Showroom 6DOF Build (Bodine Motors, Sabertooth, FlyPT Mover)

yes a gusset would help but i still dont think that will be enough. the motors are 13lbs by themselves. it will oscillate at the least.

Your the guy doin the welding....figure it out.....lol

@BlazinH

Possibly

Yes, I saw that too! But while it is friendly offer, who likes to take something to someone else to do it for them when they don't have too? Also, just because they both live in Michigan doesn't necessarily mean they live close to each other.

The facts are that although you wouldn't want to support motors by the motors only, he just needs to stabilize them a little bit. So 6 wood blocks and $12 worth of hose clamps will take care of the problem in short order without all the hassle.

Thanks @BlazinH. he does live very close. 10 minutes. We've talked on the phone also. So it's not impossible. But I also understand doing it yourself. Try the wood if that doesn't work gimme a shout.

maybe use a torque seal paint to see if they moved, like in aeronautics, and do a walk around before playing, like if it was a plane lol!! that is what i though of doing at first to see how it behaved.

Motor's would need to be "loaded" with a driver to see anything really.

Ok, so finally got all the electronics done and tested each MM & PS with SMC3. Mounting rods are done and feel very sturdy, just need to apply loctite on the nuts and ball joints. Platform is very sturdy and has no play whatsoever.

Need to solder 4 Hall sensors and I should be ready to test motion.

Another 6DOF is born. I hope testing goes well.

Thanks @SeatTime, i hope so too.

Need to read up on axis assignment and defining DOFs

We need videos !!!

@SilentChill, if it moves, there will be a video

Your control box looks amazing. I hope I can get mine that neat when the time comes. Can't wait to see the progress!

Thanks @GR88, Its nothing compared to what I have seen on this forum. I feel my setup is pretty basic.

I am trying to figure out how to assign AXIS. I am looking at @vulbas's assignment and I am wondering how did he come up with these values and why are some different for lets say Roll, for Axis 1 & 2. Is his assignment a good starting point? Axis 1 = Motor 1, Axis 2 = Motor 2......?

Good start point, but unfortunately it will be similar, but slightly different for every Stewart Platform sim. Can depend on how the axis's are numbered, direction of motion for each motor, which end you call the 'front' of the sim and also the geometry of the sim, as we are not using 6DOF maths - (which is why different % are also used to adjust for non linear movement) Note you will not get sway and surge perfect, but in reality it does not really matter. From looking at his setup Axis 1/2 are at the back and 3/4 and 5/6 are left/right.

Well since my sim is an hour away, I needed a way to understand how SimTools Axis assignment and Interface worked. I built a mini replica of my 6DOF and used two Arduinos/Interfaces.



On the actual sim do I need to have Startup Output and Shutdown Output populated?

just started playing around with simtools on my 6dof, my layout is the same as your replica. i used the above dof assignments from vulbas as a starting point and everything worked pretty much spot on straight away, which was a nice suprise!

as seattime said some of the movements are not completely flat ( we need to wait for simtools 2 and math plugin for this??) but its pretty much there.

Alright, so I finally tested motion and so far so good. Just debating whether I should mount my Obutto Ozone on top of the platform.
