Question 6DOF with servomotors for flight sim in VR

the other problem of my rig is that I only have 200cm between ground and top in my room

I made a design like this but I really don't like :

Hi,

I am going back to wormdrive for now.

I would like 400mm heave, 120° of motor rotation, 6DOF, 35° pitch/roll



In term of angle :






What gives me 450 for platform radius :


Mobile :






Fix :






In a vertical plan (trying 2D before 3D), does the neutral position should be like this :




Or should I put the axis of fixation at the middle of lever, like this ?





I think I'm wrong because after having done all of this, I only have 15° of roll




Thanks for your help guys !

BTW I only have 15° lol

Hi

do this kind of actuator work ? or is there something wrong ? (except there is no screw ball and gear between motor and screw ball !








Thanks

Hi guys,

is that a problem if my seat is not at the center of rotation ?



because of problem of room size, I have to put the seat down of 350mm and back of 330mm.

Will it change the movment perception in bad terms ?

Or is that a problem for gravity center ?

Thanks a lot

Hi,

project keeps going !



30° pitch and roll, 70° yaw



400mm for/back and left/right and 500mm Heave



Do you know where I could find a seat where I can put my warthog joystick between my legs ?

And where to find gear wheel ? with chain ? would it be able to transmit 750w ?

thanks

Warthog extension... https://www.xsimulator.net/community/threads/warthog-hotas-extension.10345/

Thanks

is there a way to have one with an angle ?









et imprimer des parts :

at5 belts are more suitable, much less noisy and smooth!

I wil go with AT3 or AT5 thanks a lot

is 0.5m/s and 60°/sec good specs for VR ?

Thanks

500mm/sec it's a lot! (and difficult to achieve)
Nice actuator design, I have a similar but a little more radical design in mind if my more simplistic design fails this week.

thanks

where is your design ?

Dual ball bearing nut in the upper free floating part to keep it center...

What is your motor ? and linear spec ?

750watts, 12/24V 4300rpm 3NM (theoretically)

Hi guys,

still not dead, project keep goes up ! @wannabeaflyer reboosts me a lot !

Under fusion360 :




Screw lenght : 550mm, total travel : 480mm

And hardware in real :




I have a problem : the ball screw nut is in the wrong side compared to machined size, can I remove it and reverse it ?




What do you think of my design ? @SeatTime @wannabeaflyer @baykah @Hoddem @noorbeast

Thanks a lot

not a lot of help round there

You can unscrew it, but you need a piece of tube of the same size of the screw, or a printed screw.

Check @Hoddem 's thread.
