A small library for the Arduino prototyping platform.
This library provides a way to evaluate, given some x, y, z coordinates, the needed motor positions of a Delta Robot.
For more information on the mathematics applied here, take a look at this excellent publication: R.L. Williams II, "The Delta Parallel Robot: Kinematics Solutions", Internet Publication, www.ohio.edu/people/williar4/html/pdf/DeltaKin.pdf, January 2016.
