At the Waterloo regional, I heard from Karthik that zero Canadian FRC teams bought Mecanum wheels this year. Maybe that has something to do with it?
Honestly, though, I think much of Canada's success comes from how much the teams work with each other. For example, 610 worked with teams such as 1241, 907, and 1310 throughout the season to practice and work on the robots. We also held a quick-build on kickoff day with several teams. I know that 1114 and 2056 also work with other teams in some way (or at least that's what I gathered from what Karthik said during the finals at GTR West in 2012). With some very good teams in Ontario and the high level of cooperation, this makes Ontario an example of successful CoopertitionŽ.
