Making a object hover

So i’m trying to make a game where the player hovers around about 3/4m off the ground at anytime no matter the incline or surface, i tried using raycast and making it apply force when the object was at a certain height but that didn’t work, i was thinking that it would be good if i could use raycast to make sure that the height was always the same but to have it as a fast update so the player could go off a ramp at higher speeds instead of crashing into the ramp and causing problems. Any solutions or suggestions?

If you want to make it just as a visual effect, that is you dont need to react it from physics, you could fake the floating effect using single raycast and smooth up and down motion.
