbike riders that ride for a while.

About the horizontal axe moved by the fact that i counter-steer on the vertical axe, this other idea (i post the "old" one - from 2 days) and this one is the news one from this morning at the breakfast time.
And i think that will absorb more the bike leaning mouvement to not trouble the rider leaning movement. Or, if it perturb anyway, i will have to make the rider leaning harder. I want to try anyway because that's how it feels to me.
About EdTracker Pro, that i use since it's out on the market, i will only put the Back and Front rider leaning.
I will be seating on my chair, not on the frame that's gonna move left and right.
So yes, want to ride a bike seating on a chair looks akward but that's the challenge.

About FFB, yes, i would love to FFB my vertical axe but i'm not sure (that was my question to DD) that the FFB is actually to copy the reality, meaning bloking me to turn if i brake hard, as in reality. And on a race, guys are allways braking to late and have to force down the bike on the side they want to go. Its natural centrifuge and centripete forces, plus the gravity and the wheels inertial mouvement. On the regular street bike, you brake, turn and the accelerate, on a race bike you gonna brake and turn but still brake on your turn (on the angle) so braking will have a tendancy to make the bike stand back up to the vertical and is going to refuse to steer and then you have to force it to put it into the curve, that's what i will love to find with FFB but i'm not sure it acts like that. (where to  catch the data for that ?, as i wrote somewhere else, as a Motec in racing cars).

And about DSA or DST i have no idea what is it, information in here and about the game is an archeology type of thing, so if you know what it is, i'll be more than happy to learn about it...

(what you say about vertical axe is interesting and i started to draw something like that but the draw isn't finished, i'll give it a try to the end of design and post it in here)




Edit : what you couldn't see in the other draws is that the horizontal axis on the handlebar is at the same axis as the riders leaning axis. So if i push my handlebar in a horizontal plan (to counter steer), it won't be pushing the rider leaning left and right.
And if DSA or DST doesn't give any feedback, i was thinking of using limiter after calibrating is done in order to give myself a max angle of 60 or something around that. (today, i'm using a joystick and a drum pedals with EdTracker on it for the rear brake, it's a catastrophy !! and i have no feedback anyway so...)
