It's hard to see how much mechanical advantage they have--looks like close to none--but 2 x pi x (1.5 in/2)^2 x 60 psi = 212 lbs; well more than enough.
The issue is that they are not using a 1.5 inch bore. Two 1.0625 inch bore will probably not be able to lift up the robot (and remember to take into account the added weight from battery and bumpers).
