Incorporating force-distance information into MotorUI
Created by: samleachman
One thing that surprised me about this lab is that force-distance determinations are done outside LabVIEW, either using Richard's ForceInfo tool or a graph taped to the wall. The average force is a sum of two exponentials of the distance with empirically determined weights and decays. The distance can be calculated from the force in advance with a look-up table (with 0.01 mm precision or similar) or using LabVIEW's numeric solver. Incorporating this is crucial to implementing constant loading rate (pN/s) experiments, where you need to find the velocity to move the magnets. If you get around to this, I can share the code I used to implement this on my old setup in Berkeley.
