newby in the city 0dof -> 2dof -> 3dof

Hello everybody! As I promise in my introduction post I'll show you my advance in my hopefully future motion simulator in this thread. Also, ask for feedback & help . The idea is keep updating this post as soon as I advance, but I'll ask you patience, my budget right now is not enough to start buying and building... so I'll be doing step by step, and try to do stuff to can reuse it in the future.

My goal is have the most compact, portable and cheaper simulator as I can, so keep this in mind, almost all of the decisions will be taken thinking in the fact that I want to store the simulator...... wait for it ............ in the living room wall. I life in a very very small flat and I have no other place to put it jajaja.. so.. challenge accepted

STEP 1

I started getting the SketchUp and design something to plan my first purchase, the frame. Here what I have right now.


Note different things:
- I'm adding a pivot joint in order to make it flat when will be in the wall
- Definitely I will not going to use a rally seat (or at least a fixed one).. just adding it now because is still not clear for me what kind of seat I will adapt in order to unmount it fast and safe it all together.
- I will use an oculus quest 2, so I don't need screen, temporary I can use my living room screen too, is big enough to have it after the pedals (just guessing).

STEP 2 - 2DOF (2 actuators)



Just ignore the fact of the actuators are blocking the pivot join.. I know. I need to understand how actuators affects to the movement.. and motors, minimun size, etc first.

STEP 2 - 3DOF (4 actuators)



Would love to arrive at this point

And... now my first question.. I'm asking here for advice and help based on your experience, for the ones that already built stuff. My idea is ending up with a motion sim, so my first worry is .... the width of the frame (45cm) it's enough to have a good experience? I want to use, as showed before, linear actuators (homemade most probably).

My next step, the second, is going to be, search the cheaper possible place to buy the aluminium profiles, and start mounting the designed frame.. after that I'll update the thread with all the data, prices, and latest pictures


Thanks and hope you will enjoy seeing my progress of my project as I'll do!


PS. It's my first thread so... If I made some mistake sorry about that!

45cm width will be tight depending on what size aluminium you use and if you have or plan to use a 3 peddle set.

As for rotation, iv been repeatedly told less is more. I reckon you will be able to get the needed rotation with 45cm width as long as your actuators are strong enough.

Also if space is a premium like it is for me you could make the peddles attach to part of the rig that pulls out and locks in to place using t-slot rollers. Meaning that you can push them in to reduce its foot print when not in use

For the spacing is fine, my old structure (the one from my profile photo) was even smaller.

My worries was for the motion.. and I love to hear what you are saying.. seems like, with the correct actuators, will work perfectly!!

That's great, I will continue with this design then.

Thankss!

mmmm.. you think that it will be robust enough to support the actuators motion? just wondering that could have too much flexion.. And then I imagine that I should add another profile to have that stability compensation..

Right now the total length is 123cm, and will fit great where I want to store. But, I will take it in consideration.. I'm pretty sure it will not be the final design jajajajaja

Thanks again

FlyPt calculate the pivot point from each individual mounting position length and width of the actuator.

wooooooooooow, I guess you are referring to https://www.flyptmover.com, really really nice stuff! No more questions in here jajaja

I need to play with it and make sure I can adapt the design according in to it. I wanted to go deep on the actuators in more advance stage.. but in other hand I want to make sure to don't start building something that will be useless in the future.

Thanks a lot!!!
