And then you can get really crazy with the true longarm robotics such as Compuquilter, Intelliquilter, Statler Stitcher and lord knows what.
Please be aware that most if not all of these are not compatible with all frames and/or sewing machines. It is not the software so much as it is the hardware. I have a PC Quilter which is fine & dandy for the B-Line Studio Frame I started with but needs several modifications made to the ProFlex frame I now have. The Q-Bot hardware seems to be more easily adaptable but the software to design your own patterns is much more expensive and not included in the base price. It is really cool, though and I think I saw a "Grace" version of the Q-Bot and I don't know what the difference between the 2 is.
I haven't played with any of the others.
