why did you decide on three wheel holonomic instead of 4?
we did 4 this year for ease of construction/programming. it seems to be adding complexity and losing ease of construction to use 3, but you probably had a good reason...what?

In retrospect, it probably would have been easier and more effective to build a 4 wheel holomonic drive. The main reasons why we chose the 3 wheel design were: looks, weight and cost. The 3 wheeler also fits the triple play theme and our logo (the deltatech triangle) so it was fate. These may not be very "good" reasons, but like I said... it was fate.

Personally, I proposed the 3 wheel design because I was tired of building box shaped chassis's and I love to watch programmers go nuts.
