Motion platform
Gidday, Im about to embark on building a motion platform for a flight simulator.Does anyone have the soft ware to be able to run a two or three axis platform with 12v dc motors used as a type of stepper or can anyone design the programme for me.Im willing to pay for the right stuff. AS I am not into the electronic side of things.Give me a piece of metal and a welder and I can create.But this stuff is beyond me.Any help would be appreciated.

Re: Motion platform
Lool at Pololu, for eg http://www.pololu.com/catalog/product/712
however you may need to consider other options unless your flightsim is a 12" model... if you are accelerating hundreds of pounds, you will need linear (screw) actuators, big motors and likely big currents and higher voltages - ie 29-90 vdc.
you need to do some systems calculations on how much inertial load you have, house fast you want to accelerate it, an get a resulting required torque. then you need to chose an actuator type, (linear screw, rotary with gearbox etc), find a motor to match it, and a controller to match the motor. You'll likely need feedback to control this properly, eg encoders on the motors as well as a motion control system to handle 4 quadrant operation for coasting /braking. Now you've just gone into hundreds if not thousands of dollars (see BANNED for a good example.). This is not the kind of system you can just whip together using old 12v wiper motors! You also need to look into safety issues. If you just want a simple bang-bang control system, consider pneumatics for light loads or hydraulics for high ones. Solenoid valves are much easier to control than large ~horsepower dc brush motors. good luck!
