I was remiss in not including the excellent machine from Lebanon in 1999. They had a very clever drive system.
My one issue with holonomic drive wheels (also known as omni-rollers or omnidirectional wheels) is that in the direction transverse to the 'major' direction of rolling, the effect wheel diameter gets pretty small.
I know that it can be made to work, but I still get a bit nerveous with wheels smaller than 3 inches or so. The holonomic wheels I have seen are much smaller than that when rolled against the grain.
Just my two cents worth.
Again, the idea is very clever and has some very cool advantages. I am only pointing out that there are some issues to be aware of when you are making your design decisions.
