Re: Robust way to rotate an 18 inch square plate 90 degrees.

Also, it seems strange to call something 1/6 as thick as it is in the horizontal direction a plate; is it really that thick?
Weight with its load ~ 3 lbs (I estimate the CG arc will be about 12 inches from center )
The measurements are the overall volume, the actual plate is more like an "L" shape probably made out of 1/8 to 1/4 inch thick material. (don't know yet, but I think the weight is correct either way).

Would like it to complete its 90 degree rotation in < 3 seconds (more like a slamming up action)

As an aside, who makes FRC compliant actuators, please? The one company I found last night https://www.servocity.com said his motor wasn't compliant.

Thank you.
