I saw the robot in competition, and it was great. I was really impressed with how you were able to speed accross the field at high speed, then push the mobile goal with little effort. I am guessing that this is a shift on-the-fly transmission. Could someone tell me how some teams have transmissions that cannot be shifted while driving, and others can? How are they diffrent? Sorry if these sound like stupid questions to you but, I do not know that much about drive systems.
