In theory this drive system is identical to the behavior of a mechanum. I am not the expert on the math of the physics involved but yes it is a holonomic drive.

The DiscoBots also use corner omni killough drive.

Here is a 5th week video of the robot driving. http://www.youtube.com/watch?v=V0NorfAfvPs

We should have a final video out soon !

A comparison of omni vs mecanum (no h) forces can be found here. Scroll down and find the file "omni vs mecanum forces".

I like the drive system. The paint scheme makes the top look a bit like those 2-ton car jacks, you know, the ones with a red metal pyramid with a black post sticking out of it.
