Traversing Field Obstacles

[Ginger Power]

I'm wondering if anybody has experience using pneumatic wheels on an FRC robot before. How do they work for traversing obstacles? How do they compare to more standard FRC wheels? I'm also wondering what other drivetrains/wheels teams have used to traverse field obstacles.

2013, 2014, and 2015 (not counting scoring platforms) were all devoid of serious obstacles in the field, and as a result there are many teams that have never had to deal with them. I'm particularly interested to hear how teams approached the 2010 and 2012 games.
