    Hi All,

    I just came out of a question, a lot of people love a frame mover and so as seat mover. For this topic, I always believe personal favor plays a lot in making a decision. However, will the limited experience in both system, I just thinking it is possible to combine both into one "complete" experience? Is it technically possible that current motion control software can handle the 2 kinds of system working together?

    Please correct me if I am wrong...

    My understanding or I should say my feeling is that, frame mover mainly simulating the sensation of the whole car, i.e. you feel the 4 suspensions moving during a turn / the car incline to one side, while seat mover, talking about making the same turn, your seat will incline to a specific angle simulating your seat is pushed by the g-force. These angles of inclination of the 2 systems supposed not the same.

    In real life, what we are doing is, we need to "feel under the seat" and also feel the movement of the car, i.e. the 4 suspensions, being a driver, we observe both kind of car motion at the same time, but come to motion simulation, they separate in 2 streams....IMO, it's not weird to have both in order to have a full picture of what your car is doing...

    Is it difficult / impossible to do this? Any issue similar to "motion cancellation in VR" would happen if 2 motion systems working together?

    as far as I know heave is limited to one axis only, that said it is limited by game and motion software.

    it can be done, but... you will need 4 motors, and all the electronics to move 4 motors... if you do so... why dont you jump straight to a 6dof, which as far as it has been said, it is the best experience posible...

    on the other hand, some time i rent for a couple of minutes a nice profesional comercial sim at a local pc store, it is expensive, and it uses 4 actuators each on every corner of the sim... it is expensive, kind of nice, but not that grate, still it is different to your idea.

    buy the way, simtools handle 6 dof, i guess your idea could fit into a 4 dof... so you could do it.

    i would explore first the idea of 3dof (traction loss) it should be really nice.

    Thanks all you guys comment, so far I haven't though about 6dof, too many limitations, size is one of the main issue...Actually I watched a few videos about 6dof platform, I don't know how to say it technically...Just think that a 6dof can provide all kinds of movement. But it just not exactly what I want....what in my head is a platform that can independently provide me feeling of the movement of a car and, feeling of seating on the seat....so that I can adjust my input with the 2 different sources....sorry for my lack of words.....just don't know how to make it clear....:rolleyes: wonder anyone has similar idea....:roll

    You want to use the frame to simulate the motion of the car and the seat to simulate G forces?
    It's the same thing just done differently, you can use roll pitch and yaw to simulate limited G's and you can also do the same with linear motion for short periods but the only benefit you will have is that you can potentially increase the total angular lean to 90 degrees if you have a 3+3 or 4+4 or 6+6 system. In terms of cost and complexity you're getting to the the point then where a 180/360 setup starts to make sense, other than the size problem, but keep in mind that you are trying to simulate a large world, so the smaller your motion simulator is the less likely you are to simulate the world accurately.

    I have seen a seat shaker mounted on top of a 2dof frame mover. looked neat

    I build a rig with such combination. Results are suprisely good, which gives far more realistic feel. Check my latest video on this. I can switch off one or other to compare...
    I can tell you that there is no way for me to go back either seat mover or frame mover alone. Both got to be ON.

    This is pretty awesome. Great job, @joe extraknow. Oh and this makes me wonder if I should strip my s2000 apart.

    Lol, I would keep the S2000. The deshborad and door panels are pretty cheap though. I got mine from local junk yard for $200. I got the side mirrors for under $100 from ebay.

    In progress making 225 degree curved sceen:

    wow joe xtraknow, thats brutal! Just one advice: get rid of the back rod that simxperience have for the seat actuators, Its just 3 scews I think and attach somehow the Scn5 directly to the back of the seat: less weight and no bouncing. But man what a rig!

    3 projectors?

    The frame looks like those trampoline frames, nice idea :thumbs

    I will try....I thought about before, but never try... thanks.

    @prodigy
    Yes, 3 projectors, bought two 10ft trampolines...for this screen frame.

    Joe Extraknow Well simxperience frames are really heavy and well built and even though I see your seat bounce very very litle it always does. All of them do and you want direct push from the Scn5 (does that expresion even exist?) Again, what a sim man!
