A helicopter gyro could sense the angle of the vehicle on any terrain and if hooked to an independent valving setup could compress or extend hydraulic cylinders to compensate; keeping things level. There are some fancy rock buggies that use air bags or hydraulics to more or less accomplish this idea. The ones I have seen are manually controlled though versus computer or gyro. It would be very expensive and involved to accomplish since you would be piecing everything together based on hunches. A forced articulation suspension designed to overcome antisquat, body roll, diving, and other negative things would be more practical.
