We had to do this on our arm for our robot in 2004. We had to use the big sprockets to make less torque on the chain meaning it would snap less. I'm not sure if that’s why this team has done it, that’s my guess.
As for 393's robot, where did you get those wheels and how much do they weigh? You have to be getting good traction with those. Deflate the tires a bit and you've got some serious traction.
