Self leveling platform w/ a memsic 2125 and servos

Harry

I am new to the basic stamp but I am hoping for some guidance.

Has anybody tried making a small self leveling·platform using a tilt sensor (memsic 2125) and servos? Would I need to use stepper motors to get·a level value returned from the memsic 2125?

I'm thinking of using logic similar to the following:

If the value returned by the memsic 2125 on the x axis is greater than·800 then the servo will rotate the platform so many pulses in·a direction until the memsic returns a level value.

If the memsic 2125 was to return a value less than·800 then the servo would rotate the platform in the opposite direction.

The Y-axis would be handled in a·similar manner. Any help or direction to literature on the subject would be appreciated.

Thank you

Harry

The logic is sound ... time to start coding.· If you use servos to level the platform you should be able to make a near-direct move to level based on the axis values returned by the Memsic.

Mr. Williams,

So you're saying I should be able to extrapolate the values from the memsic in to pulse values for the servos to make a "near-direct" move to level?

Thank you

I would think so, yes. Of course, you have a closed loop system so you can always put it into a loop and move toward level.
