It really was

Hmmmmm, I've never seen this error before...as it has been many years since I compiled this .. and likely on an older ide version... It could likely have something to do with that ... I can try to compile it again sometime this week on the latest...and see if it is just you . But this is a first

i get it as well!!, ha.... i will spend a few min here and there tryna figure it out, prolly something duplicating a reference somewhere with the newer arduino ver... just gotta track it down...

@@Christopherknauf omg thanks! Thank you very much for taking the time to help me. I used the latest version of the ide and it gave me this error. How difficult is it to change the code to work on linear axes?

github.com/knaufinator/6DOF-Rotary-Stewart-Motion-Simulator/tree/Dev

added a dev branch, this one compiles now. I have not tested this on my rig,.. so i will keep this separate in a dev branch until i do.... I likely wont for awhile.

Bondo Glass, a high fill .. .filler, easy to gloop into place for shaping things,...

I am enjoying the build... But I keep running out of money!!,..

@@Christopherknauf I had that problem too.. mine started as a donor build.. but as I got deeper into it, it was more new parts vs donor parts..

@@Christopherknauf I actually live like 15 minutes from factory five. Both my shop and house.

Debating selling my sim rig to help pay, ... But I know that would be a tough choice even if it just sits in my basement unused,.... More of a trophy

@@Christopherknauf I know the sim stuff is such a winter hobby …

It keeps me off the streets

I keep saying that !!

Yeah,... I'm pretty stoked about it

i did, been wanting something financially irresponsible and dangerous in my garage for some time. fell in love with this idea, .. of a factory five cobra.... I am going to try to post updates as I dig into it,.. its going to take years and it would be a cool docuseries in the build process.

stay tuned my dude

@@Christopherknauf I sure will dude. Good job!

ive not touched my sim, it sits as a trophy to my life. life is good, never stopped building, and i try to respond to anyone who still contacts me about the project for interviews and advise on their own builds. Ive got big plans though, i just bought a racecar (factory five roadster), I will likely start some videos documenting the process... of... me ... making bad financial discissions......... i expect to get it in the next few weeks.. so stay tuned my dude!

@@Christopherknauf Looking forward to it!

Not without rewriting the algorithm for it to support the inverse kinematic for them, (ChatGPT could likely do it LOL).

@@Christopherknauf you can help me? iI have the same problem.. 6dof for linear

i would be concerned with safety first, there is a 4 point harness on this seat now, and it still can be scary fast, and it can buck you out,...if you are not strapped. may need to wear full leathers and helmet !!!

@Christopherknauf thanks for the reply! OK. If that's your main concern, I'll make it mine. I'll wear a dirt bike helmet and integrate the vr. I'll cover the gear and legs with something to protect if i landed on it. Ill pad the ground all around it and lots behind. One issue is there is no ground to slide your foot on, but I have some ideas, but that's for later. Just in your mind though, with it tuned to keep gravity into the seat and fake the lean, do you think the immersion would be like an 8 out of 10? This seems too good to be true but it should work amazing. I'm looking for reasons it won't.

i would really want to keep the lean in somehow, how dope would it be to lean all the way down during a high speed sweeping canyon curve!!,.. though from experiencing VR in my sim, i suspect it would be very difficult to achieve without being very motion sick. it would take some serious dedication and years of tinkering to perfect.

@Christopherknauf so I have put a lot of thought and chats with gpt4, the best way I can find is you don't lean the bike really you keep it in reference to the gravity and use the vr and force feedback in the bars to simulate the lean back to straight motion since it doesnt happen in real life. It will look 'wrong' if you aren't using it. But it should feel just fine. But yes, full lean is possible to simulate IMO. Plus loss of traction simulation the same as a car basically, then the tilt up for a wheelie, covers all your needs. A feed back vibration in the bike body for motor vibration and you're there... Thanks for the comments and inspiration.

i have heard of someone attempting it, i have certainly thought of it, but many challenges await, for instance,.. i dont want to put my feet/legs anywhere near the moving arms,!!!!

Yea, I am a machinist and I understand what you are talking about more than people should, lol. a flexible cover with a thick layer of foam on top i think at minimum. I did see a professional 6dof with a real bike on it, but the motion SUCKED. I want it to scare me, but safely. I will wear full gear if need be. Also was thinking about a wide hard cone that acts like a cat cone over their head after surgery and follows the bottom of the bike OVER the linkages. It's solvable I think. But is it WORTH it...I know that's personal but from what you're telling me it will be! @@Christopherknauf

I believe it

correct it was

kzbin.info/www/bejne/foSogYWpaNd6itk , Hit 21A @220v full tilt. 15 would certainly pop the breaker

It's likely to high of a frequency to get relayed into the motion platform at sane cueing settings...but if it was in the telemetry data.. it likely could be included.... Especially these days I filter quite a bit out in order to save my back

@@Christopherknauf Thank you for the reply. You can buy a 600W second-hand AC servo motor with drive in China for $80. How about the price in us? I'm a flight sim fan and often play War Thunder sim mode. I'm trying to DIY a 6dof seat that can yaw 360 degrees. I don't know if this will lead to a better flight simulation experience, so I would like to ask if you have tried it?

@@liutower316 about 200-250 after shipping per motor, these are 750w, could likely use 600 without issue as I have never hit limits. never used a 360 deg unit,.. from what i saw ,.. the common one out there only has yaw/roll/pitch,... just have to wonder if that is enough for you,.. would not be enough for me ...even though the yaw is 360,.. heave, sway and surge are nice to have as well. your results may vary.

Thanks!

github.com/knaufinator/6DOF-Rotary-Stewart-Motion-Simulator , in the readme, toward the bottom, I go over most of the must have parts, .. gears motors and such

@Christopher Knauf thank you for the reply. Me and my dad are planning on building a 6dof hopefully it goes well lol. 7k is a lot to buy one

The inverse kinematic algorithm is designed for this Rotary Stewart style, not the linear actuator you would have with a worm gear. Also the DC motor would likely require a different interface, as well pid controller to drive the motors to the right location accurately, something the ac servos do natively

its possible bubild this only with arduino or raspberry?

BTW you got SUBSCIBE ;) its amazing what you build.

I used the Arduino IDE, but with a esp32 instead of an actual Arduino board... The esp32 is significantly faster for when controlling all the arms and being able to calculate the inverse kinematic algorithm 1000 times a second. A raspberry pI may be able to do it...seeing that it does have a significant number of gpio.. The cost of an esp32 is significantly less than that of the raspi though...at 10$ ish. This project is all open source.. feel free to ask more questions
