Hi Randy,
I have decided to get a Me Arm Kit with my own cash from the small allotment that I get from the business office here at the nursing home. It's only $40 and this way I can learn as well as create my own kinematics if I want to, or at least give it a try.
You'll recall that I was able to create a very simple trig expression for the robot that I designed to do the kinematics. I think it was just one of many possible outputs from forward kinematics that exist, but anyway it was fun to do.
With the Me Arm approach I can study the Me Arm and learn from it before revising the design that I created. You see, I came home and found that my NEMA 17 motors were either well hidden or stolen. I guess they LOOK expensive even though they are not. Nothing in this lab except the printer is expensive. And I can't run the printer because I'm on oxygen now.
