I was inspired by the motion platform construction of Billo's 6DOF and built a model of my planned motion platform. The platform will have a size of about 3,00x2,50 meters. Do you have experiences in relation to the rods end where the lever connect. Which are the best distance between the two rods of each site?
Surely the movements of the model platform aren't very exact, because I'ven't swivel heads, but metal eyelets with space. Insofar the movements are a little bit awkward by hand. Is it realy a smooth and exact movement with the real gearmotors in combination with lever and swivel heads controlled by software and Thanos boards? What's your experiences? My three-phase gearmotor (1,1KW/15U/min-456NM) in combination with Hitachi WJ200-015HF and Thanos board is working very well and synchronised by X-Plane too.
An additional question. Are there any difficulties in relation to to synchronization of the respective pairs of motors in connection with the platform and transmitting the force? Will it be all controlled by the software (in my case Ian's software), that there is no action of the motors against each other mecanical?
You can compare Fabi - Stevant - Billo's platforms to get an idea what is the effect of diffent distances between the rods. The software considers this as a single point so it makes sense to place them as close is possible (The inverse kinematics model is after a bottom triangle and top triangle).
After you are satisfied with the mockup model (enough travel or angles), you will see in the real life model that there is not going to be any conflict between the each motor mechanics. The software and electronics are cooperating to achieve safe positioning of the motors.
yes, I suspected it, that the movements of the six motors are depending on each other. I've found by my muckup also, that the junctions, especially the angel of the junctions are the limiting factors.
Below I've attached some photos of my mockup. First you can see the platform in low level horizontal. There are no problems with the junctions and lever. Next photo shows the platform tilted backwards (pitch like take off) and there are no problems with junctions, lever etc. Then third I tilted the platform to the left - oK- and moved the exzenter/lever only of the right gearmotor. in front up(the 5 other gearmotors not moving), then I get problems with junction angels und lever because it begins to jam. I'm not shure whether it's impossible movement of a single motor in real in combination with Ian's software, means it's closes off or would it be possible in real if the junctions would have a greater angel of movement?
the construction and development of my motion platform I didn't advanced tately, because I've to prepare the room for it. The room will get the size of about 16 m² and a hight of 4,50m. It's a lot of work, because I've to reduce my workshop and to set up news walls, a special floor with a load capacity of about 1,5 t and lay the electric system etc. I think it will take a lot of time. Maybe the real construction of my motion platform and the B737NG Cockpoit shell will start again next summer if everything goes well.
dureiken: Hi there, it's really quiet here someone could help me for my 6 dof project ? thanks a lot

tronicgr: dureiken Hi, Open a thread and I'll try my best to help. A little busy with Kickstarter details at the moment but I'll see what I can do.

fimmy: How's the firmware going?

tronicgr: @fimmy I had to put it on hold to finalize the manufacturing of the new kickstarter controllers. I tested parts of it to ensure compliance with the new features and looks good so far. I'll get back to it soon for integration.

Theuns: Very nice design.I'm also busy with mine and changing it also to Linear Actuators with 220v Servo motors.I'm waiting for my new controllers from Thanos. If I may ask Do you have any Sketchup files of your design and willing to share it I Thanks Theuns

atayeu: Hey everyone! I'm reading up and gathering all of the intel I can find for my first motion platform. this is by far best information for creating one.

tmcnam: I must be crazy but I still can't find the blueprints to the platform by GA-Dawg. Any help would be appreciated. Thanks guys.

Trip Rodriguez: Sorry tmcnam, the shoutbox doesn't get much attention. Did you find the blueprints? They are at the VERY bottom of the extremely long first post. It says "attachments: 6DOF.zip
