How much are hydraulics?

[Lilwolf]

And can I convert this into a sitdown cab?



I think it would be pretty !@# sweet playing starwars...

... and thanks for reminding me that I should have paid closer attention in sckool...

[ErikRuud]

Hydraulic actuators of that size would be very exspensive, not to mention the valves pumps and control circuirty needed.

Very cool though.

[Pieman2004]

Yeah I would think it would cost quite a bit. Of course then you have to synchronize their movements with the games, which would be too much for me. But you might could find some old hydraulic parts for cheap at a salvage yard.

[Lilwolf]

I was thinking that you could have it move based on your joystick movement...

And anytime that there is a lull in the action... it would slowly recenter.

Then add some extra motion for forced feedback and your set!

Of course... the chance of me NOT killing the cat when I turn left hard is...well... not so good...

toys like that are the reason that if i hit the lottery id be broke in 6 months..
thats sweet..load up burnout 3

Aint that the truth.

Awesome stuff right there, and one simply wouldn't be enough.

no kiddin!  i mean what good is a racing game without head on head action..
so thats 2 minumum..

 Games like Afterburner and Outrun used heavy duty motors instead of hydraulics.   Usually hydraulics  are a bit slow in reaction time... so drifty games are good with them.  But for fast jolts - motors or selenoids are the best.  A combination of all 3 would be great.

 I had been thinking of trying dual motors idea.   Wouldnt be too hard to wire it up.  However... I dont have the time,  space or $ for that right now.

How about the hydraulics used in lowriders?

Those can't be ALL that much...

[DYNAGOD]

theres an incredible amount of math involved in transalting and orchestrating 6 degrees of freedom into something cohesive. let alone translate into a set of feelings you can recognize (drift, accelerate decellerate,turn) and firthermore to apply movements to real time events in a video game.
Even if you built a custom hexapod, you would have to custom build software and drivers to run with it..

[DYNAGOD]

this guy built a hexapod for 2000.00$

i remember playing the jurassic park game at chuck e cheese and it had a force feedback seat that went along with the "tram" in the game..  those were good times..

While we are on the subject, how much would a 6 foot mechanical spider with death lasers cost?  

In all seriousness though, the hydraulic chair thingie would be cool.  It would probably be possible, but you would need to have a good handle on higher-math concepts to get it to feel right.  For driving games it might be possible to get a somewhat good feeling system by just reading controls, but then you have to consider bumps and such.  It would probably be pretty expensive whatever one could build.

[Xiaou2]

 Well, it looks like the guy who built the $2000  machine  hasnt really finished it... as there is no software to drive it.   Thats another technical hurdle.

 I do think using motors would be much cheaper, and easier.   My idea was just to make a limited gyro-chair like design.... that had 2 motors.  One for up/down tilting, and one banking left/right.   You could go all out and mount the entire thing on a motor driven spinning floor for an additional axis.

 The sitdown outrun cab was one of my fav's... really added a nice touch.   Later I ran into a Space Harrier SD that had a 25" or larger monitor on it!  I never cared too much for the game... but let me tell you,  with such a large monitor... and the fast gameplay + rocking machine... I litterally felt like I was strapped to a rocket!  ^_^   Giggling like a little schoolgirl all the way!  : )  lol

 If anyone has any scans of the sega sitdowns... Id love to see how they are set up internally.

they arent designed for quick reactions so they wouldnt be all that appropriate. i second xiaou2 s comment on using electric motors

[Shieldwolf]

While not entirely on the subject. I was actually looking into devloping  something like this for home theaters when I found someone had beat me to it. for about 5grand you can get your own

[Xiaou2]

 I didnt look at the site too closely.... however,  it looked like simple selenoidal movers.

  A simular effect can be done for much cheaper.   Aura created the "Bass Shakers".   Though they are no longer produced... there are many still floating arround.

  Basically, the shaker is like a speaker without the air moving cone part.  It uses the magnetic force to move a weighted unit so that it vibrates violently.  The low power bass shaker could make 30lbs force per foot!  
 
 I put 2 under my pc chair, and played a few mame games.  Freekin Incredible!   Its like a high power car subwoofer... but much more intense... without the need for super loud amplification and high pressure air movments.   I highly suggest them.

 Grab them and a low power sub-amp at  www.partsexpress.com

 or check ebay for people selling kits with them.

 There are other commercially produced 'transducers'.  One is called the "Buttkicker"  But cost about twice as much.  (but is like 5 times as powerfull)

I used to live across the street from a lowrider shop. The hydraulics in them use ALOT of juice. And much of the hopping action you see pictures of is more bouncing action as the machine is bouncing the tires off the ground (hard to explain, but the vehicle goes up higher and higher with each bounce, and they time the hydraulic thrust to help out with this effect. I used to have a truck with a worn out suspension that could get the front wheels off the ground using the same effect (working clutch, gas, and brake to make it bouce higher and higher until the tires left the ground).

Even the cars with the mild hydraulic setups needed two marine batteries in the trunk to run the stuff, and they drained quick. The competition hydraulic cars might have a dozen or more batteries.

Plus that stuff is not designed for constant use.

THIS is what you need...

me and the gf were down at Dave & Busters not that long ago, and they had a handful there... was pretty good.  of course this was the full 'deluxe' model...

it claims 6 degrees of motion, my not sound like much... but it does the job... besides, if you want/need more than that... you need R-360... which if you've got room for hydrolics, you've got room for this.

[Xiaou2]

btw - im pretty sure r360 is also drivin by motors.  Ive seen a video of it in action.  looks pretty cool.  

 heh...me needs a hydralic pipe bender... and space to put a human gyro!  : )

If you saw ABC Extreme Makeover:Home Edition last night, they put a teenagers bed on hydraulics, so it acted like a pimped out low rider with all the bouces and tilts.  Just use the same stuff (but they had to use steel to build it as they said wood wouldn't hold)
