Hello All,
I am involved in a project that is looking to build a 2-D gantry system.
We have at our disposal two simple stepper motor based laboratory motion
control stages. One is a linear stage and one is a rotory stage. To
get the idea of what these things look like, you can see similar
products at www.newport.com under their Motion Control line of products.
Our plan is to build a polar system, utilising the linear stage as the
radius and then mount the rotory stage on top of this to control the
angle. The goal is to position a platform under a stationary tool along
user defined Cartesian X-Y path.
We are aware that it would be just easier to use two linear stages
however we only have one linear stage and as many rotory stages we need.
Does this sound like a viable solution? Can anyone suggest an easier
solution?
And finally does anyone know of any sources (Books, articles, papers
etc.) that detail the control of such a system? Specifically we are
looking for information on how the stepper motors should be moved if we
want to move from point A to point B along a line? along a curve?
Sincerely,
James McMillan
