I am working on a machine design at work that will pick and place to stack a product. It has to be fast and have a large travel (8’ x 12’) with a 12 pound load. This seems to exclude the delta option I am planning on using a core XY design and servo motors to move a vacuum head around. I also need about 1inch of travel in the Z direction and a way to rotate ± 100 degrees. I’m trying to keep the head as light as possible so I have been thinking about ways to get the rotation and the Z up/down robust but light.
So far I am looking at using 4 Z motors to raise and lower the whole frame and possibly rotate the head using something like the core x/y so the rotation motors are in a fixed location.
There are a lot of smart people in this group so I thought I would see what you guys though of.
