This 2DOF platform use Ian software too.

This one is really impressive man:

Where I can find Jan's software?
Thanks

If I can only hook up those servos to my pit I don't know if they would make them big enough.

Ian's motion software can be found here:

He's also working on a new design 3DoF that is more conventional. Check out the Platform 2 drawings and description on: http://buggies.builtforfun.co.uk/Sim/index.html

When building 3DoF motion platforms that require relatively low power drive, the key is weight balance. Both Ian's and my design make use of a bungee cord systems that counters the mass of the platform. Thus the servo's only need to accelerate the platform mass according F=m*a. I did some rough drive calculations with some interesting results. Details can be found on: http://simprojects.nl/platform_drive...ations_iii.htm

This is a very nice overview of the analytic process applied to motion systems. This sort of approach leads to better understanding and ultimately to better, safer projects. Roland's site is an outstanding resource and should be required reading for anyone thinking about a motion system.
