[WIP] 6DOF on hoverboard motors and SFU gearboxes

https://www.youtube.com/shorts/TcfCrJLPs2M It's alive!!!

Oooh, nice!
I have a feeling this will be quite spectacular!

Hi,
Your project is very cool with an unusual kinematic for a 6 dof rig.
Great job !
How do you control the three odrive ?
And which software are you going to use to interface the game telemetry ?

Hi. I use FlyPT Mover. 3 ODrives are just connected with USB and visible as 3 independent serial devices in Mover.

Excellent work! This is very good. I'm interested in learning more about your project. I have some questions about the FlyptMove software and how it works.

How do you program the Makerbase ODrive3.6 56V controller board?

And how do you wire it to the motor? Could you share some information?

That's quite an impresive bit of engineering, look forward to seeing the rest.

Feel free to ask anything. ODrives are quite simple to connect, each board has 2 motor outputs and 2 encoder outputs. The only complicated thing is the software setup in console/odrivetool, but there's plenty of information on ODrive wiki.

And look this video if you want to connect a hoverboard motor specifically:


FlyPT mover looks a bit complicated. It works on 'nodes', you first make a source node, where you select game, then rig node where you input motion limits and rig dimensions, then pose node when you specify movement and which telemetry data moves which axis. Then output node where you connect your boards. You can even add more nodes of the same type and mix them to get desired result.

Now time for update:

Motion frame is ready. This is the first time I welded something like this complex 3D shape, with stainless steel tubes.
Some welds looks pretty, some ugly, but I don't care. They hold well. It was hard, but not that hard.






Whole steel frame weighs only 11,3kg, which is even lighter than my FFBeast joystick base (12,2kg)





FFB rudder pedals needed some modifications to fit in the frame. Wider base plate, and motor moved to the front and below the floor.



Lower seat part cut and 50W bass shakers installed.












To do:

-Wiring for stick,rudder, throttle, shakers, etc.
-movement calibration in Mover.

In the worst case when all of this will not work I have a nice tube frame for a gokart or something

Thats looking pretty cool, great effort on the frame.

You've already had the base working, so the rest should be plain sailing.
Look forward to future progress.

ElTakerPL@, thank you for the information. I'm starting to review it. I'm concerned about the configuration part you mentioned, as it's not my strong suit. If I have any further questions, I'll bother you with them. I hope I'm not being a bother.

Once again, congratulations on your work, and I'll be following your progress.

Really good outcome. I like the mechanical design, looks really well thought out.

really impressive rig , motion seems good too, what is the tilt noise wecan hear some times?

Barely noticable, only at full speed full range. Completely silent during play.

I have seen some rigs with that system that use a U joint between the motor shaft ans ballscrew instead of mounting the motor on a rotating shaft, what do you prefer as the best solution?

I don't trust u-joints. I think they will wear out quickly with constant vibrations, changing directions. Mounting whole assembly stiff with motor on a hinge seemed more robust for me.

When mine made that noise, I traced it to a loose bolt on the moving platform. I was only testing at the time, so will pay more attention when time for the final assembly arrives.

Just saying....

This setup is really impressive. I can definitely see a ton of work went into this project. Are you planning on release your CAD drawings and\or models? I'd love to build these type of setup. Thanks

I'll try to do it
