3doF Motion Platform prototype

Low profile platform using triple Sarrus linkage in triangle position. 1:2 wooden scale model to test functionality.
Idea based on inmotionsimulation 3doF unit, but modified for cheaper drive and added weight-balance capability.
Video shows construction, motion tests and real-time interfaced to FS2004 and X-plane.

Fair enough. But great work i must say. I wonder how u thought of this; using sarrus linkage to achieve this. Have u patented ur product ? ? ?

[Rolandvanroy]

@aramidfiber The use of the triple sarrus linkage was based on a system from Inmotionsimulation. It is mentioned in the description of the video.

And your 3 DoF are 2 rotational and one translational as i see from the video. Can you make it purely 3 translational?

Also it is rotational only about 2 axis as of now, if you make it rotational about the third axis, may be you can simulation yaw motion.

@aramidfiber : Best would be 6DoF, with 3 translational and 3 rotational. But it's complicated. The yaw rotational can be implemented by placing everything on a rotating platform, like a giant lazy susan. But the whole thing needs more space, which I don't have at the moment.

Hey , looks too cool. Is it a ball and socket joint that you have used to connect the links to the top platform ?

[Rolandvanroy]

@aramidfiber : Yes, it's a rollerball bearing. The full scale platform uses rod-end bearings

@lennybogzy It is a special BFF driver software that is designed by Ian Hopper, seach for "buggies build for fun" website

[lennybogzy]

bravo!. How did you interface it to fs2004?

[Rolandvanroy]

This is a prototype with non optimal components. Therefore there is some stickyness in the movement. the actual model will use better motors.
