2DOF project

Hi started with the design
The roll motion will be a swaying motion ,Pitch will be tilting only the seat on top .
Wanted to check if this design will work

It will be used for both racing and flight
I thought that by changing the center of the roll angle the G forces will be more accurate

sorry for the bad drawing

No I will only use the sway/surge or pitch/roll motion .
What do you think ,will it work?
My intention is to feel the G forces
Any suggestions on the design will be appreciated (it's my 1st build still not familiar with the software capabilities)
Will be using arduino uno + 50A h bridge + wiper motor

Hmm, I only see 2 DOFs in the drawings:

• Motor 1 moves the seat on the reels, which are rolling on these curved rails.
• Motor 2 pitches the (rolling) seat.

So each motor alone seems to be responsible for 1 single DOF.

But what 3rd DOF do you see in the drawings, and what force/angle is it for?

(I just want to make sure that upcoming hints go in the right direction. )

Ok great so I'll have to provide more powerful motors
Regarding the design I think according to my researches it will provide the forces intended "definitely less than an actual race car" if not I'll add to it as I go .maybe change it to 3dof mounted on the rails as you said

Q: pitch/roll or surge/sway witch one will be better?

Hi
Started building the frame it's 84x44cm

Interesting. I never saw this approach before, and I am looking forward to see it in action one time.
Do you think of adding 4 additional reels below the curved steel tube, similar to a roller coaster (see image below)?

Otherwise the platform may flip to the front or back when it looses its balance, especially after you have mounted the seat with its pitch mechanics.

Interesting design. I will watch with interest and see how it all works out.

Hi Markus

Defenetly ,as you can see in my cad drawing that's why I kept enough space .
I only shortened it vertical instead of 40cm I made it 32cm because I want to add beneath the seat a third dof (heave) still under study

Thanks Fluke will try my best to make it work
Theoretically everything should work fine

Hi
Went to the scrap yard yesterday and found 3 Mercedes 450sel wiper motors and 4 huge power window motors FOR FREE .
Managed to have 2 wiper motors and 2 power window motors working
Wiper motor : 70 rpm
Power window : 80 rpm
Going to use 1 of each

Hi @RacingMat
downloaded your 2dof and 2pin direction Hbridge code ,please can you check if the hbridge I bought is compatible
if you can provide a wiring diagram I will be greatfull

this will be the pitch or surge

almost done with the mechanical part
