I'm now testing to see how this robot works
doing actual programmed movement.
Here I am makeing a 10 by 10 array of dots 10mm apart.

The hand making the dots.

A closeup of the dots. Not TOO bad.

The program that moves the arm in a 10 by 10 array.

The program that makes the hand move the pen and make a dot.
Pay no attention to lines 5 and 6!!!
