In addition to everything else that has been stated, remember the to pay attention to the height of the cart. Last year almost every robot had an arm of some type and as a result most robots were close to the max height of 5 feet. A few teams had carts that were 3 feet high to make the it easy to work on the robot. These teams had to take the robot off the cart and carry it through doors because the total was to tall. The pneumatic lift could be a good idea if it allows you to elevate the robot to work on it and lower it to fit through doors.
