One cylinder provides enough force at 60 psi to lift the entire robot, but we imagined that added complexity of the mechanical system needs to actuate all four wheels with a single piston offset any weight saved by eliminating the second piston. The second piston is only about 2 lbs. and it means that our actuation system can operate reliably with as little as 30 psi or so.
