I remember seeing a demo of a delta robot a while ago and being very impressed. I have seen them used on assembly lines to quickly sort and organise objects but there are loads of other applications. I know of one company that uses a delta design for a tactile feedback capable interface device. I wonder if this sort of device would be good for routing/drilling/cnc type work? If you are interested in the maths behind this sort of design you can check out this pdf.
