HI, I have Qbot on my Viking 18x8 Inspira setup (made by Tin Lizzie) and I love it. The Qbot is a robot that is not brand specific and attaches to your stitch regulated machine and does your quilting automatically for you by selecting designs and you tell the robot where the top right is of your block or boder and where the bottom left is, etc. You can buy additional designs online from Golden Threads and others and it goes on an SD card that plugs into the robot. There is also a 4DQbot Designer program that you can put on your computer to make designs or change designs, now updated by Viking and called 4DQuilt Design Creator. This gives you unlimited possibilities of designs to put on the SD card. You can attach the robot to many different machines, see myqbot.com, and recently a salesperson said it will also work on the Innova. I have a friend who has a Qbot robot for sale for $2700 (no software) which is less than half price when there is no tax but although I don't personally think it's difficult as they have great instructions, you need to be technically able to attach this to your quilting machine.
