Unsure 2DOF, 3DOF or 4DOF

Hi

im fairly new on, this forum ive been looking around and have been finding ideas, but unsure on 2DOF, 3DOF and 4DOF for a racing sim

I'd say im on a small budget but can expand on a later date, for now id like to know the differences in feel how do they compare

From what i can see i can either use motors or actuators? (if theres any big difference between the two)

Ive been looking at these so far

http://www.motiondynamics.com.au/worm-drive-motor-12v-24v-200w-180-rpm-20nm-torque.html

I know the first one comes with a gearbox but does the second one come one?


So far i know i need these for each motor

I need 1 u-joint

Not too sure what i need for feedback

Powersupplys are easy


And is it just one arduino uno

Would there be anything im missing?

Hi Simtoon welcome to our community. First advice from me would be to begin with a 2dof if you feel as a newbee. Later on the experience you can expand your rig by using the same components in a new rig. If you are a flight simmer a 2dof wouldn't give you a great immersion, imo in minimum a 3dof is suggested.

Hello @Simtoon , a seat mover 2DOF is the cheapest to start with and you can look at traction loss later if you like.
You have got all the needed parts it looks like. You will not need arduino with JRKS.
JRKS work on their own, and yes one per motor.
DC motors like what is listed will do the job.
The 25:1 gearbox motor will do fine for a shoulder mount seat mover like this

or a desk racer mount like this

Feedback is suggested a single turn 360 deg pot at 5k ohm and fitted to that back of the motor shaft http://au.rs-online.com/web/p/potentiometers/1642661/

drill a hole in the centre of the bolt to suit the pot shaft size, line it up on a bracket and drill and tap a 3mm bolt hole into the shaft and put a small bolt into that to hold the pot shaft still, I know I drilled right through it all in the photo.
Apart from rod ends for the motor connection to the frame and a seat, everything else is more or less set.
You just need to nut out a design.

@Simtoon , I suggest the motor http://www.motiondynamics.com.au/worm-drive-motor-12v-24v-200w-180-rpm-20nm-torque.html as it is a heck of a lot cheaper and will do the job fine.
Other link is a good motor, but a tad overkill.
Where are you based on this planet?

Thanks Dave, if your location isnt lying then your a backyard away

Do you need more powerful motors if your doing like 3 or 4DOF?

3DOF drift is a 2DOF balanced pivot riding on a big bearing and swinging from side to side, so those motors will do it.
If you want 3DOF lift, thats more technical, a bloke did it ages ago with 12v boat winch motors and a calculated spring under the centre to assist weight holding.
4DOF would be similar.
Costly
Although Blazinh uses 12v 800 watt motors with Arduino and h-bridges to have a 3 DOF lift frame, but thats an expensive build.

io ho un'idea penso innovativa..realizzare un simulatore con due motori che simula meglio le forze G..
